315MHz 4 Channel RF Transmitter and Receiver Kit IC2262 IC2272 Compatible with Arduino Easy Wireless Control

4Channel 315 MHz Wireless Remote Control Kit (IC2262 IC2272) This kit includes a 4key ASK transmitter and a decoding receiver board based on IC2262 and IC2272. It provides a compact, lowpower wireless switching solution that is easy to integrate with microcontrollers such as Arduino or with relay modules. Key benefits Simple integration: four independent outputs map directly to the four remote buttons for straightforward control in DIY projects and automation systems. Compact receiver: small form factor (6.6 x 22 x 41 mm) fits tight spaces and can be mounted inside enclosures. Low power transmitter: runs from a single 27A 12V battery with only 10 mA operating current, suitable for batterypowered remote use. Reliable signaling: fixedcode encoder with ASK modulation and 315 MHz transmission for basic secure pairings. Direct drive capability: the receiver provides a VT validsignal output that goes when a valid code is received and can be used to drive relays or logic inputs. Main specifications Transmitter Operating voltage: DC 12 V (27A 12 V battery x 1) Operating current: 10 mA @ 12 V Radiated power: 10 mW @ 12 V Modulation mode: ASK (amplitude shift keying) Frequency: 315 MHz Encoder type: fixed code Typical openfield range: 50100 m (range depends on receiver sensitivity and environment; specified with receiver sensitivity 100 dBm) Receiver board Operating voltage: DC 5 V Receiver sensitivity: 98 dB Pinout (7 pins, in ): VT, D3, D2, D1, D0, +5 V, GND VT behavior: VT outputs a signal when a valid code is received; this pin can drive a relay or be read by a microcontroller Outputs: four data outputs D0, D1, D2, D3 correspond to the four remote buttons; pressing a button transmits the code and the corresponding data output goes Size: 6.6 x 22 x 41 mm Package contents 1 x IC2262/IC2272 4channel receiver module 1 x 4key wireless remote controller (for Arduino and general microcontroller use) Typical applications Remote switching for lights or small appliances via relay modules Wireless control for garage gates, gates, or door releases when combined with a relay Wireless input for Arduino projects, remote triggering of sensors, or prototype automation systems Integration notes Receiver requires a stable 5 V supply and common ground with the controlled circuit. Use the VT pin for a consolidated validsignal indicator or to trigger a relay; use D0 through D3 for individual channel state monitoring. Expected transmission distance will vary with obstacles, antenna configuration, and receiver sensitivity; quoted openfield range assumes minimal obstruction. This kit offers a compact, lowpower way to add basic wireless control to electronic and automation projects using standard 315 MHz ASK transmission and a simple fixedcode pairing approach.
