Servo x8 MIC (ME-00045-1A)

ABOUT
The Magzor Servo MIC allows you to control up to 8 servos over I2C. The board has 8 3-pin right angle headers that provide VCC, GND and Signal to individually control your actuators.

POWER
The board accepts 3.3 V input to power the microcontroller and a separate VCC, located on the 4-pin power stacking header, for power to your servo (Note: Keep in mind that VCC will be the same for all lines). The Servo MIC pairs well with the Power Shield MIC for power supply and I2C communication.

CONNECTORS
The board has 8 3-pin right angle headers for connecting devices and two standard MIC stacking headers for power and I2C communication as well as a 3-pin right angle header for programming the microntroller.
 * 8 3-pin right angle headers (2.54 mm pitch): Signal, VCC, GND
 * 1 4-pin Power Header: VCC, 5 V, 3.3 V, GND
 * 1 6-pin I2C Header: GND, SCL, SDA, FLAG, NC, NC

PINS
Each 3-pin header connects to a standard servo connector, providing VCC, GND and the PWM signal for control.
