LeddarOne Lidar

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.

Pin	LeddarOne
1	GND
2	-
3	VCC
4	RX
5	TX
6	-

Parameter Setup

Configure the serial port on which the lidar will run using SENS_LEDDAR1_CFG. There is no need to set the baud rate for the port, as this is configured by the driver.

:::note If the configuration parameter is not available in QGroundControl then you may need to add the driver to the firmware:

CONFIG_DRIVERS_DISTANCE_SENSOR_LEDDAR_ONE=y
