This portfolio showcases my previous work in PCB design and fabrication. It includes pictures of various PCBs that I have designed and fabricated using PCB Designing tools.
This portfolio includes pictures of the following PCBs that I have designed and fabricated:
- Home Automation PCB
- Motor driver circuit
- UWB Based Circuit Board
- ATtiny Ultra Low powered 7-segment LED clock
- Automotive grade CANBUS ckt
- And more! (Honestly, at this point I lost count and my drive is a jungle of half-documented PCBs—sometimes I’m just as surprised as you’ll be! I might need a time machine to recall why I ever built them!)
- Highspeed PCB Design Commming Sooonnnnnn!!!!!!!
Read my article where I've used Clever design practices and how I optimize the Power Density Across the Board:

Currently tackling this issues for this project and solving:
Sensor Replacement: Modify the schematic and PCB layout to remove the existing accelerometer and integrate the Diodes AH1912 Hall-effect sensor.
Motor Control Circuit Integration: Ensure the hardware connections between the STM32L011 microcontroller and the DVR8838 motor driver are correctly implemented.
Battery Management Circuit Verification: Verify the existing circuitry for the MAX17048 battery monitor.
Low power design optimization: Analyze the schematic for potential physical current leakage paths to ensure the hardware design can achieve ultra-low power targets.

Due to time limitation I haven't added each PCB's features and specifications, but as I am growing, expaninding and doing my best, I'm freelancing on Fiverr. Check Fiverr Portfolio here: https://www.fiverr.com/users/ryker007/portfolio
