## Description

The [TFCABxxUART01](https://github.com/ThunderFly-aerospace/TFCAB01) cable is used for data transmission on the Serial links in drones with avionics that conform to the [Pixhawk standard](https://github.com/pixhawk/Pixhawk-Standards/blob/master/DS-009%20Pixhawk%20Connector%20Standard.pdf). The cable is manufactured for high-performance and reliable connections.

The cable utilizes the original JST-GH plastic connectors, ensuring a secure connection between your drone's components. The used color scheme that corresponds to the [ThunderFly](https://www.thunderfly.cz/) color standard described in the [ThunderFly documentation](https://docs.thunderfly.cz/avionics/TFCAB01/#uarttelemserial-cables), you can easily identify the type of bus to expect in the cable, reducing the possibility of incorrect connection.

The wires are made of high-quality tinned copper wires with silicone insulation, ensuring high flexibility and mechanical durability of the resulting cable. The silicone wire is a 26AWG with an outer diameter of 1.0 mm and short-term high-temperature resistance up to 200 °C.

### Important Notes
- **UART cables should be kept as short as possible** to minimize EMI interference.
- **Twisting is not recommended** for UART cables to prevent increased cross-talk.
- **Straight-through wiring**: Ensure that RX/TX and RTS/CTS are properly swapped in device connectors. The cable itself is 1:1.
