Compact control with built-in wireless
The FYSETC E4 board centers on the powerful ESP32 microcontroller featuring built-in Wi-Fi and Bluetooth. This integration allows direct printer management across any web browser, removing the need for additional hardware like Raspberry Pi. Its compact 90mm x 67mm size makes it ideal for modern 3D printers.
Advanced stepper drivers for smooth motion
Equipped with four Trinamic TMC2209 drivers, the board provides ultra-quiet operation with efficient heat dissipation and up to 2A current capacity. Sensorless homing functionality enables precise and maintenance-free axis calibration.
- Quiet and powerful stepper control
- Large heat sinks for effective cooling
- Support for sensorless homing on X, Y, and Z axes
High-voltage Z-probe support
Unlike boards powering probes at 3.3V or 5V, the FYSETC E4 supplies Z-axis probes with the main input voltage (12V or 24V). This ensures inductive or capacitive sensors operate effectively at their designed voltages, improving detection reliability.
- Dedicated Z probe connector
- Power supplied at 12V or 24V depending on power input
- Improves probe detection performance
Flexible antenna options
Choose between a built-in Wi-Fi antenna or an external antenna version. The external antenna is ideal for enclosed setups where signal strength may degrade, ensuring stable wireless connectivity.
- Onboard antenna for open environments
- External antenna for improved signal in closed boxes
Robust hardware and connectivity
The board includes three power outputs (12V to 24V) and three 5V outputs, a TF card slot, and a CH340 USB serial chip support. Connectors use secure Xh2.54 pins for reliable wiring.
- Multiple output voltages for peripherals
- Onboard TF card for file storage
- High-speed USB interface for data transfer
Open-source firmware and web UI
The FYSETC E4 ships with a custom Marlin firmware fork and ESP3D web user interface. Users can configure, update firmware OTA, and control their printer easily through a familiar web browser interface without extra components.
- Custom Marlin fork for enhanced features
- ESP3D webUI accessible from PC or mobile
- Firmware updates via web interface or PlatformIO
