CH32V003F4P6 RISCV Core Board with TYPEC Interface
UltraLowCost 32bit RISCV Development Board
This core board is built around the CH32V003F4P6 microcontroller, featuring a 32bit RISCV2A processor running at 48MHz [citation:2]. It offers an ultralowcost entry point into RISCV development with 16KB Flash and 2KB SRAM [citation:1]. The board provides convenient TYPEC connectivity for power and development.
RISCV2A 32bit Core - Open architecture with 48MHz performance [citation:2]
Wide Voltage Support - Operates from 3.3V or 5V with industrial temp range [citation:2]
Supply voltage is 3.3V or 5V with -40°C to +85°C industrial range [citation:2]
Use WCHLinkE programmer for 1wire SWD debugging [citation:2]
GPIO pins support 5V logic - check pinout for specific pin tolerance [citation:2]

Excellent Value Full RISCV development at minimal cost
Easy to Use TYPEC interface for simple power and connection
√ Supports MounRiver Studio IDE (MRS) [citation:2]
√ Compatible with Embeetle IDE for smooth development [citation:3]
√ 96-bit unique chip ID for device identification [citation:2]
Development Setup
The board supports MounRiver Studio (MRS) IDE or Embeetle IDE for development [citation:2][citation:3]. Programming uses a WCHLinkE programmer via the 1wire SWD interface [citation:2]. Some development boards integrate the flasher/debugger directly for plugandplay convenience [citation:3].
Install MounRiver Studio (MRS) for CH32V003 series support [citation:2]
Use USB TYPE-C for power connection (5V via standard cable)
CH32V003F4P6 requires WCHLinkE programmer (not WCHLink) [citation:9]
FLASH has 16KB capacity - plan firmware size accordingly [citation:1]
Troubleshooting
Core board not responding:
- Verify TYPEC cable supports power delivery (not chargeonly)
- Check WCH-LinkE programmer SWD connection
- Ensure 3.3V or 5V supply is stable
Programming fails:
- Confirm WCHLinkE support (not original WCHLink) [citation:9]
- Verify 1-wire SWD connections are correct
- Check target voltage matches programmer setting
