There's a catch on the $2.57 listing. I could only get free shipping if I purchased a single unit. If I attempted to buy more than one in a single order, then shipping was no longer free.

[mfalkvidd]

@NeverDie yes. I usually create a few orders of 2 each. Sometimes they all arrive in the same package, free of charge :)

I just now noticed that there's a new version 2 of the D1 Mini. So, maybe the version 1's are priced low because they're being liquidated? Anyhow, Wemos claims it's more stable and has 30% greater radiated emissions. So, I decided to order some of those instead.

I ordered it from:

Whereas this link explains it better:

@NeverDie if I understand correctly, the difference is in the pcb antenna. That explains why the shipment I received earlier this week look different :)

@mfalkvidd
The second link I provided didn't mention the antenna. Rather, it showed this:

I notice Wemos now also has a 16 Megabyte version of the ESP8266. i.e. 4x the flash of an ESP-12F. I suppose that would make it a better webserver.

[mfalkvidd]

@NeverDie sorry. You had not posted the second link yet when I wrote my reply.

I noticed the larger pcb antenna on your first link so I thought that was the difference, but the ones I have are the old version then, they don't have the v2 stuff on the back side.

The 16MB version sounds nice. I have had trouble fitting all javascript and images on the 4MB version.

[NeverDie]

I think the Version 2 WeMos must have been out for a while already, because the Wemos's I already have and which I purchased a while ago appear to be the Version 2 variety. So, maybe it's old news.

Well, then, here you go: https://www.aliexpress.com/store/product/WEMOS-D1-mini-Pro-16M-bytes-external-antenna-connector-ESP8266-WIFI-Internet-of-Things-development-board/1331105_32724692514.html?spm=2114.8147860.0.0.wNYDeV

Not much of a bump in price either. Just $5.

[mfalkvidd]

@NeverDie thanks.

I've been planning to either offload the files to a cdn (but that only works when the device has an Internet connection of course) or store them on a SD card (which would give access to gigabytes of storage) but there might be cases where the 16MB is a better alternative.

@mfalkvidd said:

Are your boards clones? They look different than mine. Mine have rounded corners, and they say WeMos.cc on the front. Yours don't have that.

[mfalkvidd]

@NeverDie they are probably clones yes

Back side:

[NeverDie]

@mfalkvidd

Apparently all of yours are version 1 then, irrespective of the Antenna.

[NeverDie]

I don't think WeMos ever made one with the ESP-12E antenna. IIRC, from Day 1 WeMos was using the ESP-12F. From what I've heard, the 12F antenna is significantly better than the 12E and predecessor antennas. I originally purchased ESP-13 modules, because they had the upgraded antenna, but that was before the ESP-12F came out. I'm happy with the ESP-13's, but I don't know that they have any advantage over the ESP-12F. I now prefer the ESP-12F, if only because it's a bit more compact. Also, the ESP-12F has an LED on the module, whereas the ESP-13's don't.
