The CH32-Ant is a low-cost, breadboard-compatible development board powered by the WCH Electronics CH32V003-F4U6 RISC-V microcontroller, ideal for prototyping. It is pin-compatible with Prokyber’s ESP32-C6-Bug, offering an easy transition for users who don’t need wireless capabilities or the higher performance of the ESP32-C6FH4. The board features a Stemma QT connector for straightforward I2C sensor integration and a USB Type-C port that supports data transfer and power through software-based USB on the CH32V003.
The CH32-Ant offers configurable logic voltage at 3.3V or 5V, adjusted via an onboard 0-ohm resistor, providing flexibility for sensor projects. Powered by the CH32V003F4U6 microcontroller, it operates up to 48MHz with 2kB of RAM and 16kB of flash, making it cost-effective for applications requiring basic processing without wireless. The CH32-Ant features a compact layout designed for breadboard compatibility, a Stemma QT connector for an I2C module on one end of the board, and a USB Type-C connector on the other.
It’s far from the first CH32V003-based RISC-V development board we’ve covered and other such boards include the MuseLab nanoCH32V003, CAPUF Embedded CH32V003 Dev Kit, Phnx LANA-TNY, and Olimex RVPC.
The CH32-Ant development board specification:
- MCU – WCH CH32V003F4U6 32-bit RISC-V2A microcontroller up to 48 MHz with 2KB SRAM, 16KB flash (QFN20 package)
- USB – 1x USB Type-C port for power and programming
- Expansion
- 2x 12-pin headers with up to 16x GPIO, 1x SPI, 1x I2C, 1x UART, 6x ADC, +5V, +3.3V and GND
- Stemma QT connector for solderless I2C expansion
- Debugging – 3-pin 1-wire serial debug interface
- Misc – 1x Reset button and 2x LED
- Power supply – 5V via USB-C port
- Dimensions – TBD
The CH32-Ant features a 3-pin 1-wire serial debug interface for connecting to the WCHLink-E debugger. It is compatible with the Arduino IDE like other WCH boards. WCH Electronics also provides libraries for USB and debugging, while the board’s configurable 3.3V and 5V logic options improve compatibility with various sensors.
The CH32-Ant CH32V003 RISC-V development board is now available on Prokyber’s Tindie store for $4.99. A schematic is linked on the product page for reference.
