PCB & Firmware Finalization for Calculator
Budget: £250 – £750 GBP
Electronics Engineer Needed – Finalize Calculator PCB & Firmware (EasyEDA)
I am looking for an experienced electronics engineer to review, finalize, and improve an existing calculator project that was previously developed but has some unresolved issues.
Project Scope & Requirements:
✅ Verify & Correct BOM (Bill of Materials)
The current freelancer could not provide the correct part numbers needed to manufacture the board via PCBWay.
Ensure all components match the design and are available for order.
✅ Review & Fix Firmware (EasyEDA)
The firmware/code was provided, but I am uncertain if it works correctly.
Need a firmware expert to review and adjust any necessary fixes.
Ensure all button functions are correctly mapped.
✅ PCB Adjustments & Optimizations
The project was converted from a dual-PCB design to a single PCB.
Ensure all traces, connections, and components are properly adjusted in EasyEDA.
The layout should be more compact to allow for a two-strip battery setup.
Increase the number of buttons from 12 for full calculator functionality.
✅ Coordinate with Case Designer
I have hired a 3D designer to create the calculator shell, but they will need precise PCB dimensions.
You must work alongside the designer to ensure the enclosure fits properly.
✅ Project Files & Access
I have all the existing files and will provide access to the EasyEDA project.
I can add you to a chat with the previous freelancer so you can review what has been done so far.
Ideal Candidate:
✔️ Experience with EasyEDA & PCB Design
✔️ Strong knowledge of firmware development & debugging
✔️ Familiarity with component sourcing & BOM verification
✔️ Ability to collaborate with a 3D designer for final casing design
✔️ Fast turnaround & ability to work efficiently
If you are confident in taking over the project, fixing the errors, and finalizing it for manufacturing, please apply!
