MuseLab nanoCH32H417 – A $17 WCH CH32H417 RISC-V MCU development board with USB 3.0, Fast Ethernet

nanoCH32H417 Development Board with Displa

Designed by MuseLab, the nanoCH32H417 is a development board for the WCH CH32H417 dual-core RISC-V MCU, which we covered earlier this year for its USB 3.0 (5 Gbps), UHS, and Fast Ethernet support. At that time, only the official CH32H417 development board was available, but this board adds a third-party option. The board exposes various features of the MCU, including one USB 3.0 port, two USB Type-C ports, a 100Mbps Ethernet interface, and a MicroSD card slot. It also simplifies the prototyping workflow by integrating a WCHLink-E debugger directly onto the board, meaning you won’t need to wire up an external programmer to flash the MCU or view serial output. MuseLab nanoCH32H417 specifications: MCU – WCH CH32H417QEU6 MCU QingKe RISC-V5F up to 400 MHz QinKe RISC-V3F up to 144 MHz GPU – Graphics Processing Hardware Accelerator GPHA Memory – 896KB SRAM Storage – 960KB Flash Storage – MicroSD card slot Display […]

WCH BLE Analyzer Pro USB Bluetooth LE sniffer gains Linux software with Wireshark (pcap) support

Last November, we wrote about the WCH BLE Analyzer Pro, an inexpensive (~$20) USB Bluetooth LE sniffer and analyzer, which looked useful and good value for reverse engineering and debugging. One downside is that the WCH BLE Analyzer software was only made for Windows 7 to 11, but Xecaz decided to look into it and reverse-engineered the USB protocol to write Linux software using libusb that outputs a standard pcap compatible with popular tools such as Wireshark, or as he puts it: “WinChipHead forgot to ship a Linux driver. We forgot to ask permission.” As a reminder, the BLE Analyzer Pro features three CH582F Bluetooth LE RISC-V microcontrollers and a CH334 USB hub, supports Bluetooth Low Energy (BLE) 4.0/4.2/5.0, and connects to the host through its USB-C port. The Linux “driver” for the BLE Analyzer Pro tool can be found on GitHub. Building and installing the software is quick and […]
