The ancients sometimes made a hero, and today, the Treatment of the Internet of Things has achieved today's wit.
Calculating the author is also the old user of the wit, the hardware development platform of Houbun has begun to contact, and then the 2nd generation of upgrades, now the latest Gokit3 generation It is not exaggerated that Gokit's changes have confirmed the wind direction of the market at the time, and the author is also fortunate to have a product from "also step" to gradually "mature".
GOKIT in the past
Before starting the Gokit3 generation evaluation test, you will briefly introduce the top two products of the handle cloud cloud and gokit2, and let you know the change of GOKIT.
GOKIT1 generation development board
Gokit is the first hardware development platform of Lishi Cloud. In the settlement set, the medium rules in the style. If you look back now, it is ugly, whether it is a card's process or hardware device, the layout of the interface is very cottage, but at the time Gokit is still very novel in the market, using the market very popular, very popular STM32 master, the WiFi module that is equipped with networked, plus a variety of interesting sensors, can be played and can play The sex is still very high, and it is just to meet the market trend of the high-speed development of the Internet of Things. It is important that engineers can apply for free, and Gokit is listed in the market, and it has also laid a foundation for the next market.
GOKIT2 generation development board
The Gokit2 generation can be said to be a leap of the wit, although the Gokit2 generation has no big changes, but the structural layout has made a lot of adjustments, and a piece of board design of the original gokit1 generation is divided into Gokit2 generation. This control board and the two plates of the function board are separated (and the main control board is selective and divided into standard plates and the Chuangke, the standard board is still using STM32 master, and the CMB has adopted the current market. The most simple Arduino development platform is connected, the control board and the function board are connected by the extended interface block of Arduino UNO, which can be used more flexible to developers, and you can use your familiar microcontroller control chip. The development cycle of accelerates products, the emergence of Gokit2 has also enabled markets that have a very similar surface card, such as Micokit, such as a small E development kit.

Gokit3
Nowadays, Gokit3, the initial impression, the change of the appearance and the gokit2 generation are not too big, the overall style has been formed in the 2nd generation, and it has been verified that it is more suitable for the current market trend, Gokit3 on the board The device layout, the interface has made a small adjustment. Of course, the most important is to support more WiFi modules. These content will be displayed in the following, now directly to see the gokit3 real thing.
Gokit3 development board
External decorations, like the first two generations, may be a bit rushing in Gokit3, even a different paper-on-hand guideline, but it is only temporarily posted a QR code of a Gokit3 electronic manual, and looks on the board. Many devices are obviously hand-welded, and the processing is relatively rough.
Gokit3 hardware
The Houbian main control platform that was taken this time is still a standard board main control platform of the STM32 series. It is a built-in WiFi module to give a lot of surprises. It is a very popular Yu Yin's lark7168, which is a Voice interactive WiFi module, for the current smart home series products have a very good effect (LARK7168 development board evaluation), in addition, Gokit3 also comes with the most widely used, most cost-effective WiFi SoC module - Le Xin ESP8266, these two WiFi modules make the author more satisfied.
Gokit3 development board, ESP8266 WIFI module
For the LARK7168 module of Yinye's world, since the module does not have a board antenna, it is necessary to access an additional WiFi antenna, which is not as convenient to the antenna of Lexin ESP8266. In addition, there are many small settings on the LARK7168 module. On the front, there is a MIC style collector. It seems that we can control some of the application functions on Gokit3 through voice. Is it a great?
LARK7618 WiFi module front
There is a MicroSD card with a microSD card, but it is rarely subject to the current information that is currently referred to, and the introduction of the relevant interface function on the LARK7618 module is not found.
Lark7618 WiFi module back
In general, the overall structure of Gokit3 has changed compared to 2 generations, but it looks not large, some of the functions taken in previous generations have retained, such as on the function board, motor, RGB LED, infrared photodetector, temperature and humidity sensor, etc. are all preserved, as shown below.
GOKIT3 function board front
Here is a little more attention to it. If you use it for the first time, don't go to the hardware, first follow the development process provided by the wit cloud, you are familiar with some of the functions and operations of the board, consider different transformations on the hardware. Or expand.
Like this Gokit3, a big change is on the extended interface of the WiFi module, distinguishes the MCU WiFi module extension and the SOC WiFi module extension, the default LARK7618 module on the board is the interface that lands the MCU extended interface. The WiFi module that came with the included ESP8266 needs to connect to the SOC-labeled extended interface, as shown in the following figure. In addition, when actually connected, the direction of the LARK7618 module is the side of the antenna near the motor, and the ESP8266 is just the opposite.
In addition to the Arduino expansion interface, the back of the function panel also reserved a LARK7618 extended interface, including I2C, MIC, USB and other signals, which is convenient for engineers to DIY, in addition, a USB turn serial port is added to the function panel, which is also passed and The same CP2012 turn serial chip is achieved on the main control board.
Gokit3 function board back
The basic and 2 generations of the main control board are not much different, but only a MicroSB interface, or it should be said to be moved to the functional board.

Overall, Gokit3's change is mainly in the optimization of functional interfaces and has increased many WiFi modules, and other changes are not too obvious than 2 generations. From the official website of Gokit3, the number of WiFi modules currently cooperated with Gokit3 has been very much. In addition to the above, various models of WiFi modules are also included, as shown below, as for specific support What extent, perhaps only the engineers who have used themselves have a say.
GOKIT3 is powered on
I have seen Gokit3 more than the first two generations of changes or more, let's take a look at the actual usage, and friends who have played the first two generations of Gokit should generally understand how to configure, how to power the operation board built-in The program, and for novices, the electronic manual on Gokit3 is equivalent to the rescue straw, and it is really no feeling of starting.
The gokit3 built-in program is an interesting application called smart pet egg, which can support WeChat, or APP control (Android and iOS systems). In the first two generations of Gokit, the author tried WeChat and Android App control, just trying to use the App usage under iOS on Gokit3.
First, download, install the general demonstration app Application app, which is installed, which can actually be a commissioning tool for wit.
After installing the APP of the IOS system, you need to set it to trust in the device management of the iPhone phone to open, landing in the mobile phone.
Step 2, configure the Gikit3 connection network, configure it through the AirLink configuration, add the device, WiFi module to select Yu Yin World. (Here you need to pay attention to: Gokit3 WiFi module does not support 5G)
Here you need your phone to access the WiFi network, and also configure the GOIT3 development board to enter the WiFi configuration mode (press the key2 button until the RGB LED shows green, as shown below)
The LARK7618 mounted on Gokit3, WIFI configuration is verified by sound wave mode, which is similar to the WiFi configuration in the evaluation article of the lark7618 development board.
However, it is not an intention to connect several times, it is a failure, prompts "There is poor network, switch to manual connection".
However, when checking the network connection, it is normal. When I don't know what to do, I'm exiting the app and then log in. It has been successful. It is a bit speechless. I don't know if it is a problem with the APP's interaction.
You can use the function on the app on the app to control the application function on Gokit3. Because it is a universal demo, there is no difference in GOKIT with the previous generation, and it is not a demonstration here.
In addition to configuring WiFi through airlink, we can also configure WiFi through Softap, and the different operations of the configured operation is just set up the development board. Just tap the KWY2 button, the RGB LED is red, and then via the mobile phone Connecting the gokit3's AP, then you can set up the app or web page, the specific operational process is no longer repeated, and there is a special document description in the developer community of the wit.
The overall experience of Gokit3 may bring us a richer interactive way - voice interaction, not only enhance the user's actual experience, but also let smart home and other scenes that need to be interacted directly with hardware. Diffrand is more natural. The research and development of an Internet of Things is inseparable from hardware. It is inseparable from software. It is not in the cloud service platform. Gokit3 brings us a rich combination of hardware, perfect software resources, and more complete wit clouds 3.0 , It has enhanced nine functions in the original Houyun 2.0, and fully enhances the service capabilities after the product access, further completing the transformation from the layout of the Internet of Things to the ecological construction, truly providing one-stop for users IoT full cycle development and operation and maintenance management service solutions.
At present, Gokit3 is in a strong free application in the panel forum, and the needs of the engineers are still hesitating, you can click to go to Gokit3.
