This comprehensive guide covers everything required to master the JDY-40 module with an Arduino, moving from hardware wiring to AT command configuration, and concludes with a robust, real-world communication example. Share public link

The is a versatile 2.4GHz wireless serial transceiver module popular for Arduino projects due to its low power consumption ( 40mA40 m cap A

In this tutorial, I’ll show you how to wire two Arduinos using JDY-40 modules and send data back and forth. jdy40 arduino example best

Как работать с беспроводным модулем jdy-40 и ардуино?

The JDY-40 is a half-duplex, 2.4GHz wireless transceiver module. Unlike the nRF24L01, which requires managing 20+ registers via SPI, the JDY-40 communicates over . To your Arduino, it looks exactly like a wire replacement.

Before writing code, it is essential to understand the pin layout and specifications of the JDY-40 module. Pin Configuration This public link is valid for 7 days

void loop() if (jdySerial.available()) String receivedData = jdySerial.readString(); Serial.print("Received: "); Serial.println(receivedData);

) scattered in the garden, each monitoring soil moisture. By sending simple JSON messages with a "destination ID," only the intended remote node replies, making it feel like a sophisticated, custom-built network. Best Practice Setup Example

When testing with separate battery packs or distinct USB ports on different computers, ensure a physical wire links the GND lines of both Arduinos together. Without a shared reference ground, the TTL logic levels will misinterpret incoming data bits. Conclusion Can’t copy the link right now

For a deeper dive into the AT command sequence and advanced configuration, the detailed AT command set analysis is an excellent resource. If you'd like to explore more, I can provide: A for connecting the JDY-40 to a 5V Arduino Nano .

Connect two separate Arduino boards (Transmitter and Receiver) using the following pinout: JDY-40 Pin Arduino Pin (Uno/Nano/Pro Mini) Do NOT connect to 5V GND Common ground TXD Pin 2 (Software RX) Receives data from JDY-40 RXD Pin 3 (Software TX) Use a 1kΩ resistor inline for 5V Arduinos SET Pin 4 (Digital Out) Controls AT Mode / Data Mode CS Kept permanently low for active state Configuring the JDY-40 via AT Commands
