Description

The BigTreeTech BigTreeTech ESP-07S Module is a purpose-built wireless communication solution engineered for the 3D printing ecosystem. It leverages a robust ESP8266-based core, offering dual clock speeds of 80 MHz and 160 MHz, to handle network tasks and peripheral communication efficiently. The module connects directly to the designated headers on compatible BigTreeTech mainboards, eliminating the need for complex wiring.

Its primary function is to bridge the 3D printer’s control board to a local network, allowing for remote monitoring, file transfer, and real-time control via a web browser. The module supports standard UART communication at configurable baud rates from 300 to 4,608,000 bps, defaulting to 115200 bps for reliable data exchange with the host microcontroller. With a compact form factor and a 3.0V to 3.6V power supply requirement drawing over 500mA, it’s designed for embedded operation within printer enclosures.

Key Features

Direct drop-in replacement module for BigTreeTech SKR series control boards.
Enables wireless 3D printer control and monitoring through a web interface.
Dual firmware support: ESP3D for Marlin and Duet Web Control (DWC) for RepRap Firmware.
Integrated 32Mbit SPI flash for firmware and web file storage.
Comprehensive I/O set with 9 GPIOs, UART, ADC, and PWM for expanded functionality.
Secure 2.4GHz Wi-Fi connectivity with enterprise-grade WPA2-PSK encryption.
Compact and lightweight design for easy integration into existing printer assemblies.

Applications

Wireless control and monitoring for FDM 3D printers using SKR Octopus or SKR 2 control boards.
Remote file upload and print job management via network-connected interfaces like ESP3D or DWC.
Integration into custom CNC or robotic control systems requiring networked serial communication.

Frequently Asked Questions

How do I connect and configure the BigTreeTech ESP-07S module with my SKR board?

Physically plug the module into the dedicated ESP-07S header on your SKR Octopus or SKR 2 board. For Marlin firmware, configure and upload ESP3D web interface firmware to the module via serial. For RepRap Firmware (RRF), ensure the correct baud rate is set in your config file to communicate with the module for Duet Web Control (DWC) access. The default UART baud rate is 115200 bps.

What firmware should I use on the ESP-07S, and how do I flash it?

The module typically comes pre-flashed. If you need to update it, use ESP3D firmware for Marlin or the appropriate Duet Web Control-compatible firmware for RRF. You can flash it using a USB-to-serial adapter connected to its TX/RX pins and GPIO0 for programming mode, utilizing tools like esptool.py or the Arduino IDE with the correct ESP8266 board package installed.

What is the power requirement, and how is the module powered?

The BigTreeTech ESP-07S requires a 3.0V to 3.6V power supply and can draw over 500mA during operation. It receives power directly from the host SKR control board via the dedicated connector, which supplies 3.3V. Ensure your board's 3.3V regulator can handle this additional load alongside other components to avoid instability or voltage drops.
