I was looking at all the ESP models and it seems there is nothing that really suits my requirement.
I think the ESP-05 would be great, since it allows an external antenna, and pin headers, however, most of those only ship with 512K of flash. I was hoping to get a bit more... 4MB would be perfect. Considering my code is 650k, and I want to be able to do OTA updates, I'm stuck.
The 12E has 4MB but doesn't have the smc external antenna mount or pin headers. I can get them with nodemcu's but still don't have the antenna and now the price just went up for the cp2102 built in...
So the question is - what's the best thing to do here?
I asked a few suppliers on ALIbaba if they can do the ESP-05 with 4MB and am waiting to see what happens.
But should I just try to dig up the schematics and then get a custom PCBA done for this so that I can get the 05 with a 4MB chip
- or am I missing something blatantly obvious here.
Again the requirement is->
ESP8266 with:
-4MB flash
-smc external antenna mount
-pin headers
Thanks...
