The 2020 new crown epidemic is a disaster, but it is also an opportunity to make people more clearly realize that many industries need to speed up transformation. The human interaction method of traditional industries is constantly challenging by human-computer interaction, which is one of the most important solutions that are currently accelerating and reduce costs. However, the challenges faced by human-machine interaction are also a variety of diversification: including from scratch, the system framework is not clear; hardware design does not know how to choose; software technology development is difficult, learning costs high, how to easily cross In the integration of these hardware and software resources, just focus on application development?
For market-oriented HMI products, reliable and guaranteed supply cycles are the primary reference factors for most manufacturers, therefore, use in environmentally harsh human machine interactive products, companies engaged in people's interaction program Generally there will be a unique solution, but if there is a more convenient HMI scheme for reference, it is a flexible recessive policy. The Maaxboard mini evaluated herein is a choice.
Maaxboard Mini is a British Based on the NXP IMX8M Mini series CPU development board, mainly for medical instruments, video surveillance, communication, IOT, and Chuangke, etc.
Hardware resources
The Maaxboard Mini uses a simple packaging, only one board body and one instruction manner.
The board is very small, only only the credit card size. However, although the sparrow is small, Maaxboard Mini offers a wealth of peripheral interface resources: including Gigabit Net, USB2.0 interface, MIPI-DSI interface, MIPI-CSI interface, Micro SD Card, UART, GPIO, WiFi / BT Wait, real shot is as follows.
Peripheral interface layout is shown below:
The specific peripheral interface resources are as follows:
1 40PIN IO port (extended 12C, SPL, UART, 12S)
1 MIPI-CSI camera interface
1 MIPI-DSI display interface
1 Gigabit Ethernet interface (RJ45 interface)
4 USB2.0 HOST high-speed transmission interface
1 TF card interface
1 8bit & 1 7bit GPIO port (scalable audio peripheral)
1 power interface (USB TYPE connector)
1 power button
2 user buttons
The main hardware constructs of Maaxboard Mini can refer to the following hardware system block diagrams.
Because the radiator and the NXP main chip "stick" is too strong, there is no dare to force, so it can only understand the I.MX 8M Mini series of NXPs by official information, the processor is the head of NXP Embedded multi-core application processors, using advanced 14LPC FinFET process technology, providing faster speed and higher power efficiency. With business and industrial grade certification and the support of the NXP products, Maaxboard Mini can be used for any universal industry and Internet of Things applications.
CPU characteristics:
Multi-core processing, 4 Cortex-A53 kernel platform, each nuclear running frequency up to 1.8GHz
32KB L1-I cache / 32 KB L1-D cache
512 KB L2 cache
1 Cortex-M4 kernel, running frequency up to 400MHz
16 KB L1-I cache / 16 KB L2-D cache
GPU characteristics:
3D GPU (1 shader, OpenGL® ES 2.0)
2D GPU
Out of the core processor, Maaxboard Mini does not work in other peripheral functions, and the function of differentiation with Maaxboard, for example, as shown below, changed the 2 USB3.0 interface of Maaxboard to The 4 USB 2.0 interface increases the number of USB peripheral connections, but the upper limit of the USB rate can be reached. Of course, this difference is not to talk about the bad part, only which kind of thing is suitable. In addition, I dropped the interface of the HDMI 2.0A of Maaxboard. This is more regrettable in my opinion.
Maaxboard Mini also uses a dual frequency WiFi & Bluetooth module AW-CM256SM, based on Cypus CYW43455 chip, size size is 12x12mm, support 802.11A / g / n / ac standard, 1T1R single channel, support BT4.2, WiFi Maximum communication rate 433Mbps.
In addition, MAaxboard mini is called MINI, but it is equally equipped with 2GB of memory.
Similarly, there is a 40pin extended interface for users DIY.
Used
According to the factory configuration, Maaxboard Mini only supports TF card launch or EMMC startup. I use the TF card to start this way, burning is the Debian system. It is worth mentioning that Maaxboard Mini supports multiple operating systems, and the two systems have been fixed for Maaxboard Mini, which can be bonded according to their own mirroring.
Use Win32 burning mirror to TF card.
Because there is no HDMI output, this is directly connected to the 7-inch multi-touch MIPI interface display, which is also the official product, the whole is supported, very good.
After the system is burn, the TF card is plugged into the Maaxboard mini.
You can see the boot system startup log directly from the screen.

The startup interface is shown below
Some basic applications are pre-installed in the system, such as terminals, file managers, browsers, video players, Camera photographs, and more, with each other's relationship.
Gigabit Ethernet Card
Search WiFi network
Connect WiFi for 5G band
WiFi Ping Circuit City website through 5G band
Use the officially provided touch screen directly to log in to the circuit city website.

summary
The board MAXBOARD Mini of this evaluation is another product in the Maaxboard series, which is slightly different in the same form factor, and the peripheral interface is slightly different (such as no HDMI interface, no USB3.0 interface, etc.), the function is slightly different. If there is no 4K HDR and video hardware encoding function, if you want to do a super HD audio and video entertainment product, we recommend Maaxboard. Throwing these factors, the experience of Maaxboard Mini is not much different from Maaxboard, but the frequency is higher, the power consumption is lower, the price is higher, and the user can choose Maaxboard according to their actual project needs, and Maaxboard mini, both Suitable for medical instruments, video surveillance, communication, IOT, applicable to fields such as consumer family audio to industrial building automation, mobile computers, and Outborn customers.
