I found some Eagle files for the MPU6050 which I want to combine into another board to save space. However, looking at the one I bought, I notice they're different - the MPU6050 I bought off EBay appears to have some extra components, most notably the 5-pin IC at the top here:
This is what the board looks like from the Eagle files found on Github:
(EDIT: Schematic also attached, since the board might look visually confusing without it):
Should I be concerned? I don't want to have a prior version manufactured into my board and then find out it has some crippling error or power issue.
EDIT 2: Looking at the official datasheet for the MPU6050 chip, the 'typical circuit' is identical to the one presented in the Eagle file, save for the two pulldown resistors on SDA and SCL (which I assume are only to prevent too much current going into/out of those pins). Still, does anyone have any thoughts on those extra components?
The 5-pin IC seen on the one I purchased is a 4A20 3.3V voltage regulator, which I suppose makes sense - I'm using a buck converter elsewhere in the combined board I'm making for the same purpose (power supply is 2S LiPo coin cells). Still confused by the other extra SMD parts on there - I can see one is a LED, but the others could be either extra resistors or capacitors.
