These Simple RF receivers are the easiest way possible to add wireless control, painlessly! There's no programming, configuring or addressing - simply power the receiver with ~5 VDC and press the buttons on our matching RF keyfob remote.
Receiver supply. Adafruit says to power the receiver with about 5 VDC and warns that anything higher than 6 V can damage it.
Power return for the receiver module supply.
Toggle output controlled by the A button. Adafruit states pressing A activates the first output pin, and on the T4 type repeated presses turn that pin on and off.
Toggle output controlled by the B button. Adafruit states pressing B activates the second output pin, and the T4 receiver toggles matching pins on repeated presses.
Toggle output controlled by the C button. Adafruit describes a one-to-one link between remote buttons and the four receiver output pins.
SPI · ~5 VDC recommended; do not exceed 6 V per Adafruit product note · 0 V
Verify supply voltage and logic levels before powering up.
Module pins: VCC, GND. Schematik maps them to your board in the app.
