Flash Chip Size

WIFIO is a dual Arduino WIFI module (ESP8266+ATMEGA328P) FCC approve-able with transferable licence. Can use the 328P for I/O expansion also...

Flash Chip Size

There isn't much difference in cost between a 512KB and a 2MB chip (e.g. W25Q16BVSSIG) and it sure is nice having the extra space for SPIFFS or whatever. I'm currently using the Olimex ESP8266-DEV board that has 2MB Flash chip.

Not only between W25Q40 and W25Q16, but also with W25Q32, and I've even found some W25Q64 cheaper than W25Q32 on eBay.
So, W25Q64 (8MB) will be handy ... :)
