RA4M1-Zero Mini Development Board

A tiny way to play with the RA4M1 microcontroller from Renesas - the same chip used on the Arduino UNO R4! Waveshare have created this compact USB-C dev board for small projects requiring the grunt of the RA4M1, a 32-bit ARM Cortex-M4 architecture MCU which runs at 48MHz with built-in FPU (Floating Point Unit), equipped with 256KB flash memory, 32KB SRAM, and 8KB EEPROM. Power and programming are handled via USB-C, which has BOOT and RESET buttons on either side of it. Waveshare also managed to cram an RGB LED into the centre of the board, giving you an option for program feedback (or just some pretty blinky blinky fun!). The board runs at 3.3V by default. Technically, you can move an SMD resistor to set it to 5V instead, but you'll need some serious soldering/reflow skills and gear to achieve that without making a mess of things!
