Arduino Uno R4

One of the most popular microcontroller boards around, the Arduino Uno launched all the way back in 2010 and the Uno R3 (revision 3) has been the standard for more than ten years. So it was big news yesterday when, as part of its Arduino Day live stream, the company announced the upcoming Arduino Uno R4 board, which will offer huge leaps forward in processing power, RAM, storage and connectivity.

Due out in May for an as-yet-undisclosed price, the Arduino Uno R4 will be available in both "Minima" (regular) and Wi-Fi versions. The wireless version will have an Espressif S3 module that supports both Wi-Fi and Bluetooth connectivity.
