Frequently Asked Questions
Q: What is the JDY-23 Bluetooth 5.0 BLE Module and what does it do?
A: The JDY-23 is a compact Bluetooth 5.0 Low Energy (BLE) wireless module built around the CC2541 chipset. It operates in slave mode and enables transparent UART serial data passthrough between a microcontroller (such as an Arduino) and a Bluetooth-enabled host device. It measures just 19.6 × 14.94 × 1.8 mm and is available as an SMD component in two variants: JDY-23 and JDY-23A.
Q: What is the difference between the JDY-23 and JDY-23A variants?
A: The JDY-23 is the standard version of the module, while the JDY-23A is an alternate configuration variant. Both are based on the same CC2541 BLE chipset and share the same compact SMD footprint. Please select the variant that best matches your project's requirements when placing your order.
Q: Is the JDY-23 BLE module compatible with Arduino and IoT platforms?
A: Yes — the JDY-23 Bluetooth 5.0 BLE Module is fully compatible with Arduino, Raspberry Pi, ESP32, and a wide range of IoT development platforms. Its standard UART serial interface makes integration straightforward, and its low-energy BLE protocol is ideal for battery-powered and embedded applications.
Q: Can I use this module for wireless serial communication between two devices?
A: Absolutely. The JDY-23 supports transparent serial port passthrough, meaning data sent via UART is wirelessly transmitted over BLE without any additional protocol conversion. This makes it an excellent choice for replacing wired serial connections in prototyping and production embedded systems.
