Arduino Uno R3 compatible board. This a board that includes a USB-A connector with Atmega328P processor at a low-cost. It has the same characteristics as the original Arduino Uno board and very similar to other boards such as Arduino Nano, Diecimila, Duemilanove.
- Built-in LED at pin 13.
- Analog inputs A0-A5.
- Green (TX), Red (RX) and Orange (L) LEDs.
- ICSP connector por direct programming.
- USB-A (drivers CH-340).
- 14 I/O pins.
- SPI, I2C.
- Reset button.
