General Application

Introduction
uHex 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 curre nt application such as servo control.
