The OSEPP UNO R4 Plus board is one of the most popular Arduino boards out in the market! This board uses the 8-bit, AVR, RISC-based ATmega328P microcontroller from Microchip (formally Atmel) and offers many improvements over the base Arduino Uno design.
- Four additional 5V and GND power pins.
- Two additional analog pins, A6 & A7.
- Upgraded ATmega 16U2 chipset.
- Powered by either USB or a DC power jack.
- Built-in ICSP (in-circuit serial programming) header for programming the microcontroller.
- Compatible with all Arduino software and hardware made for the Arduino Uno.
