JDY-40 2.4GHz Wireless Serial Transceiver Module

The JDY-40 2.4GHz Wireless Communication Module is an ultra-low-power serial transceiver designed to replace messy physical cables in your DIY electronics projects. Utilizing the robust 2.4GHz ISM band, it provides transparent serial data transmission, making it incredibly simple to send and receive data wirelessly between microcontrollers. Whether you are reviewing the datasheet for a custom circuit diagram or downloading Arduino code for a prototype, this module offers a highly reliable, plug-and-play communication link.

Perfect for remote control toys, smart home automation, and wireless sensor networks, the JDY-40 is fully ESP32 compatible and works seamlessly with standard 3.3V microcontrollers like Arduino and Raspberry Pi. When you buy online in India, this module gives you the flexibility of both SMD castellated edges and standard through-holes for easy breadboarding or permanent PCB integration.

Features:

• 2.4GHz ISM Band: Offers stable and fast wireless communication free from standard low-frequency interference.
• Serial Transparent Transmission: Acts like a wireless UART cable; what goes into the TX pin comes out the RX pin on the paired module.
• Ultra-Low Power: Highly efficient sleep and active modes, making it ideal for battery-operated IoT nodes.
• Built-in Antenna: Features a high-performance onboard PCB antenna capable of reaching up to 120 meters in a clear line-of-sight.
• Versatile Mounting: Includes both 2.54mm pitch through-holes and castellated edges for easy surface mount soldering.

Package Includes:

1 x JDY-40 2.4GHz Wireless Communication Module
