A USB-C powered (up to 100 W) mobile soldering station engineered both for working on the go, as well as stationary setups. While it was especially designed to be compatible with JBC irons, it can operate any iron that uses a thermocouple sensor.
Löti delivers precise temperature control, a compact form factor (fits in a Hammond 1455C802 enclosure), and fully open-source hardware and firmware. Browse schematics, PCB layouts, and firmware on github.com/elagil/loeti.
Hardware
The user interface is kept very simple. An OLED screen shows current and set temperature, power output, and optionally a configuration menu. The only input device is a minimalistic encoder knob that can also be pressed—short or long presses are distinguished.
Firmware
Löti’s firmware is written in Rust, and built on top of the embassy-rs framework.
A core component is the USB power-delivery (PD) protocol stack publicly available on crates.io, which can be used with different USB PD interface ICs. Implement a set of traits for adding support to new chipsets.
A Rugged Enclosure
The custom PCB is designed to fit in a Hammond 1455C802 enclosure, which is modified with a CNC router. This enclosure is small, affordable, very robust, and readily available.
