The Internet of Things depicts a wonderful money to the manufacturer. It is predicted that by 2020, the global network market will increase from $ 655.8 billion in 2014 to $ 1.7 trillion, which is definitely the most developed industry in the future. one. In such a big context, whether it is a semiconductor business in the upstream, or the middle and lower reaches of the product plan designer, I have been in the top of the Internet. Taiwan's new Tang Electronics is one of them, launched a lot of development kits for the IoT field. Today, the panel is coming to talk, but the fifteentacious Numaker Uni Internet development kit.
Numaker Uni hardware
Numaker Uni is an Internet of Things developing board specially designed for Cavern, including a streamlined main control board Numaker Uni and ICE board Nu-link mini for download debugging.
The main control board Numaker Uni is only 3.5cm * 3.5cm, especially suitable for wearable product applications, onboard 802.11 b / g / n wifi module, Bluetooth dual mode module, and equipped with four functional modules, including gyroscope, temperature Humidity sensing components, IR transmission reception and RGB LED indicator, multi-function module allows engineers to use, with official routine guidance, no need to write module drivers yourself; another main control board also reserves 20Pin Multi-function pin, aspect engineers are autonomous.
Considering the design of the Internet of Things to low-power consumption, the main control board uses the new Tang low-power Cortex-M0 NANO100NE3Bn single chip as the core, the main frequency is 42 MHz, the characteristic support for wide voltage input voltage, support 3.7V lithium battery or 5V Power input, operating current in power saving mode is below 1 micrison, that is, if the 3.7V battery is powered, the standby time is 300,000 hours, whether it is a wearable device or a low power Internet of Things product It is extremely applicable. In addition, the NANO100NE3BN microcontroller also includes interfaces such as ADC, PWM, I2C, SPI, and UART, as a relatively universal low-power MCU product.
Some onboard resources of Numaker Uni are mainly shown below.
Numaker UNI Product Features:
32-bit Cortex®-M0 Nano100Ne3Bn MCU core, operating frequency up to 42 MHz
MCU built-in 128 KB flash memory and 16 kb static memory, working current in power saving mode is less than 1 micronia
Mounting sensors include: infrared transmitter, infrared receiver, three-axis accelerator and three-axis gyroscope (MPU6500), temperature and humidity sensor (HTU21D)
Rich peripherals, including: red / green / blue light-emitting diode, UART, SPI, I2C, PWM, ADC
Numaker also supports current popular wireless communications
[ESP8266] 802.11b / g / n Wi-Fi module (ESP-03)
- Support TCP, UDP Server & Client
- Support AP, STATION mode
- Support the AT command set
Bluetooth 3.0 dual mode module (BB2710-29)
- Support SPP and GATT PROFILE
- Support UART AT command set
In view, the new Tang Numaker Uni is a plate that is particularly suitable for the Internet of Things, wearable equipment. The board is equipped with low power MCU, not only the PCB area is only 3.5cm * 3.5cm, but also the panel popular WiFi / Bluetooth dual-mode Bluetooth communication module, a variety of sensor configurations, available for DIY peripheral expansion interfaces, also have a nice product industrial design, especially suitable for prototype development or secondary development.
In addition, the Numaker UNI development board is also equipped with a NU-Link ICE connector, with New Tang's own ICP tool support code download, and can be debugged by third-party IDE tools such as Keil Rvmdk, IAR EWARM.
Numaker Uni development
Learn about the basic hardware composition of Numaker Uni, then see some development materials for its development environment.
First, some hardware materials and software materials can be downloaded through the official download board.

Software Download address: http://www.nuvoton.com/opencms/resource-download.jsp? Tp_guid = SW0120160425215455
Hardware materials contain schematic, PCB, and BOM forms, this new Tang is still very high, completely open source. The software contains the library files, routines of the development board, and some documentation that are up to do, basically no problem, basically the basic board is definitely no problem. One thing is worth mentioning, because after all, the board is aimed at the Internet of Things, and the software data package also provides app applications and source code. For temperature and humidity on the board, but unfortunately only provides only the Andriod code.
When you discover a problem when you load the official code routine provided by the Keil IDE tool, some file paths are wrong.
Here are all modifications here.
Modifying can be compiled normally.
New Tang's matching board debugging tool usually built-in firmware is factory-in, waiting for you to update the latest firmware when you get the board.
Once upon finish, you can download it. The following figure is a simple RGB LED display.
debugging
In addition, the new Tang officially provides a rich routine with various functions such as WiFi / Ble, probably nearly 43, compared to a general MCU development board, which is much more truly.
If you are interested, you can buy it directly enough to buy, 199RMB, of course, if you want to try it first, you can access the DOP network's development board application.
More information about Numaker Uni Kits can access New Tang official website, have more detailed guidance, use of routines, chip specifications, etc., basic start development is not a big problem.
summary
New Tang launched Numaker Uni IoT development kit onboard popular EPS8266WIFI and Bluetooth dual mode module, equipped with multiple sensors and microcosmics of intelligent hardware products, such as RGB LED, motor, infrared, etc., allowing engineers to quickly Product prototyping. The new Tang's attitude towards the product through themselves, and continuously reducing the technical threshold while providing engineers, and saving a large number of R & D times for engineers, like this company's products are still worth paying attention.
