With the exception of the Radio, ISP port and Outputs 1-7, all pin-outs are clearly

indicated on the back of the board.

Pin-outs in boxes

are for ports on the

top of the board.

Very Important Note

RX Inputs

Make sure you connect according to the

pin-outs printed on the board.

The supplied plugs use wires coloured red

for ground and black for Vcc.

So ignore the colours on the two supplied

leads

This problem may be resolved on future

stock :-)

Outputs A1-A7 - Servo/Esc Gnd Vcc A1 . . . A7 Signal Top 3 rows A8 and A0 below that (See original documentation) 'A1' = 'Out1' etc. Input: A0 (can use for airspeed) (Thanks Lars) Gnd Vcc Signal APM 2.

Input: Radio/OSD The Radio/Minim OSD port follows the same pin-out as the GPS Gnd Vcc Rx Tx (Black, Red, Green, Yellow), The supplied plug will go in the right way. This is labelled for the device you are using ie: TX goes to TX on the GPS, or Radio Input: Compass Gnd Vcc (3.3v) SCL SDA HK Compass Make sure you cut the track between the two pads above the RESET label if using external compass Warning: the SDA-trace for the external compass is extremely close to the pads, and also very easy to cut.

(Thanks Lars) Input: GPS Same pin-put and connector as the Radio / OSD Gnd Vcc RX TX Make sure you check your gps connections. Some GPS have Gnd and Vcc on the outside pins. But again the pinouts are for the device and so you connect RX to RX, Tx to TX etc. APM 2.

Input: Power Module Documented as "VI Sense" If you are using the power module (from HK or 3DR) its supplied cable will plug into the 'VI Sense' port correctly. The Red and Black wires go to Vcc, and Gnd as expected. Again the pin-out is clearly printed on the bottom of the board in a square box if you need it. APM 2.
