μHex is the first low-power controller which is compatible with Arduino. It is very suitable for the battery power supply environment. A 210mAh CR2032 cell battery could make it work 60 days long.
As it is using Atmega 328 Microcontroller, it has good general and powerful performance. It packs 14 GPIO and 7 power ports (4 of them could be controlled) which could suit most of your project requirements.
Designed by maker Leo Yan.
Note:
Bootloader is write protected, please do not attempt to update Bootloader.
For large load applications (such as motor controlling), please connect VCC & GND directly or supply with independent power.
