CAPUF Embedded has released the CH32V003 Dev Kit to simplify developers’ lives.
If an engineer or maker wants to evaluate or start learning about CH32V003, they have an MCU breakout board, which is not very useful. They need different breakout boards for different interfaces to explore the MCU fully. CAPUF Embedded identified this gap and came up with the idea of building a more useful development board. That’s how the CH32V003 Dev Kit was born.
The CH32V003 is an ultra-low-cost (10-cent) 32-bit microcontroller based on the RISC-V 2A core. It has a maximum system main frequency of 48MHz and features 2KB of SRAM and 16KB of Flash memory.
The CH32V003 also has a wide range of peripheral interfaces, including a DMA controller, a 10-bit ADC, an op-amp comparator, multiple timers, and standard communication interfaces such as USART, I2C, and SPI. The CH32V003 can be used in a wide range of applications.
CH32V003 Dev Kit Technical Features
