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 can support it standing by 60 days with using PIR sensor (SEN0171) as a trigger.
As it is using Atmega 328 Microcontroller, it has good general and powerful performance. It has 14 GPIO and 7 power ports (4 of them could be controlled) which could meet most of your project.
NOTE
- Please don’t update the bootloader since it is different from the Arduino Pro or Pro Mini one.
- Please connect an external power supply, if you want to make some large current application such as servo control.
