Pro Micro 5V 16Mhz Arduino Compatible Board

It has an ATMega32U4 chip running at 16Mhz with a factory-loaded bootloader. It does not include pins so we can solder only the pins we need. Characteristic: - Microcontroller: ATmega32U4
- Operation: 5V
- Power (max): 5-12V
- Total I / O pins: 20
- PWM pins: 5
- Analog pins: 12
- Maximum current of I / O pins: 40 mA
- Maximum current of pin 3.3V: 50 mA
- Flash memory: 32 KB (4 KB used by the bootloader)
- SRAM: 2.5 KB
- EEPROM: 1 KB
- Speed: 16 MHz
- external interrupt
- TWI / I2C, UART, SPI interfaces
- Dimensions: 18x33mm
- Weight: 30 grams
