Portable strip soldering station based on Arduino platform Atmege328p

Supports 65W gallium nitride charger, TypeC interface

Overview

mini-T12 is an open source strip soldering station project hosted by Station B: Licorice Acid Is Not Acid. DCDC-LDO two-stage step-down power supply, the front-stage DCDC step-down, and the latter-stage LDO voltage stabilization. Onboard temperature chip tc1047 for cold junction compensation, 128*32-0.91 inch OLED, rotary encoder, SGM8521 rail-to-rail op amp. Calibrated 4-segment temperature curve fitting can be performed in the menu, using the 3-term temperature curve formula. Demo video: https://www.bilibili.com/video/BV1vf4y1B7Xa

The V2.2pd deception version of the current project has been officially released, supporting 65W gallium nitride charger and TypeC interface, saving volume, and optimizing the DCDC circuit without burning the chip.
