The RA2E1 Fast Prototyping Board comes equipped with an R7FA2E1A93CFM microcontroller and is an evaluation board specialized for prototype development for a variety of applications. It has a built-in emulator circuit equivalent to an E2 emulator Lite so you can write/debug programs without additional tools. In addition, with Arduino Uno and Pmod™ interfaces included standard and through-hole access to all pins of the microcontroller, and so on, it has high expandability.

Sample software is available to demonstrate the functionality of the RA2E1 MCU and for connecting between the RA2E1 Fast Prototyping Board and various wireless modules or various sensor modules.

Please use Bluetooth®, LoRa® and Wi-Fi according to the radio regulations of each country during use.
