The PIC a'duino uses the Microchip PIC 16F887 - 44pin TQFP device with 36 pins of I/O and the FTDI chip for serial USB output as a com port.
Physical
- Board Size 80mm x 55mm ('Arduino Uno' is 70mm x 55mm)
- Mounting holes same as the 'Arduino Uno' (measured from left hand edge)
Power connections - (as per 'Arduino Uno') +3.3V, +5V, GND, +Vin
Analogue Inputs - 6 inputs (A0 to A5) - these pins can also be configured as general purpose Digital I/O. An analogue GND and Reference are available.
Digital I/O - 14 Pins (0 to 13) with 0 & 1 as Rx & Tx respectively, PWM available from pins 3, 5, 6, 9, 10 & 11
Interrupt button
Serial USB I/O USB connector mini B
I2C connection on Digital Pins 11 & 13 (see note on compatibility).
Additional Features
- Piezo Sound - jumper selectable
- Analogue voltage input potentiometer
- 8 LED indicators - jumper selectable, provide binary output display from PORT D
- 3 digital I/O pins (with Pwr & GND) for direct connection to various sensors - 0.1" pitch
- 2 analogue I/O pins (with Pwr & GND) for direct connection to various sensors - 0.1" pitch. (These can also be used as general purpose digital I/O).
- LCD Display connector for the Hitachi HD44780 style display - end connectors DIL version - a 16 character by 2 line display is included with the package. This connection will also take a 14 pin IDC (Insulation Displacement Connection) socket which enables a ribbon cable connection to other displays. The LCD connector uses additional pins from the PIC leaving all standard analogue and digital connectors available for various shields
- ICSP - In Circuit Serial Programming connector - mates with Microchip PICkit 2 (optionally the PICkit 3) serial programmer / debugger as the hardware interface for Microchip's Professional IDE MPLab®
