Program & Debug Module ( ICD-2 Module with RJ-12 Jack )

4. Components Microchip PIC24FJ256GA110 – 100 pins
GSP uBlox LEA-4P – UART Interface
3Axis Accelerometer – ADXL330 – 3 ATD Outputs
2Axis Gyro – IDG300 = 2 ATD Outputs
Range Finder - MaxSonar-EZ1 – 1 ATD Output
Barometer – SCP1000 – SPI Interface
SD Card Slot – SPI Interface
Receiver Operates using a 5V rail
Everything runs at 3.3V on the Autopilot side
Estimated Total Current Draw for Autopilot ~157mA
