Is a less-complicated (and more easily verified) PCB too difficult to design? Arduino may be easy to use for proto, but not going to be simple to verify. Plus, you are now slave to their supply chain, for a need that may be much simpler than what the Arduino board offers.
- cozzyd 7y agoThe Arduino Uno MCU is fairly widely available: https://octopart.com/search?currency=USD&q=Atmega328p&specs=1&in_stock_only=1&sort=median_price_1000&sort-dir=asc&start=10 https://octopart.com/search?currency=USD&q=Atmega328p&specs=... although there are others MCU's with even better availability (e.g. the SAMD21, which also has plenty of dev boards and it seems like Microchip has extensive stock on hand, for example https://www.microchipdirect.com/product/ATSAMD21J17A-MUT?productLoaded=true https://www.microchipdirect.com/product/ATSAMD21J17A-MUT?pro... ). One can take any of the devboards a a reference design.
- fallingmeat 7y agoOf course, I read the original comment as relying on the entire Arduino Uno board, which is both expensive and restrictive to your supply chain. Individual components, such as MCUs could more easily be selected to avoid those two issues.
