💬 ESP-LINK ESP8266 WeMos D1 Mini Adapter Board

[mfalkvidd]

@NeverDie I usually buy mine for $2.60 or even $2.47 so the sale is not that big. They've just yanked up the "standard" price now to make it look like the sale is on.

[scalz]

and there are lot of wemos clones! seems there are people which receive it with an inverted soldered esp8266 or with doubtful parts quality! seems crazy!

i don't have one like this, but multiple people have reported this!
well, it just needs to unsolder, but i laughed when i saw the pic :)

[korttoma]

wow, do they have trained monkeys doing the soldering or some guy soldering them the wrong way on purpose.

[NeverDie]

Or maybe they're selling them cheaply because they're rejects that were soldered wrong, and they know it.

Where do you buy them for that price? I remember Wemos selling them for $4 when they first came out, and then I stopped checking. Even $2.60 seems like a good deal to me if the seller has a high reputation.

Here you will find some cheap ones for today:

The $2.34 one is "no longer available."

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 :)

[NeverDie]

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]

[NeverDie]

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

[NeverDie]

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.
