I have found that the MPU-6050 accelerometer sensitivity is half that stated in the datasheet for all ranges; i.e. 1g output is ~1024, ~2048, ~4096 and ~8192 for ranges 16, 8, 4 and 2 g respectively. This is the case for two parts I have tested. To make things more confusing, the accelerometer outp...

Hello I've designed a board with the HMC5883L sensor but I've a problem with the low ESR caps. What caps (manufacturer/esr/voltage rating) did you use for your HMC5883L boards? I can't find any hint about the needed values beside the 4.7µF 0.22µF value and the 0.2 Ohm ESR. But what about the voltage...

Hello! I also cleared the bootloader and now try to get it back. Has anyone succesfully done this? I programm my breakout board over SPI with the use of a buspirate and a self written processing software which is very slow but working. Where do I have to programm the bootloader? Do I have to set som...
