I'm using in my current projects PD boards from Ebay, so I could be interested. Ebay boards are programmable using a single button on the board itself and are less expensive. This one is very cool but IMHO has two weak points:
1. "The board has a sensor which reads your desired configuration from the light pulses generated on this page and stores them on the onboard NVM". What if the company go out of market ? How can a customer reprogram his boards without website?
2. Is that secure ? What if a malicious actor reverse the website logic going around reprogramming the boards to provide max voltage ? It should have a safe button but, at that point, could be convenient to use directly that button to change configuration.
- oxplot 6y agoI'm very interested to know what board you're using at the moment. I did consider using a button, however given the small size I wanted the board to be, it was not possible to have anything mechanical on it. 1. The protocol is actually fairly simple and open. Everything including the website is open source. In fact the site is a single page HTML which can be saved and opened offline. 2. The point about sabotaging which others have mentioned, is a valid point and I have thought about using a sort of a password to restrict who can configure it. I haven't found a user-friendly solution to this yet. As this board is meant to be embedded inside of an enclosure, I am relying on physical obstruction of the sensor as a form of security.
