## Notes

* 1% accuracy resistors should be used, though resistances are configurable to calibrate readings
* The jumper in the middle ties v3.3 to ADC reference voltage
* The capacitors are not described in the prototype layout
* Only 3 of the 4 sensor resistors are soldered in the images
* The 4 fan headers in a row should be split in the middle, or possibly re-arranged in a 3 x 2 configuration
