# ESC wiring and connections
## Wiring Diagram
1. BLDC Motor phases (3)
2. Lipo Power Supply +
3. Lipo Power Supply - (GND)
4. Signal/Telemetry reference ground (GND)
5. Telemetry Signal (KISS TLM / SPort / CRSF TX / HOTT / Sensorbus)
6. PWM/Dshot Signal input (PWM / OS128 / OS42 / DSHOT 600-2400)
7. Solder jumper for changing motor direction
8. RX for FTDI connection (Serial CLI)
9. TX for FTDI connection (Serial CLI)
## Connecting KISS ESC to Remote Control RX
> You may use KISS ESC's on a plane or rover without the need of a flight control.

## Motor spin direction
{% hint style="warning" %}
This needs to be done only if you are NOT using DSHOT! \
KISS FC's as well as BetaFlight based FC's do support change of the motor spin direction via GUI / CLI command.
{% endhint %}
On delivery JP1 (7) is open. If a change of direction of motor rotation is desired, the jumper can be closed. Close the jumper by adding solder to the pads → building a solder bridge

# Agent Instructions: Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter:
```
GET https://flyduino.gitbook.io/kiss-documentation/english-kiss-docu/kiss-esc-25a/esc-wiring-and-connections.md?ask=
```
The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
