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 [...]

The LANA-TNY is a compact development board created by Phyx and built around the CH32V203 RISC-V microcontroller. It offers a low-cost solution for embedded development and features a built-in USB bootloader, eliminating the need for an external programmer to flash the firmware. With a USB-C connector and a minimalist design, the board provides essential components to start development quickly. At its core, the Phyx LANA-TNY is powered by the CH32V203G6U6, a 32-bit RISC-V microcontroller from WCH Electronics, capable of running up to 144MHz with 1-cycle multiply/divide operations. It includes 10KB of SRAM, 32KB of single-cycle Flash, and 224KB of additional external flash for program or data storage, though the external memory operates at a slower speed. The CH32V203 microcontroller supports a range of peripherals, including ADC, timers, USB devices, UART, I2C, and SPI, making it suitable for a wide variety of embedded applications. Designed in the style of Adafruit’s QT [...]
