Note:

This version SMD is soldered, is much easier than 13804K version.
This is an unassembled kit, customers should have some basic electronic activity and ability, because of different levels of ability, we can not guarantee that everyone can DIY success, but we are committed to do our best of after-sales service.

Features:

Kits using ARM Cortex-M3 processor (STM32F103C8), and includes a 2.4-inch color TFT display can be used as ARM test development board.
Available source, Capable people can be secondary development on the basis of the suite, for example, it can be changed to Millivoltmeter, data loggers, and so on (we don't supply any technical support about that).
Circuit is simple and the kit is inexpensive
