KE0003 Arduino I/O Expansion Board

This arduino I/O expansion board provides an easy way to connect sensors, servos and RS485 device to Arduino board. It expands Arduino’s Digital I/O and Analog Input Pins with Power and GND. It also provides separate PWM Pins which are compatible with standard servo connector. Another unique feature is that the I/O shield has a build-in RS485 converter which allows Arduino communicating with RS485 devices. The communication socket provides an extremely easy way to plug a wireless module such as APC220 RF module and DF-Bluetooth module. It has an individual power input for Servos. A servo power jumper allows user to select using external power or internal power to drive the servos.
