Overview
The L3GD20 is a low-power three-axis angular rate sensor produced by STMicroelectronics. It integrates a sensing element and an IC interface, enabling the measurement of angular rates around the roll (X), pitch (Y), and yaw (Z) axes. The sensor utilizes a dedicated micro-machining process for the sensing element and a CMOS process for the IC interface, ensuring high integration and precision. The L3GD20 is designed to provide angular rate measurements through a digital interface, supporting both I2C and SPI protocols. It is available in a plastic land grid array (LGA) package and operates within a wide temperature range of -40 °C to +85 °C.
