Flashing

Flash using Tasmota Web Installer and select tasmota32-lvgl option.
For esptool.py download f.e. tasmota32-lvgl.factory.bin and run esptool.py write_flash 0x0 tasmota32-lvgl.factory.bin.

This is only a proof of concept!!! Installing Tasmota does not result in a functioning soldering iron. There is no built in control of the heating element. Drivers for the SparkFun LIS2DH12 accelerometer sensor are missing. Original firmware and source can be downloaded from GitHub

DANGER Heating element is controlled with Power1. This can be dangerous because the soldering tip can overheat very very quickly (10 seconds when powered with 20V).
