Picked up a soldering station with H/W Ver 2.1S and S/W 2.10 from KSGER store on Ali. Build quality is very good, price was high.
The handle has a NTC thermistor inside that doesn't seem to do anything.
What do your station do?
Bottom right corner of OLED shows a temperature 40°C all the time. Even with a handle plugged in or not, or shorting the "N" pin to GND.
Menu 04. Cold End Adj. -> NTC-> 40°C {dial in}
The temperature I dial-in is always displayed.
I drew a full schematic of the controller board and 24VDC power supply.
The NTC input is just a pullup resistor going to the MCU input. So the hardware seems fine, it must be crappy firmware?
RTC battery was DOA and a new one also died quickly. Took out the stupid resistor R10 from this video: https://www.youtube.com/watch?v=B-xWhPcr6jk
