I've made a bunch of 'prototypes based on the ESP-01...

It looks like i'll need to have more flash in order to use the OTA features in the arduino IDE.

Can someone recommend (with a link if allowed) for a drop in replacement flash chip.. 4M preferably that i can solder on to an ESP-01 to 'upgrade' it... this would be much easier for me than rebuilding the prototype to be ESP-07/12...

many thanks.

I have found this List:

1 Winbond W25Q40 1340ef 512 KByte 0.32 each 7.85 (per 25)
2 GigaDevice GD25Q40 1340c8 512 KByte 0.32 each 7.85 (per 25)
3 Winbond W25Q32 1640ef 4 MByte 0.42 each 4.14 (per 10)

I am looking, but have not found a great source for small qty.
Let me know what you find.

I sucessfully upgraded both ESP-01 and ESP-07 with a W25Q80BV. Go to your favourite onlined store and search for W25Q80BV. You want the narrow one (150-mil). Chances are you'll find only the wide one (208-mil). Just bend the pins a little and you'll be able to solder it.
