A foreign expert has created a heating temperature control board using the ESP32-C3, complete with schematic and PCB. Those interested can learn from it. The schematic includes the minimum system circuit, USB Type-C interface circuit, 3.3V voltage conversion circuit, heating control circuit, temperature sensing circuit, rotary encoder switch sensing circuit, and display interface circuit. It is suitable for students engaged in consumer electronics to collect and study.
The circuit diagram is as follows. If you need high-definition schematic and PCB GERBER source files, you can join the group to request them, or reply in the official account with: Heating Temperature Control Board
