RSS Bot Posted February 22, 2023 Share Posted February 22, 2023 When we first wrote about the 10-cent CH32V003 RISC-V MCU it was offered in a $7 development board and the closed-source MounRiver Studio IDE had to be used for programming. But things have improved since October 2022, and now, you can buy a CH32V003 board for as little as $1.5 plus shipping, and an open-source GCC toolchain and flasher/downloader are now available. Let’s have a look at the hardware first with the low-cost nanoCH32V003 development board featuring a 48 MHz CH32V003 RISC-V microcontroller with 2KB SRAM and 16KB flash, a USB Type-C port for power, a reset button, and two rows of headers for the GPIOs. MuseLab nanoCH32V003 specifications: MCU – WCH CH32V003F4U6 32-bit RISC-V2A microcontroller up to 48 MHz with 2KB SRAM, 16KB flash (QFN20 package) Expansion – 2x 11-pin headers with up to 18x GPIOs, 1x USART, 1x I2C, 1x SPI, 8-channel 10-bit ADC, 5V, 3.3V, GND Debugging [...] The post CH32V003 RISC-V MCU gets $1.5 development board, open source GCC toolchain and flasher utility appeared first on CNX Software - Embedded Systems News.
