AxxSolder
AxxSolder is an open source STM32 PCB design by AxxAxx: a 2-layer, 39 × 82.5 mm board with 122 components (44 distinct parts). It is built around the TLV76733DRVR, OPA2387DSGT, LMR54406DBVR, STM32G431CBT6 and more. Filed under power & battery.
STM32 Based soldering station for JBC cartridges, 9-24 VDC and USB-PD power

AxxSolder handles this by alternating between heating and measuring. Forty times a second a timer interrupt turns the heater off, waits 0.5 ms for the signal to settle, and triggers the ADC. The heater is switched back on as soon as the conversion is finished. The measurement window is short compared to the 25 ms between measurements, so very little heating power is lost and the control loop still gets a clean reading every cycle. On a…
