Description

The nRF52840 BLE module is a complete, certified wireless solution built around Nordic Semiconductor Semiconductor’s flagship system-on-chip. It combines a high-performance 32-bit ARM Cortex-M4F processor with a multiprotocol radio supporting Bluetooth 5’s long-range and high-throughput features. The integrated ceramic antenna eliminates the need for external antenna matching, simplifying PCB layout and reducing the bill of materials for space-constrained designs.

Engineered for power efficiency, the module operates from a wide 1.7V to 5.5V supply, making it compatible with various battery chemistries, including single-cell Li-Po. Its advanced power management subsystem enables deep sleep currents critical for extending product battery life in always-sensing applications. The module’s RF front-end is optimized for reliable connectivity, with programmable output power from +8 dBm to -20 dBm for optimal range versus power consumption trade-offs.

Frequently Asked Questions

How do I power and program the nRF52840 BLE module?

The module operates from a wide 1.7V to 5.5V DC supply, connect VDD and GND accordingly. Programming is typically done via the SWD (Serial Wire Debug) interface using a compatible Segger or Segger debugger. You can develop firmware using Nordic Semiconductor's nRF Connect SDK, Zephyr RTOS, or the Arduino Core for nRF52. The module does not include a USB-to-serial chip; an external debug probe is required for flashing and serial communication.

What is the typical range achievable with the integrated ceramic antenna?

With Bluetooth 5.0's long-range mode (Coded PHY) and the module's +8 dBm maximum output power, a line-of-sight range of up to 500 meters is possible under ideal conditions. For standard 1Mbps BLE, expect a more typical range of 50-100 meters in open air. Range is highly dependent on the surrounding environment, PCB layout ground plane, and potential RF interference from other 2.4GHz devices.

Can I use an external antenna with this module instead of the ceramic one?

No, this specific variant has the RF output permanently matched to its integrated ceramic chip antenna. The PCB trace and matching network are designed exclusively for that antenna. If you require an external antenna connector (like IPEX or PCB trace), you must select a different nRF52840 module variant that exposes the RF pin and includes the appropriate matching circuit for external antenna connection.

What development tools and software are needed to start prototyping?

You will need a SWD debugger (e.g., Nordic Semiconductor's nRF52840 DK, Segger EDU). Install Nordic Semiconductor's nRF Connect for Desktop, which includes the nRF Connect SDK (based on Zephyr RTOS), programmer tools, and Bluetooth stacks. Alternatively, use the Arduino IDE with the Arduino-nRF52 core for simpler sketches. Review the module's pinout diagram to connect GPIOs, SPI, I2C, or other peripherals to your sensors and external components.
