The Elektor Uno R4 is like an Arduino Uno but featuring two UARTs, two I²C (IIC or TWI) ports, two SPI ports, 24 GPIOs, eight analogue inputs, nine timers, and more. Based on the B-type of the ATmega328 microcontroller popularised by the Arduino Uno, the Elektor Uno R4 is the 100%-compatible successor to the Uno that the Arduino team failed to design. So we did it for you. Sign up for one (or more) Uno R4's at GroupGets.
