README
README.mdCamera
This camera consist of a custom PCB and buttons as well as a 2.4 inch tft display with sd card slot, that can capture picture. I made this project to improve my knowledge about PCB design and also I personally really wanna make a retro camera with noisy resolution. Through this project, I learnt about high speed signals, parallel signals and heat management.
Features:
- auto-focus
- power with battery
- capture photos
- view photos
CAD Model:
Made in Fusion360.Liz Access files in CAD folder.
Assembly
Steps:
- Insert 4 heatset onto the 4 mounting holes in the bottom case.
- Insert the PCB into the bottom case.
- Using hot glue, stick the buttons onto the tactile switches.
- Align the holes of PCB onto the holes of the bottom case.
- Cover the top case over the bottom case.
- Screw them tight together.
- Charge the battery and use!!

Questions
How big is the Devboard PCB?
It measures 43.4 × 41.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Devboard use?
81 parts, built around the W25Q128JVSIQ, TLV75515PDRV, TLV75518PDRV and USBLC6-2SC6. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Devboard KiCad files?
From the LizOnAir/Camera repository on GitHub, at the commit this page was made from: the board is PCB/PCB board/Devboard.kicad_pcb and its schematic PCB/Schematic/Button.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask LizOnAir before reusing the design.
