NXP Semiconductors QN9080-DK

Overview

QN9080-DK from NXP Semiconductors is a Bluetooth Low Energy (BLE) development kit centered on the QN9080 SoC, featuring integrated ARM Cortex-M4F MCU, BLE radio, protocol stack, and MIFA antenna. It includes USB dongle, CMSIS-DAP debugger (LPC4322), Arduino- and PMod-compatible headers, RGB LED, and configurable jumpers for power, UART, I2C, and ISP mode - enabling rapid BLE firmware evaluation and current-consumption testing.

For engineers reviewing the QN9080-DK datasheet, QN9080-DK pinout, QN9080-DK application, or QN9080-DK equivalent, this board supports on-board/off-board JTAG/SWD debugging, USB-to-UART bridging, RF conformance testing via Murata RF connector, and precise current measurement using MAX9634T + ADC122S021 with 150 µA lower limit.

Technical Context

The QN9080-DK integrates an LPC4322 microcontroller acting as a dual-role CMSIS-DAP/J-Link bridge and USB-to-UART converter, directly interfacing with the QN9080 BLE SoC via SWD, UART, and I2C paths. Its hardware supports three distinct current measurement methods: on-board analog sensing (MAX9634T + ADC122S021), external ammeter insertion (JP12/JP13/JP14), and DC power analyzer direct supply.

Board-level configuration is managed through 16 labeled jumpers (JP1–JP16), each controlling discrete functions including target selection (on-board vs. off-board), power voltage (1.8 V or 3.0 V), ISP enablement, USB leakage isolation (JP16), and RF test path routing. The QN9080 module uses HVQFN packaging and features an integrated MIFA antenna with optional Murata RF connector for conducted RF testing.

FAQ

What is the primary function of the QN9080-DK?

The QN9080-DK is a complete development kit for the QN9080 BLE SoC, providing hardware and interface infrastructure to evaluate, debug, and validate BLE firmware, RF performance, and ultra-low-power operation. It includes the QN9080 USB dongle, LPC4322-based CMSIS-DAP debugger, Arduino/PMod expansion headers, and precision current measurement circuitry - all integrated onto a single PCB to streamline BLE product development.

Does the QN9080-DK support both on-board and off-board debugging?

Yes, the QN9080-DK supports both configurations via jumper JP1: when open, it targets the on-board QN9080 module; when shorted, it routes SWD/JTAG signals to the debugger connector for off-board target debugging. JP2 also configures power delivery accordingly - pins 1–2 shorted for on-board power, pins 2–3 shorted to disable on-board power when targeting external devices.

How is current consumption measured on the QN9080-DK?

The QN9080-DK offers three current measurement methods: (1) on-board analog sensing using MAX9634T current monitor and ADC122S021 (usable ≥150 µA), (2) external ammeter insertion via JP12/JP13/JP14 jumpers, and (3) direct DC power analyzer supply to QN_VCC at JP14. Each method requires specific jumper settings documented in Tables 6 and 7 of the DK User's Guide Rev. 1.2.

What role does the QN9080 USB dongle play in the QN9080-DK ecosystem?

The QN9080 USB dongle included with the QN9080-DK serves as a standalone BLE host/peripheral device, controlled via Connectivity QTool over a virtual COM port. It enables interoperability testing between the QN9080-DK board and other BLE devices, supports DTM (Direct Test Mode) for RF validation, and allows firmware updates independent of the main DK board's debug interface.

Can the QN9080-DK be powered by a lithium battery?

Yes, the QN9080-DK supports lithium battery operation for true low-power system validation. To prevent USB data-line leakage, jumper JP16 must be left open. Additionally, resistors R48–R50 (driving the RGB LED) should be removed to eliminate standby current draw from the LED circuit - ensuring accurate sub-mA current measurements during battery-powered operation.
