About this item

The WeAct Studio CH32X035F8U6 Core Demo Board is a compact, cost-effective development platform based on the CH32X035 microcontroller by WCH, featuring the company’s proprietary QingKe RISC-V core. Designed for USB Power Delivery (USB PD) applications, this board supports a variety of power management and control functions in devices like chargers, adapters, and PD-triggered peripherals. Running at 48 MHz, the CH32X035 MCU includes 64KB Flash and 8KB SRAM, providing sufficient resources for embedded PD negotiation and device control logic. With full support for USB 2.0 Device functionality, the board can act as a USB PD sink or source controller, enabling voltage negotiation and communication over USB-C. The board also features rich peripheral support including USART, I²C, SPI, ADC, and multiple timers. Its small footprint and 3.3V operation make it ideal for integration into compact power systems or embedded USB PD evaluation setups. Compatible with WCH-Link debugger and WCH’s IDE, the board is easy to flash, debug, and integrate into larger systems. Whether for learning, prototyping, or developing USB PD applications, this board offers a solid RISC-V-based platform at low power and low cost.
