μHex - Low Power Controller [Discontinued]

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.

Features

* Hexagon design, compact size with 14 IO ports and 7 power ports

* 4 switchable power supply interfaces to reduce power consumption

* Two sleep-wake interfaces for convenient interactions with surrounding

* Designated Arduino development libraries

* Cross design in power and IO interfaces, directly supports 3 pin/4 pin sensor/actuator

* Large welding plate design

* 2.54 mm standard spacing plate
