In this video, I show you how I built my own 10-channel thermistor-based voltage logger with some new improvements. The project uses a high-performance STM32F401 microcontroller, an 1.8" TFT LCD with an SD card slot, a button and my custom-designed PCB.

Improvements:
- Updated GUI with bar graphs
- More intelligent file saving on SD card
- More flexible calculations (each fixed resistor can be a unique value)
- Replaced some voltage-divider resistors for better low-temperature linearity
- New front panel with symmetric component placement
