Arduino I/O Expansion Shield
(SKU: DFR0014)
Introduction
The Arduino I/O Expansion Shield 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.
