Petros CH32H417M Alef Breakout - Dual RISC-V Core & USB3.0 MCU Board
Overview
CH32H417 is a 32-bit microcontroller developed by Nanjing Qinheng Microelectronics, designed for embedded product development. It features USB3.0 high-speed interface and dual-core RISC-V architecture. Leveraging these advantages, XPU Laboratory has launched the Petros CH32H417M Alef development board.
This board adopts the CH32H417MEU6 microcontroller packaged in QFN88 form factor. Measuring 52mm × 21mm, it boasts a compact size and pin-compatible layout with Raspberry Pi RP2040 Pico. Equipped with a USB3.0 Type-A female port, it supports the development of high-speed USB3.0 devices. Actual tests show its downstream transmission speed reaches 430MB/s, making it ideal for high-speed data acquisition. On-board board-to-board connectors bring out DVP, I2C, SPI and ADC interfaces for convenient connection with various sensor modules.
