Hello. Thanks for posting your project about 12-bit true RMS voltage to digital conversion. Please find below a summary of my proposal.
SCOPE OF THE WORK:
I have designed voltage and current meters for embedded applications. Have experience with AC electronics (Fence chargers, flyback converters, etc.)
Can work use a Microchip CPU, with isolated I2C slave port and simple, custom data format.
The board will be designed following good practices to guarantee a safe, reliable operation
DELIVERABLES:
- Circuit diagram (.PDF)
- PCB manufacturing files (Gerber, pick & place, drill list, testpoints, etc.)
- Bill of parts (.XLSX) with 3 vendor codes per part
- Prototype tested and shipped to your location.
- Source code and firmware image (.HEX)
- Documentation including electrical specs, pinout description and operation guide.
- 3D Render images of the board
PRICE:
PCB Design: $ 148
Firmware: $ 99
Prototype: $ 315
ETA:
PCB Design: 4 work days
Firmware: 2 work days
Prototype: 32 days
BACKGROUND:
11+ years of experience in hardware design, including:
- Circuit design and simulation (Altium Designer)
- PCB layout design, high-speed and multilayer boards
- Managing PCB manufacturing, assembly, prototyping and global shipping
- Programming in C, C++, Arduino, Python, Pytorch
Please check my portfolio with examples of past jobs. Hoping it will meet your requirements.
Looking forward to helping you with this project.
