Description
1> M-mini module:
M-mini module is a WiFi module developed by AR9331 SOC chip. The scheme has the characteristics of low power consumption, low calorific value, stable function, perfect support of openwrt, etc. In addition, there are many players and a lot of information on the Internet, which makes the scheme popular with everyone.
M-mini module, leads to USB, TTL ports, I2S (three-wire system), 6 GPIO pins. Functionally, it is fully compatible with wr703n (uboot incompatible). There are open wrt software running on wr703n, 100% compatible running on M-mini. And M-mini has larger memory (64MByte) and flash (8MByte, 16MByte optional).
The M-mini module has been officially supported by opewnrt, openwrt.Barrier Breaker, trunk versionThere are corresponding models, buyers can download the source code of opewnrt directly to compile the corresponding firmware. Specific opewnrt compilation tutorials, Google and Baidu, there are many, please learn to refer to.

3> about M-mini Mach development board:
M-mini Mach development board is a minimal size development board for M-mini module. It is the same size as M-mini module (41.5*21.8mm).
Supports serial port, USB, and leads out three gpios (if not enough, they can also be welded to the foot of the socket on the floor, so that all the gpios of M-mini can be used).
Mainly for robots, WiFi cars, WiFi cameras and other applications of customers.
As shown below, the power supply of the development board can be operated by pin type, and the 5V power on the TTL line can be used.
4> about uboot:
This development board does not have a network port, so it can not use httpd to restore firmware, but our uboot supports USB brushing. The specific operation is as follows:
1. Change the name of firmware to flash on the computer to M-mini_firmware.bin and put it on the U disk (the format of the U disk needs to be FAT32).
2, insert the U disk into the USB port of the development board.
3, press the reset key on the development board to power the development board.
4. If the TTL line is connected, the status of the development board can be viewed through terminals such as putty. If there is no ttl, the reset button can be loosened after seeing the LED flash 3 times on the development board.
5, waiting for the development board to complete. The development board will automatically restart.
Attach the brush TTL chart:
Note: uboot does not provide source code.
5> about firmware.
In addition to integrating common functions (U disk mounting, samba), firmware adds mjpg-stream component and ser2net (this component has been integrated, to be tested). It is convenient for you to use as WiFi serial port and WiFi camera.
In addition, firmware adds WiFi relay enhancement components. Ordinary openwrt firmware is in the relay state, if the upper wireless can not connect (such as no signal, password asymmetry), the WiFi of the routing itself can not be launched.
After adding our components, even if the superior wireless can not be connected, the development board wireless is also launched, can be connected.
Buyers have good suggestions to discuss with sellers, and sellers add firmware functions as circumstances increase.
