Revolutionizing DIY Electronics: AxxSolder KiCAD Project
AxxSolder is a groundbreaking project centered around STM32-based soldering iron controllers compatible with JBC C115, C210, and C245 cartridges. It boasts two versions based on the same PCB and software: a soldering station designed for JBC ADS stands and a portable variant. The hardware supports DC input of 9-24V or USB-C Power Delivery. Utilizing the STM32G431CBT6, the software implements PID for temperature control, TFT display driver, and sleep functionality when the handle is idle, along with read/write user settings to flash. Enclosures for both versions are 3D printed, and design files are available under /CAD. The project provides extensive documentation, including a bill of materials (BOM) with component prices. AxxSolder fosters community engagement and support through Discord for build-related inquiries and general questions.
Key Features
- Tip temperature control via a rotating encoder, with sleep mode activated by pressing the encoder button.
- Compatibility with JBC C115, C210, and C245 cartridges, with automatic adjustment of max output power based on handle type.
- Standby mode activated when the handle is placed in the stand or against an aluminum plate on the portable version.
- Safety features include automatic entry into sleep mode after prolonged idle time and overheating protection.
- User settings stored in non-volatile flash memory, configurable via a settings menu displayed on the TFT display.
- TFT display provides real-time information on set temperature, actual temperature, power level, input voltage, MCU temperature, and detected handle type.
