This PCB project was for a gaming product and uses an MCU device from nouvton semiconductors. I provided PCB design and component selection consultancy. the breadboard prototype was already designed by the customer. This project comes with a challenge that the PCB must fit into the enclosure of a polyhedron shape and the placement of connectors should be in a way that it uses a small possible wire length. The project initially proposed was with ATmega devices from the client, but after extensive research and understanding client requirements I suggest Nouvton Device save cost, I also worked on other factors to reduce cost, and the cost was reduced from 11 USD per unit to 6 USD per unit.

A hierarchical design is one where the structure - or sheet-to-sheet relationships - in the design is represented. This is done with sheet symbols, which represent lower sheets in the design hierarchy. The advantage of the hierarchical design is that it shows the reader the structure of the design and that the connectivity is completely predictable and easily traced since it is always from the child sheet up to the sheet symbol on the parent sheet. Another advantage of a hierarchical design is that it provides the platform for the delivery of a sophisticated design reuse system.

With great power comes great responsibility (great thermal challenges) The most challenging part while working with a heavy current system is designing a circuit that will not burn the board in the first go. Recently I worked on 65W PSU, here are a few design practices I followed to keep things cool. 1) Used heavy copper in external PCB layers, this decreases the resistance and hence increases the thermal capacity of the board. 2) Created pass-through holes in power-carrying tracks/planes this allows air to pass through tracks cooling them down. 3) Removed Solder mask above power-carrying tracks/planes allowing heat to be directly radiated into the air. Apart from design practices, techniques like Thermal Protection, Over current protection, and reversed polarity protection are used on the circuit level. Furthermore, a selection of components is done in such a way that they can handle extreme temperatures giving time to the system to shut off without failure.

This project is ESP32 and RS485 based industrial controller designed in the KiCAD tool. The project involved the selection of proper components for RS485 controller IC & Power Supply, rectifying design mistakes (any). The Critical part was the RS485 circuit as RS485 works on a 5V logic level and ESP 32 has 3.3V logic levels.

Project started out fine. Speed was of the essence but a number of design problems were discovered by me. Had to review even the smallest detail. Later on reply time was growing to sometimes several days.
