WCH’s CH32V003 has become one of the most talked-about microcontrollers in the embedded community, offering a complete RISC-V core for under $0.10 per unit.
Why CH32V003 Matters
At just 10 cents per chip in volume, the CH32V003 challenges the dominance of ARM Cortex-M0 parts in cost-sensitive applications. It features a 48MHz RISC-V core, 16KB Flash, 2KB SRAM, and a full set of peripherals including UART, I2C, SPI, and ADC.
