Board 1: Arduino Pro Mini 328 - 5V/16MHz
Board 2: GY-521 6DOF MPU6050 Module 3 Axis Gyroscope + Accelerometer
I would like to combine the two boards listed below into one. The boards would be wired in the following:
GY-521: Arduino
Vcc : 3.3v-5v (arduino vcc)
GND: Ground
SCL: A5
SDA: A4
AD0: Ground
INT: Digital 2
Dimensions of combined board: 5cm x 2cm
Mounting holes would need to be near the corners.
Also, I would need the new board to be compatible with the Arduino’s Software for programming.
Please send me a quote on how much you would charge to design such a board, and some of your past work.
Please message me if you need more info/questions.
Have you thought about running the 328 at 3.3 V granted you only get 8 MHz but since the MPU6050 runs at 3.3 V you don't need any further voltage regulation or level shifters. It just keeps the part count lower.
I use far more 3.3 V Pro Mini's running at 8 MHz on permanent builds than anything else because most of the sensors I use run at 3.3V and 8MHz is usually more than enough.
You may need more speed than 8 Mhz and if you do just ignore these errant ramblings.
Thanks

I need the speed of the 16 MHz, thanks for the suggestion though! 
I can do this for you if you have not found anyone yet.
You can check out my past and current projects at WWW.EmbeddedAT.com
Drop me a PM to agree cost etc.
Cheers Pete.
