Hirose DF11-10 pinout
Pin	Func	Pin	Func
1	Vbatt	2	VBatt
3	Reset	4	INTn (MISO)
5	GND	6	SCL (SCK)
7	GND	8	SDA (MOSI)
9	GND	10	GND

This is valid for the version 3 OpenServo.

What is used, and when

When the OpenServo is used in it's normal target application, only the I2C connectors are used (Pins2,6,8, and 10).

However, if the servo is being programmed with a dedicated programmer (i.e. OSIF, STK500, ponyprog, etc.,) the programmer will use pins 2,3,4,6,8, and 10.

NOTE: Pin 6 (SCL) doubles as the SCK line when programming
