The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore - just enough for most simple projects.
METRO is the culmination of years of playing with AVRs: we wanted to make a development board that is easy to use and is hacker friendly.
This version of the METRO 328 comes as a fully assembled and tested development board but without any headers or the DC jack attached. We do include these parts so that you can solder on if you like, or you can solder wires or header directly to the breakout pads. We also include 4 rubber bumpers to keep it from slipping off your desk.
- ATmega328 microcontroller with Optiboot (UNO) Bootloader
- USB Programming and debugging via the well-supported genuine CP2104
- Input voltage: 7-9V (a 9VDC power supply is recommended)
- 5V regulator can supply peak ~800mA as long as the die temp of the regulator does not exceed 150*C
- 3.3V regulator can supply peak ~150mA as long as the die temp of the regulator does not exceed 150*C
- 5V logic with 3.3V compatible inputs, can be converted to 3.3V logic operation
- 20 Digital I/O Pins: 6 are also PWM outputs and 6 are also Analog Inputs
- 6-pin ICSP Header for reprogramming
- 32KB Flash Memory - 0.5K for bootloader, 31.5KB available after bootloading
- 16MHz Clock Speed
- Compatible with "Classic" and "R3" Shields
- Adafruit Black PCB with gold plate on pads
- 53mm x 68.5mm / 2.1" x 2.7"
- Height (w/ barrel jack): 13mm / 0.5"
- Weight: 16.5g
