The infrared decoding and encoding module which leads out the serial port of MCU to connect other devices that need infrared control, and can be used as infrared wireless data communication and data transmission
This relay module is 5V active low. It is a single channel relay interface board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc.
It is a small built-in vibration motor Module. After input 5V current, you can control the ON / OFF or vibration intensity of the motor By digital signal or PWM signal.
