Arduino Giga R1 WiFi [ABX00063] – High-Performance Microcontroller with Dual-Core ARM Cortex-M7 & M4, Wi-Fi, Bluetooth, and Advanced I/O for IoT & Edge Computing

Favourite board from Arduino. Greta functionally with M& and M4 processors. I use identical SPI displays on the different processors which gives flawless results even though they have the same address. Even using 2 separate SPIs on the main processor caused issues but this technique solved it.They're not cheap - but often you can save a fair bit in a sale.I find they are more compatible (once you get used to them) than other boards and they are easy to use - communicating between the processors is slow though and M4 can't use Serial, which is a pain.I've bought 8 of these for various projects so they've got to be good for that sort of outlay. I've purchased their displays too - great quality and cameras but these are limited as to what they can do.So, not at all cheap - I've bricked 2 of them so be careful - but tremendous power and project opportunities.

Converting from Arduino Mega 2560 so was concerned at some of the dialog on Arduino forums about this board, and it there are a few teething issues as with all new boards but I have now had two applications running using the in-built WIFI and it's proving very reliable.
