The Arduino UNO R4 WiFi merges the RA4M1 microprocessor from Renesas with the ESP32-S3 from Espressif, creating an all-in-one tool for makers with enhanced processing power and a diverse array of new peripherals. With its built-in Wi-Fi® and Bluetooth® capabilities, the UNO R4 WiFi enables makers to venture into boundless creative possibilities. Furthermore, this versatile board boasts a convenient on-board 12x8 LED matrix and a Qwiic connector, offering ample space for innovation and unleashing creativity. This dynamic combination empowers makers to transform their ideas into reality and elevate their projects to unprecedented heights.
- adolph 3y agoThat is a weird combo. Up front it looks like the RA4M1 is the main compilation target and probably has all the IO. Then you have a wifi chip of a different compile target that is faster and more capable in the back. Truely this is the mullet of dev boards. RA4M1 [0] 48MHz Arm Cortex-M4F Core 256kB Flash Memory and 32kB SRAM ESP32-S3 [1] dualcore 32bit LX7, up to 240 MHz Flash up to 8 MB, optional 2 MB PSRAM in chip package 39 GPIOs, rich set of peripherals 0. https://www.mouser.com/new/renesas/renesas-ra4m1-mcu/ https://www.mouser.com/new/renesas/renesas-ra4m1-mcu/ 1. https://www.mouser.com/ProductDetail/Espressif-Systems/ESP32-S3-MINI-1-N8 https://www.mouser.com/ProductDetail/Espressif-Systems/ESP32...
- matthewfelgate 3y agoI concur. I'm not sure why not just buy a ESP32-S3 based board...
- adolph 3y agoAnother bad thing about the s3 is no wifi6. The c6 is the first esp with it.
