Microduino: An Arduino clone nearly as small as a quarter, for $20 Arduino Uno capabilities divided into two small boards for extreme portability.

The UNO R4 WiFi features Wi-Fi and Bluetooth Low Energy connectivity, while the UNO R4 Minima provides a cost-effective option for those seeking the new microcontroller without additional features.

On the surface, it looks like another Arduino UNO clone. But instead of a CPU, it contains an Intel MAX10 FPGA that runs a softcore AVR processor. Of course, that’s only part of the story.

For beginners learning to program Arduinos, a web-based, fully networked developer environment called Codebender could drastically reduce the learning curve.
