step 1: remove one row of the space
step 2: solder the stackable header (don't add too much solder - keep it flat)
step 3: solder the DC barrel jack (in the new board this is pre-soldered)
step 4: solder-connect the UART pads on the TMC2209 SilentStepStick driver, all 3 pads can be connected but most importantly the top 2 should be connected
step 5: solder header pins to the TMC2209 SilentStepStick driver
(post soldering not shown)
important: populate driver 1, 2 and 4 (instead of 1-3 in the image below)
step 6: connect 12V and adjust V_ref to 0V so there's no current to the motor before the driver is initialized through UART
step 7: solder the male header pin for the z-motor
step 0: solder the AMP mini CT 16 pin connector (ignore for now - to be updated)
step 1: populate the header pins - don't forget the three female headers
step 2: solder the male and female header pins, make sure not to leave any pin out
step 3: mount stackable headers and the 4 spacers
step 4: remove the Arduino (be gentle), stack the processing plane and solder
step 5: connect the Arduino
