HeaterControl-Shield
🔥 STM32 Shield for Heat Control
HeaterControl-Shield is an open-source electronic board designed to control a heating resistor, measure the consumed current, and detect the temperature near the heating resistor. This board is shaped as an Arduino shield and optimized for use with an STM32 Nucleo.
🎯 Main Features
- 🔥 Heating resistor control via an N-channel MOSFET.
- ⚡ Current consumption measurement using a shunt resistor and an operational amplifier.
- 🌡️ Temperature sensing using a thermistor integrated into a Wheatstone bridge, amplified by an instrumentation amplifier.
- 🛠️ Open-source and customizable design to adapt to specific project needs.
