Note-1: CH32V002 can only be programmed by WCHLink-E through SDI interface (1-wire serial debug interface), so if it is the first time to buy the board, please buy it together with WCHLink-E.
Note-2: CH32V002F4U6 and CH32V003F4U6 have the same packaging and pin functions, so they can share the same PCB. The difference between CH32V002 and CH32V003 is that CH32V002 removes OPA, ADC changes from 10bit to 12bit, and SRAM increases from 2KB to 4KB.

Introduction

nanoCH32V002 is a development board made by MuseLab based on CH32V002F4U6 of QinHeng. It features 24MHz crystal oscillator，reset button and LED on board. It supports 1-wire serial debug interface (SDI) and all GPIOs are led out, which is convenient for developers to develop and prototype.

Features

● Onboard 24MHz crystal oscillator

● Onboard reset button

● LED indicator

● Powered by TYPE-C USB

● Lead out all GPIOs

● 1-wire serial debug interface (SDI)
