The Pi3+ has considerable faster CPU performance vs. the BBB. Also twice the RAM and good built-in WiFi. Yes the Pi's Ethernet has limited bandwidth but how much is required? In the old days people were using parallel ports on PCs and they have VERY limited data rate compared to the Pi's Ethernet.t The Pi's ethernet is not a problem in our case as not much data is being sent.
But I keep wondering why not use an Intel i5 or i3? You can buy a refurb PC that came off lease foruder $200 and it will have a power supply and case and a disk and run circles around the Pi. And if you want good graphics the PC has a PCIe slot what you can drop in an Nvidia GPU. One very promising chip in the stm32mp157. It has an ARM Cortex M4, a very powerfull real-time chip and also a dual-core ARM cortex A that can run a real-time Linux. It's new so the only products are evaluation kits form ST. This could make for a stand-alone CNC controller. https://www.st.com/en/microcontrollers-microprocessors/stm32mp157c.html On Sun, Jun 16, 2019 at 12:31 PM John Dammeyer <jo...@autoartisans.com> wrote: > > As far as I can see the only reason to consider a Pi, especially with the lower number of I/O available is because it's got better video compared to a Beagle.
