- Power supply voltage: 5 V
- Frequency of operation: 315 MHz
- Digital outputs - change of logical state after pressing the key
- Number of buttons: 4
- Range: up to 10 m
- Receiverlayout SC2272
- The remote control is powered by a L1028 - 23 A / 12 V battery (mounted in the remote control)
- Dimensions: 43 x 23 x 7 mm (without connectors)
The set includes: remote control with batteries and receiver module. Holding the button on the remote control changes the logical state on the appropriate output of the receiver. The system is powered by 5 V.
Simple, digital interface makes it possible to connect the module directly to digital outputs of most microcontrollers and sets, including STM32Discovery , Raspberry Pi and Arduino. The connectors are popular goldpin strips (raster 2.54) that allow the chip to be wired or directly connected to a contact board.
The supply voltage should be connected between 5Vand GND pins. The Vt output changes from low to high after each correct reception of the remote control signal. Pins D0 - D3 change to high after pressing appropriate button on remote control. Releasing the button means that the output returns to the previous state - low. The table below shows the connections between the buttons on the remote control and the receiver pins:
In case of short range of the remote control we recommend to solder a piece of wire, as an antenna, to the receiver module.
