The L3G4200D is a low-power three-axis angular rate sensor able to provide unprecedented stablility of zero rate level and sensitivity over temperature and time. It includes a sensing element and an IC interface capable of providing the measured angular rate to the external world through a digital interface (I2C/SPI).

The sensing element is manufactured using a dedicated micro-machining process developed by STMicroelectronics to produce inertial sensors and actuators on silicon wafers.

The IC interface is manufactured using a CMOS process that allows a high level of integration to design a dedicated circuit which is trimmed to better match the sensing element characteristics.

The L3G4200D has a full scale of ±250/±500/ ±2000 dps and is capable of measuring rates with a user-selectable bandwidth.

The L3G4200D is available in a plastic land grid array (LGA) package and can operate within a temperature range of -40 °C to +85 °C.

I decided to dedicate a POST to the L3G4200D gyro. This popular and low cost sensor is present on a number of multirotors IMU out there. In my case i’ve found this sensor on both models of wich is defined as GY-80 also known as “10DOF 9-axis“, a value for price imu, easy enough except for the pullup resistor needed by this imu in order Read More →

[How to]New 10DOF 9-axis Attitude Indicator L3G4200D ADXL345 HMC5883L BMP085 Module

UPDATED! for pullups resistors correct values! This post is just an update for linking my previous post about 10DOF 9-axis Attitude Indicator L3G4200D ADXL345 HMC5883L BMP085 because this is another name under wich is known.     As you may already know this is an ‘easy to install’ IMU (compared with price) and it could require the addition of two pullup resistors in order to Read More →

Multiwii MWC, Chinese 10DOF (codename GY-80) and Arduino Nano V.3: hooking and testing

Well, i just received my i2c sensors breakout board… Here it is what the Multiwii software configuration file config.h calls GY_80 or GY-80. There is no brand, no model, no serial. We know something just about single main components/chip: (Visited 18,258 times, 16 visits today)
