- Wed Jun 24, 2015 3:52 pm #21550 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 am looking, but have not found a great source for small qty.
Let me know what you find.

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.
