Ratings and limits
| Operating voltage | 5 V |
|---|---|
| Input voltage | 7–12 V recommended on VIN (pin 30), 6–20 V limits |
| USB | Mini-B, through a Schottky diode (the 5 V rail sits near 4.7 V on USB) |
| Current per I/O pin | 20 mA recommended, 40 mA absolute maximum |
| 3V3 pin | about 50 mA (from the USB-serial chip) |
| Flash / SRAM / EEPROM | 32 KB (2 KB bootloader) / 2 KB / 1 KB |
| Clock | 16 MHz |
| PWM | pins 3, 5, 6, 9, 10, 11 |
| ADC | 8 inputs, 10-bit; A6 and A7 are analog only |
| Size | 45 × 18 mm, breadboard friendly |
How to use it
The same chip as the Uno on a breadboard-friendly board. Many clones use the CH340G USB chip and the old bootloader: if uploads fail with “not in sync”, choose Processor → ATmega328P (Old Bootloader).
