XIAO ESP32s3 (Sense) Camera for Prusa XL

————Required Hardware————

Item Cost

Seeed Studio XIAO ESP32 S3 Sense ~$24

IKEA Lillhult USB-A to USB-C Cable ~$5

Old Apple (iPhone) 5W USB power adapter ~$0

5 × M3-0.5x8mm Socket Cap Screws ~$4

I pick the Seeed Studio XIAO ESP32 S3 Sense because of its small size, lower price-point, and excellent WiFi signal .

————Software Setup————

I was unable to flash the camera firmware using the provided binaries provided on the Prusa-Firmware-ESP32-Cam .

However, I carefully followed the instructions for how to compile software in the Arduino IDE and successfully got the everything working. I am now able to flash new firmware using provided binaries.

————Remixing & Assembly————

1) Case Selection

Because the Seeed Studio XIAO ESP32 S3 Sense can get very warm, I wanted a case with maximum airflow and I found Camera Case Xiao ESP32S3 Sense by brunnair .

I had to make a couple small adjustments to make the hardware fit. ( reference " Differences of the remix compared to the original " for additional details )

2) Ball and Socket Connector

Then I need a way to connect it to my PrusaXL.

I used the ball and socket connector from the ESP32-S3 EYE camera cover / mount and remixed with the Camera Case Xiao ESP32S3 Sense housing mount.

3) PrusaXL Mount

Next I then printed the ESP32-S3-EYE cam mount prusa XL . This let me attach the camera to the left side of the upper arm of the Prusa XL.

I needed a way to keep the mount attached so I printed M3 T-slot nut (M3nEs nut) and attached it using the last (5th) M3-0.5x8mm screw.

4) PrusaXL Mount

For improved cable management and visual aesthetics, I used the slots in the T-Frame to hide the USB-C power cable for the camera. I then printed two T-Slot Extrusion Channel Covers for the horizontal sections (top under & lower outer) to cover the cable and keep it hidden. NOTE: the vertical channel cover comes as part of the PrusaXL
