Lilygo T-Halow WiFi HaLow Entwicklungsboard 859-894MHz

This board combines the range of WiFi HaLow with the power of the ESP32-S3 microcontroller. The integrated TX-AH module operates in the sub-GHz range from 859 to 894 MHz and can achieve a range of up to 1.2 km with an external IPEX antenna connector, depending on environmental conditions. The ESP32-S3 features two Tensilica LX7 cores with a clock speed of up to 240 MHz, additionally supports 2.4 GHz WiFi 4 and Bluetooth 5 LE, and includes 16 MB of Flash and 8 MB of PSRAM. The module is compliant with 802.11ah, operates with channel widths of 1, 2, 4, or 8 MHz, and achieves data rates between 150 kbit/s and 32.5 Mbit/s.

Note for operation in Switzerland: The operation of this module in Switzerland is only permitted within the frequency range of 863 – 868 MHz. This range corresponds to the license-free SRD band (Short Range Devices) according to the regulations of the Federal Office of Communications. Please ensure that the device is set to this frequency range in the firmware or via AT commands and does not exceed the maximum transmission power of 25 mW ERP. Frequencies outside this range (e.g., 859 – 863 MHz or 870 – 894 MHz) are not permitted for operation in Switzerland as they are reserved for mobile services.
