Sayanee Basu's Video Walks Through the Design Considerations in Moving From an Arduino to a PCB
Having built a prototype on a breadboard, Basu's video will explain the whys and hows of transferring the design to a custom PCB.
Sayanee Basu has published a video guide on how to take a project from a prototype built on an Arduino-compatible development board on a breadboard to a finished, standalone printed circuit board.
"There are some design considerations to take note," Basu explains in the introduction to the video. "For example the power management circuit, or how to upload the bootloader and the firmware, LEDs, buttons, or switches, and integrate the various sensor circuits."
"Sometimes a breadboard might just be enough. Now a breadboard can be useful for many different purposes, they can be useful for education, art projects, or even deploying and testing one unit for a few days, so sometimes we might not even need to create a custom PCB. However, at other times we might need multiple units, or the components that we use can only be found in SMD packages or non-standard footprints that you have to use a custom PCB. In these cases a custom PCB can be very, very handy — along with the usefulness of it being much smaller and robust than a breadboard equivalent."
Basu's video walks through various design considerations in making the move from an Arduino on a breadboard to a standalone PCB, including switching the microcontroller, dealing with the various subsystems typically included on the development board itself, handling a switch of power supply to battery packs, dealing with the installation of a specific bootloader and firmware, and integrating the required sensors.
