L3G4200D 3 Axis Digital Gyroscope with Voltage Regulator

Introduction

L3G4200D is a 3 Axis ultra stable digital gyroscope. It gives unprecedented stability of zero rate level and very good sensitivity over temperature and time. L3G4200D module features an on board low drop out voltage regulator which takes input supply in the range of 3.6V to 6V DC. Board has two mounting holes. All 9 pins of the module are arranged in single line. This gyroscope can be interfaced with the microcontroller over I2C or SPI interface. The L3G4200D has user selectable full scale of ±250, ±500, ±2000 degrees per second and is capable of measuring rates with a user-selectable bandwidth.

Interfacing Examples

Case 1: I2C interface between L3G4200D and 3.3V microcontroller.

Note:
1. SA0 pin is internally pulled up to VIO which sets LSB of I2C address as 1.
2. CS pin is internally pulled up to VIO which enables I2C mode.
3. 3V3OUT is capable of delivering 3.3V@ 40mAmps. It can be used set up pull ups for I/O pins related to L3G4200D. It should not be used for other purposes.

Case 2: SPI interface between L3G4200D and 3.3V microcontroller.

Note:
1. 3V3OUT is capable of delivering 3.3V@ 40mAmps. It can be used to set up pull ups for I/O pins related to L3G4200D. It should not be used for other purposes.

Case 3: SPI interface between L3G4200D and 5V microcontroller.

Note:
1. 3V3OUT is capable of delivering 3.3V@ 40mAmps. It can be used to set up pull ups for I/O pins related to L3G4200D. It should not be used for other purposes.
