Simple PCB

The initial Teensy Fan Controller PCB, designed to fit in a Raspberry Pi 3 case:

Simple 001 PCB in a Raspberry Pi 3 case

Simple002 design files are available, but untested.

Build Instructions

• Order PCB fabrication using the provided Gerber files (fe. 4pcb 33each)
• Order parts using provided bill-of-materials
• Solder parts onto PCB, guided by the provided parts list

Simple 001 board mount holes do not exactly fit the enclosure. Perform these steps to fit the PCB in the enclosure:

• Increase board mount hole size using a 7/64" drill bit

• Remove the in-board portion of the enclosure stand-offs (keeping the majority of each stand-off)

Features

• Supports Teensy 3.x

• Standard 4pin Molex PC power connector

• Fits in a Raspberry Pi 3 case
• 6 fans

• 5 temperature sensors

Simple 001 fan 6 control is not functional when used with a Teensy 3.2.

Notes

• The jumper in the middle (JP1) ties v3.3 to ADC reference voltage

• The AGND-GND bridge (R6) is left open

A 2nd revision--Simple002--will be published, removing the AGND-GND bridge and the V3.3-AREF jumper.
