Wave UNO R4 Minima Compatible

The Wave UNO R4 Minima Compatible development board is based on the R7FA4M1 32-bit microprocessor, mirroring the design and layout of the Arduino UNO R4 Minima. Powered by Renesas Electronics' Arm® Cortex®-M4 processor, running at 48MHz, it offers enhanced processing power, 256 kB Flash memory, 32 kB RAM, and versatile connectivity features.



With 5V/3.3V headers, a 12-bit DAC, CAN bus, operational amplifier, and multiple onboard LEDs for power and communication monitoring, this board is ideal for flexible development. It supports both USB-C and external power (6-24V) inputs, with solder pads for custom interfaces, making it highly adaptable for various projects.
