a smart tv box that is used to make non smart tv into smart tv
Description:
this a box that uses rasberry pie to power and it is connected with gpio for extra usb ports this can make your normal monitor a non smart tv into smart. rasberry run a linux that have bluestack installed and smart tv ui can be applied or it can aslo be used as a mini computer that is can perform daily task and do some coding .. i made this project for fun as i have tv its huge but not smart so i can make it smart and aslo use for coding and i can do workshop for hackclub too lol ..
Features:
40-pin GPIO header interface for Raspberry Pi Clean PCB layout with power and signal routing Stackable design using GPIO stacking header Custom 2-part enclosure (top + bottom) Cutouts for: USB ports HDMI Power input
The PCB was designed using KiCad & CAD was designed using Fusion 360:
Schematic creation Footprint assignment PCB layout and routing all the file are included in PCB and Shemantic and also cad step file
Software
No custom firmware is required.
The system runs on Raspberry Pi OS, which handles all processing and functionality. you can easily run rasberry pi os by installing offical iso iamge into the sanddisk that i have provided link of in BOM and insert in pi and you can watch any open source video on youtube for furthure code instruction
How to assembel:
To assemble the project, first solder a 40-pin stacking header onto your PCB with the long pins facing upward, then insert a microSD card into the Raspberry Pi 4 Model B and mount the Pi securely inside the bottom part of your 3D-printed case using M2.5 screws and standoffs; next, carefully align the GPIO header on your PCB with the Raspberry Pi’s GPIO pins and press it down gently so it sits firmly and evenly, ensuring correct pin alignment, after which you can place the top cover of the enclosure and secure it, and finally connect external cables such as power (USB-C), micro HDMI, and any peripherals directly to the Raspberry Pi’s ports to power on and use the system.

Questions
How big is the Smart box PCB?
It measures 77 × 105 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smart box use?
5 parts. 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 Smart box KiCad files?
From the slothfs/Smart-tv-box repository on GitHub, at the commit this page was made from: the board is PCB & SHEMANTIC/smart-box.kicad_pcb and its schematic PCB & SHEMANTIC/smart-box.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smart box design in my own project?
Its repository states no licence, so its author keeps all rights: ask slothfs before reusing the design.
