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.
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.
