| Or $19 for the easy module, inc flash & emmc… [0] Although since I recently discovered [1] that the R-Pi has an exposed memory interface bus (Secondary Memory Interface, SMI) on its GPIO, I’m far more inclined to use them instead. Getting low-latency/high bandwidth I/O into these “A” (rather than “M”) processors has always been the thing that made using an I.mxRT, STM MP1 or Zynq attractive to me. Turns out the lowly Pi has had that capability all along… Coupling a Pi via SMI with a low-end (read: cheap) FPGA (Ice40K, or Efinix, hell go to town and get an Efinix T20 with 195 io for $8) makes a potent device, IMHO. You can still get an rpi zero W for $15 [2], and even the quad-core zero 2W if you shop around is ~22€ [3], which blows the STM away in terms of CPU, video out, ease of development etc. [0] https://www.myirtech.com/list.asp?id=726 [1] https://www.eevblog.com/forum/projects/state-of-raspberry-pi...
