The AxxSolder and AxxSolder Transportable Are 3D-Printable STM32-Powered Good Soldering Stations



Maker Axel Johansson has designed a pair of programmable soldering stations, constructed round an STMicroelectronics STM32 microcontroller and suitable with JBC C210 and C245 cartridges: the AxxSolder household.

“AxxSolder is an STM32 based mostly soldering iron controller for JBC C210 and C245 cartridges,” Johansson explains of their creation. “Two totally different variations are designed across the similar PCB and software program: one soldering station based mostly on the JBC ADS stand and one moveable model. Enclosures for each station and moveable variations are 3D printed.”

Each the full-size and extra compact moveable variations of the AxxSolder station use an STMicro STM32G431KB microcontroller which acts as a proportional–integral–spinoff (PID) temperature controller and drives an OLED show with rotary knob because the system’s consumer interface — providing the power to set a temperature, see the tip’s present temperature, monitor energy draw over time as a bar graph, and even learn the ambient temperature.

“The AxxSolder goes into sleep mode when the soldering iron just isn’t used,” Johansson provides of the station’s bonus characteristic. “This occurs when the deal with is positioned within the soldering iron holder or is in touch with the cartridge pull-out bracket on the station. On the moveable model an aluminum plate is mounted and permits the AxxSolder to enter sleep when the cartridge or deal with rests towards it.”

Each fashions use the identical handles and cartridges, and differ solely in how a lot room the enclosure takes up. Each run on 9-26V DC inputs, making them suitable with a variety of energy sources — with Johansson utilizing 12 Samsung INR18650 35E cells in a 3S4P configuration for a fully-portable mains-free soldering station.

Johansson has launched design information and supply code for each AxxSolder variants on GitHub below the reciprocal GNU Common Public License 3.
