This board which operates at 433 MHz frequency range is a remote control relay board that can be used in various electronic and robotic boards, systems which requires remote control and again systems which can be operated remotely.
4-CH RF remote control is used to turn ON / OFF four different devices independently. Any of the four outputs can be configured to work independently in either toggle or momentary mode.
MAX7219 is an integrated serial input / output common-cathode display driver, it connects the microprocessor 7-segment digital LED display with 8 digits, you can also connect a bar graph display or 64 independent LED.
With this 4 digit Seven segment display module, you can easily add a 4 number LED readout to your projects. Useful for making a clock, timer, temperature readout, etc. Just connect 2 pins to your Arduino, Raspberry Pi, or other microcontroller and control all of the LEDs serially!
A seven-segment display (SSD), or seven-segment indicator, is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.

Note: For it is metal gearbox gear motor, some of them may have a little noise, and it is normal phenomenon. Different parameters have their different looks. The lower the speed is, the larger the torque is. Please read the parameter table for a reference before buying. Thanks!!!
