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.
