Features:
- very compact - will fit into handle
- display show status, preset and tip temperature, power, supply voltage, drop, ...
- two buttons
- automatic standby
- sensing supply voltage and tip current
- precise regulation with PID (PSD controller with some modifications)
- supply voltage is from 5V to 18V (best is 10-13V)
- designed to supply from LIPO battery 2S (7.4V max is about 18W) or 3S (11.1V max is more than 40W)
- calculating consumed Wh
- heat-up in 5sec from 25 to 400°C (with 40W limit)
- Idle current about 8mA
What is planed:
- case
- battery monitor (warn when battery need charge)
- configuration editor for some constants from PSD controller, power limit, ....
- open-source everything

Hi, I made myself a soldering iron based on your pcb. It works nicely! Do you know if it is possible to use Weller RTW SMD tweezers with this design? (I was wondering this because of this project: https://hackaday.io/project/171848-soldering-rt1 that you might already know)
