# YDLIDAR X2L 360° Triangulation Lidar

> YDLIDAR X2L (datasheet: X2) is a low-cost 360° 2D triangulation lidar. It ranges 0.12–8 m at 80 % reflectivity, with 2 cm error within 1 m and 3.5 % to 6 m. It samples at 3000 Hz and spins at 5–8 Hz (6 Hz recommended, PWM on M_CTR) for 0.6–0.96° resolution. One-way 3.3 V UART at 115200 baud on MX1.25-4P, 5 V / 300 mA, Class I 793 nm laser, 126 g, 96 × 60.5 × 50.3 mm.
