Hello Kris,

I bought a BNO-055 + BMP-280 board from tindie.com and have tried testing it. But I couldn't access the device through I2C. I'm using an Arduino Mega and a logic converter (http://www.amazon.com/3-3V-Logic-Level-Converter-Module/dp/B0100A9TT2/ref=sr_1_11?ie=UTF8&qid=1441505893&sr=8-11&keywords=logic+converter) to use the BNO-055 board.

For codes, I uncommented Wire.begin(); and TWBR=12; lines and commented out Wire.begin(I2c_MASTER, 0x00, 12C_PINS_16_17 ... ); line.

Could you give me any advice about what I should check or what I might be missing?

Thank you, Howard

I found that the problem was the logic converter which I misunderstood its use.

Thanks, Howard
