## What it is
AxxSolder is an STM32-based open-source soldering iron controller for JBC C115, C210, and C245 cartridges, available as station and portable versions on the same PCB. It runs custom C firmware implementing PID temperature regulation, TFT display, sleep modes, and automatic power limiting from 9-24 VDC or USB-C Power Delivery sources.

## Use cases
- build a DIY soldering station for JBC cartridges
- power a soldering iron from USB-C Power Delivery
- control soldering iron temperature with a PID controller
- make a portable battery-powered soldering iron
- 3D print an enclosure for a custom soldering controller
- automatically limit soldering iron power based on USB-PD supply capability

## When to choose
- you want an open-source, self-built controller for JBC C115/C210/C245 handles
- you need USB-PD or 9-24V DC input with automatic power negotiation
- you want a compact portable soldering iron or a station based on the JBC ADS stand

## When to avoid
- you need a plug-and-play commercial soldering station without soldering/assembly
- you use non-JBC cartridge-style tips like T12
- you don't want to source PCBs, components, and 3D-printed enclosures yourself
