4-Channel 315MHz Remote Control & Receiver Module - Brown

The 4-Channel 315MHz Fixed Code Remote Control & Receiver Module - Brown is a wireless RF remote control set for receiver-based control applications. It uses a 315MHz operating frequency and fixed code encoding. The receiver operates at DC 5V and provides four output channels. The remote uses four buttons, matched to the receiver outputs D0, D1, D2, and D3. The output works in Jog mode, so the output stays HIGH while the button is pressed and returns to LOW when released.

This module set includes a transmitter and receiver board for wireless signal transmission and reception. The receiver board uses ASK modulation and has a valid signal output pin labeled VT. The receiver size is 41x23x7mm. The receiver sensitivity is -98dB. The listed transmission distance is 50m - 100m in an open field. A line-of-sight range of up to 4 meters without an external antenna is also noted. The remote can work with 315 MHz fixed code receivers, and coding requires opening the remote and soldering the coding bases.
