WeAct Studio CH32V203C8T6 RISC-V Low Power Core Demo Board

The WeAct Studio CH32V203C8T6 demo board is powered by the Qingke V4B processor, offering exceptional performance with a system clock frequency of up to 144MHz. It features 20KB of SRAM and 64KB of Flash memory, providing ample space for data storage and program execution. Operating at a supply voltage of 3.3V, the board’s GPIO unit is independently powered, offering enhanced flexibility for interfacing with external devices. The board supports various low-power modes, including sleep, stop, and standby, with ultra-low power consumption of 44.65uA/MHz in Run mode and 17.90uA/MHz in Sleep mode. It incorporates essential features such as power-on/power-down reset (POR/PDR), programmable voltage detector (PVD), 18-channel general DMA controllers, amplifiers, 12-bit ADC with TouchKey support, timers, USB2.0 host/device interfaces, UARTs, CAN interface, IIC/SPI interfaces, CRC calculation unit, 96-bit unique ID, and a serial 2-wire debug interface. This demo board is an ideal platform for developing low-power embedded applications requiring high performance and versatile connectivity.
