# LeddarOne Lidar
LeddarOne (opens new window) 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.
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.
