is a 2.4GHz wireless serial port transceiver module that offers an affordable alternative to the NRF24L01 for long-range (up to 120 meters) transparent data transmission MSS Eletrônica
If you have multiple sets of JDY-40s nearby, change the channel and address:
void loop() // Poll remote node 1 setRemoteID(1); Serial.println("STATUS"); // Send a query delay(200); if (Serial.available()) String response = Serial.readStringUntil('\n'); Serial.print("Node1 responded: "); Serial.println(response);
Mode Selection Pin (Pull LOW to enter AT command mode, pull HIGH/Floating for transparent transmission) Hardware Wiring Diagram
: Keep the built-in PCB antenna away from large metal objects, motor shields, or dense wiring to maximize your range.
Imagine building a remote-controlled rover intended to explore a dense backyard garden. Traditional Bluetooth modules like the
might struggle with line-of-sight obstacles or drop the connection if you walk too far away. By switching to a JDY-40, you gain a massive 120-meter range
