Eh, I'll stick with the PocketBeagle board. It is half the price, very easy to source, doesn't require any special connectors and has those extremely useful PRUs.
Slightly larger, slower and no wireless connectivity but that is a worthwhile tradeoff.
- bradstewart 9y agoAre you actually using the PRUs? They sound fantastic on paper, but I can't shake the feeling they'd be extremely difficult to actually use.
- mkj 9y agoIn my experience the PRU code is fairly straightforward and fun to write, but wrangling Linux drivers/remoteproc/TI SDKs/devicetree etc is a bit of a hassle. https://github.com/mkj/pru-mic/blob/master/pru/asmpr0.asm https://github.com/mkj/pru-mic/blob/master/pru/asmpr0.asm is the guts of some code to read from MEMS microphones, for example.
- thom_nic 9y agoPocketBeagle unfortunately isn't sufficient for integration into a commercial product. It doesn't breakout most of the AM3357's pins. If all you need is USB/I2C/SPI/GPIOs you're OK but PocketBeagle omits things like ethernet, LCD, CAN. If I'm not mistaken PB also has no onboard wireless.
