CH582M Development Board

The CH582M MCU Development Board is a high-performance and compact platform designed for developers working on IoT, BLE, and embedded applications. Powered by the WCH RISC-V4A 32-bit processor, this board supports BLE 5.3 and features a built-in 2.4GHz RF transceiver for wireless communication. It comes with 44kB of Flash memory, 32KB of SRAM, and multiple I/O interfaces, including UARTs, SPIs, PWMs, and GPIOs. Its low power consumption and integrated features like an AES-128 encryption unit, temperature sensor, and RTC make it ideal for applications like wearables, industrial control, and smart devices.
