## Description

The BigTreeTech Panda Knomi is a miniature 1.28-inch round LCD display designed to add a fun, customizable visual indicator to Bambu Lab A1, X1, and P1 series 3D printers. It is powered by an Espressif ESP32 dual-core LX6 microcontroller running at up to 240MHz with 16MB Flash and 4MB PSRAM (plus 4MB Himem PSRAM). The 240x240 pixel GC9A01 display supports 178° viewing angle and 400 cd/m² backlight brightness.

Connectivity is 2.4GHz WiFi (802.11 b/g/n) only — Bluetooth is not supported. The Panda Knomi connects to the Bambu Lab printer's local network API to display real-time print status data. Users can upload custom GIF animations to personalize the display, with firmware supporting OTA updates via the web interface at the device's local IP. The device measures 34.6 x 37.9 x 3.5mm and draws only 0.65W rated power (5V-24V input range).

Multiple mounting options are available for all Bambu Lab printer models, including versions that do not add weight to the moving toolhead. Firmware source, printable mounts, and GIF theme packs are maintained in the open-source GitHub repository. GIF optimization via ezgif.com is recommended to maximize the number of animations that can be stored.
