This homemade extension shield has 3 extension bus & 6x12v powered outputs. The board is designed for Arduino MEGA

DESCRIPTION:

Connector 1 = communication Bus including: - RS485 interface - A serial port (Rx & Tx) - A I2C port (SDA/SCL) Connector 2 = Extension bus including: - 2 GND pins - 2 +5V pins - 12 Digital ports - 4 Analog ports Connector 3= Extension bus including: - 2 GND pins - 2 +5V pins - 8 Digital ports Screw blocks for 6 12v amplified ports (BD139). These powered ports are driven by PWM ports of your arduino.

The module includes: - a thermal detector (LM35) - a diagnotstic LED - a jumper for the RS485 terminator (120E) - A 5V regulator with capacitor.

This module should be powered with 12V PS. It regulates the 5V power for your arduino MEGA board.
