The IR Relay Shield utilizes four high quality relays and provides NO/NC interfaces that control the load of high current. Which means it could be a nice solution for controlling devices that couldn’t be directly controlled by Arduino’s Digital I/Os. The onboard infrared receiver allows you to make infrared remote control fan or other smart home project. It can be plugged onto the Arduino UNO R3 / Arduino Mega2560 or the other compatible board and it can avoid the trouble of connecting cable. With an infrared remote controller(with a CR2025 lithium battery). Feature: Can be controlled by infrared remote(38KHz); Standardized shape design for arduino shield; Driven by 5V / 3.3V normally closed contacts open normally closed contact closed; Working status indicators for each relay; 4 x M3 screw mounting holes easy to install; Note: Remove The plastic sheet before you use the infrared remote controller

The expansion board can be used as engraving machines 3D printers and other driven expansion board a total of four slots stepper motor driver module can drive four stepper motor stepper motor and each road only need two IO port that is six IO port can be be well managed three stepper motor very convenient to use say goodbye to traditional stepper motor operation cumbersome. It is noteworthy: stepper motor reverse circle stop one second and then turn around the positive so the cycle. In connector A4988 module when careful not interpolated reversed. Stepper motor wiring is: 2A 2B is a set of (red green) 1A 1B to a set of (blue yellow) wants to change direction change in the position of one group can be for example exchanged with 2A 2B.
