3D printer motherboard circuit design based on ESP32S

Overview

ESP32-based 3D printing motherboard. It uses Marlin firmware, you can visit https://marlinfw.org/ for details. Functional description: 1. The ESP-Helios printer control board has five drivers, two of which are used for dual Z control. 2. ESP-Helios can select different drivers as needed. 3. Only one OLED screen interface (ICC interface) and one encoder interface are reserved on the motherboard, and the pin definition can be set to use the serial screen. 4. With 3 high-power mos. The hot bed can be driven directly. (If the current required by the hot bed is too large, it is recommended to connect a larger MOS). 5. The size of the ESP-Helios PCB is only 80*80, but 5 drive axes are inserted on such a small motherboard.
