Raytac has advanced the dev kit of bundle offer – WIFI+BLE:
AN7002Q-DB-5340-M with an on-board flash memory(MX25R64) to create easy evaluation for Wi-Fi project developments.
[January 2026 Update]
In this article, we will talk about:
Project WITH External Flash MX25R64(8MB) applied
- Connecting through SPI between nRF5340 module: MDBT53-1M(BLE) & nRF7002 module: AN7002Q(WIFI)
- Connecting through QSPI (XIP) between MDBT53-1M and external memory MX25R64

1. Hardware Set Up
Hardware Kit on hand:
- 1 x Nordic nRF5340-DK: PCA10095(2.0.2)
- 1 x AN7002Q-DB-5340-M
- 1 x IDC Ribbon Wire(J-Link Cable)
- 1 x USB Wire –Type C USB
- 1 x USB Wire-Micro USB
Note: Pease make sure to have both “Nordic nRF5340-DK” and “AN7002Q-DB-5340-M” connected and running during the WIFI+BLE (nRF7002+nRF5340) project development.
Hardware Network:
IDC Ribbon Wire(J-Link Cable): Connect nRF5340-DK to AN7002Q-DB-5340-M
USB Wire –Type C USB: Power supply to AN7002Q-DB-5340-M through USB TYPE-C
USB Wire-Micro USB: Power supply to nRF5340-DK through Micro USB
Schematic diagram of AN7002Q-DB-5340-M can be referenced for design as follows.

*nRF7002 module <- SPI -> nRF5340 module
*MX256R NOR Flahs <-QSPI-> nRF7002 module
!! Important Note:!!
The circuit of SW1(p1.08)/SW2(p1.09)/LED1(p1.06) on AN7002Q-DB-5340-M is NOT COMPATIBLE to Nordic WI-FI Control Pin of swctrl1(p1.08)/host_irq(p1.09)/grant(p1.06).
In this case, if you’re working with external flash MX25R64 for the WIFI project, Please avoid pin SW1/SW2/LED1 usage while LED2(p1.07) remains available as normal usage.
For the PCB design of end product/end device(mounted with AN7002Q & MDBT53 modules), the switch & LED should be configured to be SW1(p0.23)/SW2(p0.24)/LED1(p0.28).
