# TFSIK01 Telemetry Modem
|
||
|
||
The [TFSIK01](https://docs.thunderfly.cz/avionics/TFSIK01/) is a high-performance open-source telemetry modem developed by [ThunderFly](https://www.thunderfly.cz/).
|
||
It is designed to provide robust wireless communication between UAVs and ground stations.
|
||
Featuring dual antenna diversity, strong interference immunity, and compatibility with MAVLink framing, it is an ideal choice for demanding UAV and robotics applications.
|
||
|
||
|
||
|
||
The modem is plug-and-play with flight controllers using a JST-GH UART interface and is available pre-configured for the 433, 868, and 915 MHz bands, (other non-standard frequencies available on request).
