|Top-Bottom, SD Card module, RTC/EEPROM module and GY-80 IMU|
The smaller board at the bottom is the really interesting one! It is a GY-80 IMU clone, containing a three-axis gyroscope, three-axis accelerometer, three-axis magnetic sensor and a temperature and pressure sensor, again all accessed simply via the I2C interface. Popular in aeronautical RC and personal UAV projects such as Quadcopters it seemed worthy of some experimentation.
All the devices were purchased from Etang Electronics on eBay and was impressed as it all arrived the day after ordering.
I am using the only proper serial port for the GPS data and I wanted some method of getting debugging and instrumentation from the device during testing. I could have constructed a software serial port but I had an unused LCD character display so decided to connect it up (won't be included on a proper payload!)
It looks nice and is 'cool' however the backlight LEDs do draw an awful lot of current so have been disconnected since the picture was taken.

I have also yet to investigate another transmitter unit I have purchased.
