Shenzhen-based Abluetech has launched two low-power wireless modules based on Nordic Semi’s nRF7002 and nRF5340 radio chips. The PTR7002 is a dual-band WiFi 6 module based on the nRF7002 chip, while the PTR5302 module combines the nRF7002 with the nRF5340 radio microcontroller to provide dual-band WiFi 6 and Bluetooth LE 5.4 connectivity.

The PTR7002 WiFi 6 module is designed to interface with Nordic Semi’s nRF52 and nRF53 series wireless SoCs and nRF91 series cellular IoT system-in-package (SiP), but can also be used with other microcontrollers or application processors with a spare SPI or QSPI interface.
The PTR7002 module and nRF7002 WiFi 6 chipset are optimized for low power consumption and are suitable for home automation, smart lighting and other IoT devices with Matter, Bluetooth LE for commissioning, Thread for low-power mesh, and Wi-Fi for high throughput.
Although the manufacturer’s product page has limited information, Nordic Semi’s developer website has plenty of resources to get started with nRF7002 software development. I first found the PTR7002 module on AliExpress, where it is for sale. $10.97 including shipping.

Thanks to its Cortex-M33 application core, the PTR5302 can be used as a standalone module and will eventually be found in smart home devices, smart lighting, IoT gateways/bridges, wearables, healthcare devices and other IoT devices.
The product page provides further information, including a datasheet with pinout and other information, but no information on software. Nordic Semi’s official nRF7002 DK is also based on the nRF5340 + nRF7002 design, so you might be able to use the same documentation as above. The datasheet mentions a PTR5302-EVB with keys, LEDs and I/O headers, but I couldn’t find any information on it. The PTR5302 module is: $15.40 with shipping on AliExpress.
These are the first third-party nRF7002 modules we’ve covered at CNX Software, although Nordic Semi’s website also lists modules from Fanstel and MinewSemi, in addition to the Abluetech models discussed in this article.
