Initial prototype of modified hartk AfterBurner Toolhead PCB - added an ADXL345 and support ckty on the back side, for a permanently mounted accelerometer on the toolhead.

The front side is the traditional hartk approach, except using a PT1000 for ‘chamber temp’ sensor, added a bypass jumper to the ABL sensor diode (went with a SMD Schottky diode vs. BAT85), and an 18pin IO connector to handle the additional signals for the SPI i/f to the accelerometer. Back side is the accelerometer goodness - basically adapted the adafruit design.

Breakout Board for Alps Alpine RKJXT1F42001 Rotary Joystick, with DNL’d PUs/PDs.

I ordered my stock of these units from RS Electronics EU as there were no US distributors with stock at the time. Looks like Mouser has since received stock after I ordered: RKJXT1F42001 @ Mouser

One note on the symbol/footprint available from Mouser, Pin 11 (footprint ref desig D_2, iirc) is for the positioning lug that is molded into the housing on the RJS and has no electrical connection. The datasheet footprint suggests a 1.1mm diameter hole is needed. The footprint I downloaded from Mouser, iirc, provides for a 1.0mm hole. I manually edited the footprint to make it a 1.1mm hole. Will update this if it proves to be not needed, or if other needed changes are discovered after the board gets stuffed.
