WeAct CH32V006F8U6 Mini Core is a compact, cost-effective development board featuring a 48 MHz CH32V006 RISC-V microcontroller, USB-C port, Reset button, and two 12-pin headers for I/Os with 3.3V or 5V voltage options.
Introduced in 2024 by WCH as an enhancement to the popular CH32V003, the CH32V006 offers more memory with 8KB SRAM, expanded storage of 62KB flash, additional GPIOs, and a 32-bit RISC-V2C core. WeAct Studio’s board is among the first third-party boards to utilize this microcontroller.
WeAct CH32V006F8U6 Mini Core board specifications:
SoC: WCH CH32V006F8U6
– CPU: 32-bit “RISC-V2C” core up to 48 MHz
– Memory: 8KB SRAM
– Storage: 62KB flash + 3KB “boot” flash
USB: 1x USB Type-C port for power and debugging
Expansion:
– 2x 12-pin headers with GPIO, ADC, USART, I2C, SPI
– I/O Voltage: 3.3V or 5V (model dependent, set by resistors)
Debugging: 4-pin debug header
Power Supply: 5V via USB-C port
Dimensions: 30.48 x 17.78 mm
WeAct Studio offers the CH32V006 datasheet, reference manual, PDF schematics, 3D STEP file, sample C code, SDK, and tools on GitHub. The board might be compatible with Linux using CNLohr’s CH32Fun project for a 32-bit RISC-V toolchain.
The MCU costs slightly over 10 cents, and the board itself is available for approximately $2.00 on AliExpress, with a 5-board bundle option. The package includes GPIO and debug headers; a WCH-LinkE USB debugger for flashing the board is also available for $2.99. If out of stock, the official CH32V006-EVT evaluation board is available for around $4.
