Anjielo TXW81X: Bluetooth & Wi-Fi Audio/Video SoC (Wi-Fi Series) — Low Power

Overview: Optimized as a Wi-Fi solution for IoT devices, the TX-AH-R900Pxx series modules—designed by Taixin Semiconductor—are industry-leading Wi-Fi modules compliant with the IEEE 802.11ah standard. The TX-AH-R900P series modules integrate the 802.11ah SoC (TXW83xx); operating within the 730 MHz to 950 MHz frequency band, this chip offers a significantly longer transmission range compared to 2.4 GHz and 5 GHz Wi-Fi at equivalent transmit power levels. The modules support channel bandwidths of 1, 2, 4, or 8 MHz, delivering physical throughput ranging from 150 Kbps to 32.5 Mbps, thereby accommodating a wide spectrum of applications—from low-data-rate sensors to multi-stream, high-data-rate surveillance cameras.
The TX-AH-R900P series modules interface with application processors via various interfaces—including USB, SDIO, SPI, and UART—making them suitable for deployment across diverse fields such as wireless security, drone video transmission, smart homes, and smart grids. Furthermore, the TX-AH-R900P series modules feature an RMII interface, enabling a cost-effective solution for implementing single-module wireless bridges. The modules support both AP and STA modes, facilitating one-to-many networking configurations.
