Epson gyroscope XV7001BB, XV7011BB, XV7181BB, XV7021BB, and XV7081BB

Gyroscope sensor, also known as angular velocity sensor. Epson's gyroscope sensor is a sensor component made of quartz material. With its high precision, low power consumption, low cost, and good temperature stability, it is widely used in industries such as floor cleaning robots, AGV logistics robots, automatic lawn mowers, and intelligent driving cars. Epson angular velocity sensors mainly refer to single axis gyroscopes, while six axis gyroscopes are known as inertial measurement units. The Epson gyroscopes XV7001BB, XV7011BB, XV7181BB, XV7021BB, and XV7081BB introduced today are the single axis high-precision gyroscope models mainly promoted by Epson company.

Epson single axis gyroscope model similarities:

External dimensions: All adopt the 5032 (5.0 x 3.2 x 1.3mm) specification, making it more convenient to replace the old gyroscope model with a new model with higher parameters.

Interface: SPI or I2C。 Epson's current main 1-axis angular velocity sensors all support SPI or I2C interfaces.

Power supply voltage: 2.7V~3.6V.

Room temperature deviation: ± 1 (0 LSB Typ.) Both support 16 bit and 24 bit digital outputs simultaneously.
