Welcome to the Renesas RZA3UL Feather SoM GitHub repository!
Here you'll find all the resources you need to get up and running quickly.
The Renesas RZ/A3UL allows you to achieve the full potential of a real-time operating system (RTOS) while leveraging the performance boost provided by the 64-bit Arm® Cortex®-A55 CPU core with a maximum operating frequency of 1 GHz. Integrating the 512Mbit OctaFlash and 512Mbit OctaRAM we conveniently packaged them in a Feather format.
Besides the processor, the Feather SoM contains the classic Feather features: digital GPIOs, I2C and SPI communication pins, UART pins, a LiPo battery power plug, and the USB programming port. The SoM also features a USB Type-C for powering the board and for USB debug upload.
The pinout for each port is as follows:
