🏆 T-Halow 🏆

T-Halow is WiFi Halow, an optimized Wi-Fi solution for iot devices, which has a longer transmission distance while providing the same transmission power of 2.4GHz and 5GHz. T-Halow is equipped with the TX-AH module, which can operate in the 730M-950MHz band, the module can operate in the channel width of 1/2/4/8MHz, and can provide a physical throughput of 150 Kbps to 32.5Mbps.

Project

There are two different versions of T-Halow, which differ in the way they are paired;

It is important to confirm the version of T-Halow you have.

- TIME LINK VIDEO
VER1 V1.0 24-08-23 VERSION1
VER2 V1.0 24-04-16 VERSION2 https://www.youtube.com/watch?v=nM2GE8Imshc

Version 1 and version 2 of T-Halow use the same AT commands.

Regarding the SDK of the TX-AH module, Taixin does not provide detailed API instructions. If you want to compile it yourself, you can use this project. hgSDK

TX-AH model comparison

Module name Front screen distinction Overcertified condition remark
TX-AH-R900P Lower left P9, lower right P9 Can pass FCC/CE certification Supports 860MHz to 928MHz
TX-AH-R900PNR Lower left P9, lower right NR Can pass FCC certification Support 902MHz ~ 928MHz, with 915M Saw to improve receiving performance
TX-AH-R900PNR-860M Lower left 86, lower right NR Can pass CE certification Support 859MHz ~ 894MHz, with 875M Saw to improve reception performance

remark:

  1. The difference between the P series module and the earlier A series module is:

(1) The bottom left screen print of the P series is beginning with P, and the bottom left screen print of the A series is beginning with R;

(2) P series PIN4/5 needs power supply, A series does not;

  1. The module does not have a Shield by default. The name of the module with a shield is suffix-s, where S indicates shield.
