AxxSolder is a STM32 based soldering iron controller for JBC C210 and C245 cartridges. Two different versions are designed around the same PCB and software - one soldering station based on the JBC ADS stand and one portable version. The hardware takes a DC input source of 9-26V. The software is written for the STM32G431KB and implements a PID for temperature control, LCD driver and a sleep function when the handle is at rest. Enclosures for both the station and portable versions are 3D printed.
