# LeddarOne Lidar
|
|
|
|
[LeddarOne](https://leddartech.com/solutions/leddarone/) is small Lidar module with a narrow, yet diffuse beam that offers excellent overall detection range and performance, in a robust, reliable, cost-effective package.
|
|
It has a sensing range from 1cm to 40m and needs to be connected to a UART/serial bus.

|
## Hardware Setup
|
|
|
|
LeddarOne can be connected to any unused _serial port_ (UART), e.g.: TELEM2, TELEM3, GPS2 etc.
|
|
|
|
Build a cable following your board and pinout and LeddarOne pinout (shown below). You only will need to connect 5V, TX, RX and GND pins.

|
|
| 4 | RX |
|
|
| 5 | TX |
|
|

|
|
|
|
## Parameter Setup
|
|
|
|
[Configure the serial port](../peripherals/serial_configuration.md) on which the lidar will run using [SENS_LEDDAR1_CFG](../advanced_config/parameter_reference.md#SENS_LEDDAR1_CFG).
|
|
There is no need to set the baud rate for the port, as this is configured by the driver.
|
|
|
|
::: info
|
|
If the configuration parameter is not available in _QGroundControl_ then you may need to [add the driver to the firmware](../peripherals/serial_configuration.md#parameter_not_in_firmware):
|
|
|
|
```plain
|
|
CONFIG_DRIVERS_DISTANCE_SENSOR_LEDDAR_ONE=y
|
|
```
|
|
