A very effective 3-axis gyro board based on the extremely popular Invensense ITG-3200 3-axis Gyroscope.  The sensor address solder switches/jumpers are set to their default addresses by me for your convenience (the addresses the MultiWiii code is looking for), as well as an on-board 5V->3V3 LDO regulator, low power (~2mA) LED, and 2K2Ω pull-up resistors already installed for ease of installation on your end.  Once you receive your sensor board, there are only 4 connections you need to make - 5V, GND, SCL & SDA - nice and easy.  Also, for use in other environments, the sensor interrupt/s have been brought out too.

- PCBs Manufactured in the USA
- Parts Sourced from US Based, Manufacture recommended Distributors

- Assembled in the USA

For mounting purposes, orientation is Y = forward and X = right so you can just un-comment the individual sensors in the config.h file of the sketch.  The parts of the config.h file that need to be modified are as follows:

I2C Speed (Set to 400KHz Fast Mode):
//#define I2C_SPEED 100000L     //100kHz normal mode, this value must be used for a genuine WMP

#define I2C_SPEED 400000L   //400kHz fast mode, it works only with some WMP clones

I2C Pullups (Disable them):
//enable internal I2C pull ups

Sensor Selection:

//if you use independent sensors
//leave it commented it you already checked a specific board above

/* I2C gyroscope */
#define ITG3200
//#define L3G4200D

Mounting Orientation:
