Product description: 433 MHz radio module + remote control
Four-channel radio module enabling remote communication with microcontrollers by means of a remote control operating at 433 MHz. Connection of the module is very simple, the digital interface makes it possible to connect the module directly to the digital outputs of most microcontrollers using a contact board or connection wires. The product is compatible with controllers including STM32Discovery, Arduinoand Raspberry Pi. Connectors are popular 2.54 mm goldpin raster strips.
433 MHz radio module + remote control.
Support .
The module is powered using the pins marked as 5V and GND. Guidance Vt changes its state to high when it receives a signal from the remote control. Pins D0 - D3 switches to a high state when the button assigned to a pin is pressed, releasing the button will bring the pin back to a low state. The table below shows the button scorre sponding to a given pin.
