I know this email will reveal me as a newbie…
I have a SEN-07915 which is a Honewell HMC6352 compass sensor with a breakout board. What is included on the breakout board? I see IC components (resistors? capacitors?) connected to Vcc and GND, but I can’t find documentation on what they are.
Thanks for your help!
That’s odd. Usually there is a schematic.
One is definitely a 0.1uf decoupling capacitor which is specified in the datasheet. The other two are probably the pullup resistors for the I2C clock and data lines. The spec sheet gives 10k values, but Sparkfun may have put other values. You can check with a regular multimeter.
