yyrkoon 250 Posted September 9, 2016 Share Posted September 9, 2016 So we've been working on a project that required that beaglebone to be rock solid in a remote location. In order to do this we had to add a few things . . . 1) A working watchdog circuit. As the on die watchdog for the am335x either does not work properly, or does not function after the board loses power 2) A functional RTC. As the on die RTC does not keep time when the beaglebone loses power. 3) Additional battery functionality circuitry. As the PMIC on the beaglebone does not take several things into account. Such as disconnecting the battery when the 5v input goes missing. But this can not be done arbitrarily. It needs to be done in a clean fashion. To keep form corrupting the mmc media the board boots from. All or most of the above was a design / cost decision made by the person who designed the beaglebone. As in, 'fine you want that feature ? well it'll raise the cost of the board' type situation. So I can certainly understand where Gerald was coming from. I rather like the idea of buying a $45 BBG with what it does have ( as it sits ). Anyway, we're designing a board around the above mentioned items we added into the custom cape we designed. However, we'd like to hear from others what else would be usefull to add to such a cape that would make the cape useful for many people while keeping the cost down( affordable ) for the hobbyist. We've tossed around a few ideas such as adding x amount of grove connectors. Or simply a 'port multiplier' type 'port' for an I2C bus, where one would add x amount of I2C devices / sensors. What would *you* like to see in such a cape ? Quote Link to post Share on other sites
