CH32V003F4P6 Minimum System Board

This is an evaluation board for the low cost RISC-V core microcontroller by WCH. This MCU comes at very reasonable price with a rich set of features. 

It runs at 48Mhz and has 16KB Flash and 2KB RAM, and other general-purpose interfaces (GPIO, I2C, SPI, UART) available on most microcontrollers.

The MCU has immense potential in various cost-sensitive applications, especially those with high-volume demands. It can be an ideal solution for tasks requiring low computational power or IO expansion. With its versatility, the MCU opens up opportunities for efficient resource utilization and task isolation from the main MCU.
