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.Draw out all of the digital I/O mouth and analog I/O mouth, every IO mouth has the positive and negative power supply interface standard Lead the I2C interface on the main board, convenient and connection of the I2C device Increase the DC power supply interface. The NANO plate on the USB interface power supply current is actual only 50 ma, to bring high current equipment such as steering gear, when I was at this time in DC power supply interface provides an external power supply, ensure the stability of equipment operation.
