2.4GHz Wireless Switch Module Pair for DIY Projects
Add a low-voltage wireless control link to a compatible electronics project without writing the radio-pairing code yourself. This kit has transmitter and receiver modules. It is for integrators checking the exact channel count, pinout and logic load.
- ✅ Build a wireless switch link — A transmitter and receiver pair are named.
- ✅ Avoid writing the link firmware — Built-in coding and pairing are stated.
- ✅ Reuse the pairing after setup — Initial pairing is retained for subsequent use.
- ✅ Keep the antenna on the board — PCB antennas are specified.
A logic-control module, not a mains switching relay
The availability note names TXH and RX4 regular versions, so confirm actual channel counts rather than assuming the generic six-channel description applies. Check the pinout and signal mode before wiring.
The named supply is DC 2.5–3.6V and output current at most two milliamps. Loads require appropriate interface circuitry; do not connect mains or a motor directly. No guaranteed wireless range is promised.
