PCB design -- 3

Job Description:

As most of the freelancer were unable to design the boards which had calculation part for the regulator ic,i have modified the regulator ic so that it would be easy to design.

So,I am looking for guys to help me in completing my schematics for the following ones:

1) ESP32 based board

2)GD32/W80X series/similar (any one of the ic based board)

3)AT32F435/similar ic based board

4) Power distribution board based on TX4131L/similar chip with input voltage of 65 or 70V dc and output of 5/12V @2A/above.

5)GPS module based on ATGM332D-5N/similar and another one based on L86 GPS module.

I have partially completed the above given circuits schematics to some extent(~85%) and need assistance in completing the whole boards especially in the calculation part and pcb [login to view URL] the boards share about 85% of components and circuit in common.

I need assistance in completing the circuit and route the board into compact shape within 4.9×3.9 cm ,2 layer (preferable) or 4 layers, double sided. Check the model reference image for board shape only.

Please note that the schematics is not Fully completed and requires impedence control for the esp32 ,GPS and calculations

Take a look at the partially completed schematics i have attached with this request for the esp32,GPS module. The time is critical only 1 week of time.

Total boards: based on the above given ones

A) [login to view URL] boards who's schematics need to be completed and pcb routed: 4 (ex: esp32 , voltage regulator board.)

B) [login to view URL] boards which requires design review and minor changes: 2 (ex: gps boards)


A) Don't apply without reading/seeing any of the content here and also don't apply if you don't know calculations.

B) only apply if you know to use ESD protection using TVs diodes, filter design and impedence matching stuffs.

C)The project is time critical so,if you can't deliver within a week then don't apply.

D) Creation of footprint and schematic module may be present in the design for some components.

E) Don't bid your quote and ask for budget extension via chat, it's unprofessional and cheap tactics.

F)Don't quite/runaway after awarding the project by saying "the bid i made for the project won't be sufficient or consume more time to design than i thought". In reality those who can't do the calculations part/ESD protection/filter design used to say that and use it as an excuse to quit/runaway. If you are one of them please never ever apply and waste my time.

G) All the files are in easyeda format and i would export them in altium format if asked.

Special conditions:

A)The Boards on s. no : 2&3 will change over time after fixing the board specs and chip. The specs and chip specifications will be noticed to the selected freelancer.

B) Advance payment will not be entertained.

C) Budget extension will not be entertained
