Nunki Micro Designer CH32V003

Description

NUNKI Micro Designer is a miniature development board for DIY projects
up to integration into more complex design.

It includes a CH32V003 microcontroller, input side protections, GPIO and
programmation ports for use with standard WCH-Link-E programmer using a
simple 6 pin IDC cable for Power, Programming and UART communication
with a computer.
