Teledatics Brings Open Source Wi-Fi to Its Halo Development Platform

Teledatics, an engineering startup developing IoT and Wi-Fi hardware, has launched its open source Halo TD-XPAH development platform aimed at engineers, makers and electronics enthusiasts looking to bring Wi-Fi 6 to their projects. The board allows for several hundred clients per access point and offers long-range wireless communication abilities up to 1 kilometer (about ½ mile). While Halo supports the 802.11ah protocol, it also enables users to add 802.11s mesh network nodes to increase that distance further.

The Halo TD-XPAH is designed around an AzureWave AW-HM482 module, which is based on the Newracom NRC7292 with Cortex-M3/M0 SoC with 752 Kb of RAM and 2 Mb of Flash. The board comes equipped with a single USB Type-C port for power and programming, as well as three headers with up to four I2C, two SPI, four UART, eight PWM, four nine-bit ADC and 32 GPIO. It also packs six high precision timers, three watchdog timers, a 10-pin JTAG Arm interface (debugging), a real-time clock, and a temperature sensor.

According to Teledatics, the TD-XPAH can be used as a standalone or USB device and provides both the firmware/SDK (nrc7292_sdk) and Linux drivers (nrc7292_sw_pkg) on GitHub, along with a KiCAD 6.x template that lets users create expansion boards.

The company is currently crowdfunding the Halo TD-XPAH on Crowd Supply for $99, along with several HATs for everything from sensors to Ethernet connectivity.
