Add Battery to Cyd Yellow Board

@MuhammadUzair16

Hi I am an embedded systems engineer with over 12 years of experience in portable consumer electronics, Li-ion power design, soldering/rework, and enclosure integration. I can help modify your CYD Yellow 2.8-inch board so it runs from a rechargeable lithium-ion battery while still accepting power from micro USB and USB-C, with charging through the existing micro USB input as requested. My approach would be to confirm the board current draw, choose a suitable protected cell with charging and 5V boost/power handling, wire the USB inputs safely, and design/print a compact enclosure that leaves the screen and ports usable. I can also check heat, charging behavior, polarity/protection, and basic runtime so the result is practical rather than just wired together. Similar battery/enclosure projects cannot be shared publicly, but I can show relevant examples privately if needed. Please contact me to discuss the board version, battery size preference, and whether you want USB-C charging added or only USB-C as a 5V input.

Hello and thank you for posting this project, I'm excited to learn about integrating a lithium-ion battery into your Cyd Yellow board with a 2.8-inch screen. The requirement to utilize both micro USB and USB-C power inputs while ensuring the battery is rechargeable through the existing micro USB input is a fascinating challenge. To tackle this, I would design a custom 3D enclosure and develop a PCB layout that accommodates the lithium-ion battery and power management circuitry, allowing for seamless switching between the two power sources. Can you tell me more about the specific type of lithium-ion battery you envision using for this project? https://www.freelancer.com/u/salahuddin1973 Best regards, Naufal Salahuddin

I can do this. Custom 3D-printed enclosure for your Cyd Yellow board with integrated rechargeable lithium-ion battery, dual power input, and clean cable management. Power design: 3.7V Li-ion cell with boost converter to stable 5V for the board. Battery charges through the existing micro USB input via a small TP4056 charging module. USB-C port wired for power input as well—both can feed the board, battery charges when micro USB is connected. Power switch included for full shutdown. Enclosure: measured to fit your Cyd Yellow board with 2.8" screen, battery compartment, charging module mounted internally. Accessible ports for micro USB, USB-C, and screen. Ventilation considered. Printed in durable material, snap-fit or screw assembly. I'm new on Freelancer, not new to this. Built and assembled custom electronics enclosures for fintech and automation projects where compact, reliable power integration is critical. Deliverables: STL files ready to print, wiring diagram, component list, assembly instructions. Can also print and ship if needed. Let's talk. Share board dimensions and preferred battery capacity. — Michel
