Firewing for PIC18 is based around a powerful Microchip 8 bit microcontroller that can be clocked at up to 64MHz - with 32KB of ROM (program storage) and 1536 Bytes of working RAM, you will be able to realise many great projects using the free Firewing compiler or any compatible compiler (such as the Microchip "C" Compiler, Swordfish Compiler, Proton Development Suite (PDS) or PICBasic PRO GOLD Compiler)

An easy to use USB interface is provided, enabling you to both program your board and send and receive serial data to and from your PC. The board can be powered from the USB port or by an external supply, providing both 3.3v and 5v supplies for any connected shields or devices.  There are 21 input / output pins, 6 of which can be configured for analog input (ADC) and 2 for Pulse Width Modulation (PWM). Simply plug in some devices and sensors into the sockets or use a dedicated shield to get things going.

The board itself is pin compatible with the Arduino Uno and can be run at both 3.3v and 5v.  For complete Arduino shield compatibility, you should normally run the board at 5v.  If in doubt, drop us an email or use one of  these shields.
