Abluetech PTR7002 WiFi 6 and PTR5302 WiFi 6 and BLE 5.4 modules feature Nordic Semi nRF7002/nRF5340 wireless chips

Shenzhen-based Abluetech has launched two low-power wireless modules based on Nordic Semi nRF7002 and nRF5340 wireless chips. The PTR7002 is a dual-band WiFi 6 module based on the nRF7002 chip, and the PTR5302 module combines the nRF7002 with the nRF5340 wireless microcontroller to offer 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 the nRF91 Series cellular IoT Systems-in-Package (SiPs), but it 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 and suitable for home automation, smart lighting, and other loT devices with Matter, Bluetooth LE for commissioning, Thread for low power mesh, and Wi-Fi for high-throughput.

The manufacturer product page has limited information, but 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 sold for $10.97 including shipping.

The PTR5302 can be used as a standalone module thanks to the Cortex-M33 application core and should eventually be found in Smart Home devices, smart lighting, IoT gateways/bridges, wearables products, healthcare devices, and other IoT devices.

The product page has a few more details including a datasheet with the pinout and other information, but nothing about software. You can likely use the same documentation mentioned above for the official nRF7002 DK from Nordic Semi since it’s also based on an nRF5340 + nRF7002 design. The datasheet mentions a PTR5302-EVB with keys, LEDs, and I/O headers, but I was unable to find information about it. The PTR5302 module can be purchased on AliExpress for $15.40 shipped.

Those are the first third-party nRF7002 modules we cover on CNX Software, but the Nordic Semi’s website also lists modules from Fanstel and MinewSemi, besides the Abluetech models discussed in this article.
