The Servo Expander allows you to add more servos and write scripts to automate and sequence tasks. It's Arduino based with header pins to easily connect and power servos and other IO devices. It also breaks out the i2c bus to communicate with the main Stealth Controller or other i2c devices.

This is a slighly revised board to now include a power header screw terminal, modified board layout including power LEDs to better indicate where power is being drawn from (i2c bus or PWR)

Connections:

• 12 Servos/Digital IO pins 1-12 (maps to Arduino DIO 2-13)
• 4 Analog IO pins (maps to Arduino A0-A3)
• i2c header/bus (2 connections, each with V,G, SCL and SDA)
• Status LEDs for power connections via PWR or i2c bus
• PWR Screw Terminal (new feature)
• PWR Header (for easy quick connect/testing or low amperage servos)
• Arduino Programming Header (using FTDI Serial cable/adaptor)
