💬 ESP-LINK ESP8266 WeMos D1 Mini Adapter Board

[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.

Which one did you order ? Can you provide the link please ;)

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.

[NeverDie]

Anyhow, I think I'll order one of the 16 Megabyte "Pro" versions to give it a spin. I hear you can now run Micropython on an ESP8266, and that might be fun. Who knows? Maybe it could even function as an MQTT server. That would be cool if it could.

I have bought all my Wemos D1 (30 pcs) from the original seller to get sure they work and they do.

I would do the same, except the original seller doesn't ship by ePacket delivery. I'm guessing less expensive clones are probably fine for experimenting with, but for an install that needs to last for years and not fail I imagine Wemos (aka "the original seller") maybe has more reason to care about quality control and not cut corners since it's their branded name on the line.

I'm curious to know: what is it you're doing that requires 30 D1 Mini's?

Haha, good question and here is the answer:
We have created a IR/RF Blaster ;-)
The video and description show you not the newest version, but it give you an idea of it.

I was inspired by mysensors member "blacey" - https://forum.mysensors.org/topic/1402/ir-blaster-progress
because he never finished his project ;-)
