Bus Interfaces
The BigTreeTech BTT RRF WiFi V1.0 is a WiFi expansion module designed for use with RepRapFirmware-compatible 3D printer mainboards. Built around the ESP8266 ESP-07S module with an external antenna, it provides reliable 2.4GHz 802.11 b/g/n wireless connectivity to boards like the SKR V1.3 and SKR V1.4 Turbo running either RepRapFirmware or Marlin.
When paired with RepRapFirmware, the module exposes the Duet Web Control (DWC) web interface for remote printer management — including file uploading, print monitoring, temperature graphs, and G-code console access — without requiring a separate SBC like a Raspberry Pi.
The module plugs into the dedicated WiFi expansion header on compatible BTT boards and comes with an external antenna for improved wireless range in environments with interference. Hardware schematics and firmware source are available in the BTT-Expansion-module GitHub repository.
