This is a 3D printer control board based on the ESP32 microcontroller, which comes with built-in WiFi and BlueTooth.

**Work in progress! Do not attempt production using this schematic!**<br>
**Current version: v0.4**<br>
**Problem with I2S stepper stream in Marlin firmware; may result in random pauses during prints**<br>
**Current version: v0.5**<br>

Features:
- Able to use up to 5 stepper drivers: X, Y, Z, E0, and E1.

- Allows the use of a Z-axis probe, such as an inductive sensor, running on the input supply voltage (12V to 24V).
- Physical size of 102mm by 102mm. Mounting holes are 3.5mm in diameter, with centers 4mm from the edges.
- "RESET" button can be used to reset the board.
- Use of jumper pins for TMC stepper driver connections. (**undergoing testing**)
- Firmware controlled fans: case, E0, and E1. These fans can be controlled by firmware, or they can be in the "always on" mode by shorting the respective jumpers.
- Use of jumper pins for TMC stepper driver connections.
- Firmware controlled fans: case, E0, and EXT. These fans can be controlled by firmware, or they can be in the "always on" mode by shorting the respective jumpers.
- EXP3 connector for Creality LCD controller.
- AUX1 connector for use with an external host, such as the closed-source MKS TFT32 (**Untested!!**).

# Jumpers

- VUSB_EN: Leave open for normal operation; only short (close) this jumper if you need to power the board via USB. Note: Powering the board with both PSU and USB may cause unstable operation during heating.
- 5V_SEL: Connect to VIN for normal operation; only short (close) this jumper to VUSB if you need to power the board via USB. Note: Powering the board with both PSU and USB may cause unstable operation during heating.
- PWR_SEL: Connect the middle pin PWR_SEL to pin labeled "12V" if using 12V; connect PWR_SEL to pin labeled "24V" if using 24V.
- CASE_ON: Leave open for firmware-controlled case fan; short (close) this jumper for case fan to be always on.
- E0_ON: Leave open for firmware-controlled E0 hotend fan; short (close) this jumper for E0 hotend fan to be always on.
- E1_ON: Leave open for firmware-controlled E1 hotend fan (if used); short (close) this jumper for E1 hotend fan to be always on.
