The BigTreeTech Panda Branch V1.0 is a USB power expansion board designed for Bambu Lab X1, P1, and A1 series 3D printers. It takes a 24V DC input and converts it to 5V to power up to four USB-A accessories simultaneously, such as LED strips, display panels, webcams, or other low-power peripherals.
The board features a compact 145 × 20mm profile with all interfaces aligned in the same direction for simplified cable routing. A DIP switch allows precise output current selection, and each USB output is individually protected with overcurrent fuses. A red fault indicator LED activates automatically during overcurrent events. The MX3.0 2×2 pin interfaces provide power connections compatible with BTT AMS and AMS Lite accessories.
Rated at 5V output at 2.7A peak with reverse polarity protection on the DC input, the Panda Branch simplifies accessory wiring for Bambu Lab printer owners. Hardware files and the user manual are available in the GitHub repository.
