Just to let you know that WeMos have launched the D1 mini pro, this has superceded the version 2 which is no longer available on aliexpress.

It has 16MB of flash and can use an external antenna.

My first shipment of them should arrive today or Monday :slight_smile:

Thanks! Sold out right now, but I’m sure they’ll be back: https://www.aliexpress.com/item/WEMOS-D1-mini-Pro-16M-bytes-external-antenna-connector-ESP8266-WIFI-Internet-of-Things-development-board/32724692514.html

And it looks like the local post office has lost my first shipment.

Happily I’d already ordered some more before WeMos ran out.

WeMos expect them to be back in stock in about a week.

Just got my shipment yesterday. Haven’t tested them out yet though. I’m actually more interested in the ESP32 boards that have started showing up. Higher clock speeds and more analog inputs as well as an extra cpu core that mostly handles the WiFi stuff.

Thanks @Brian_Lewis ​. They do look very promising, I currently use an ESP8266 as a wifi web interface and a teensy to do the hard work. These look like they might replace both :slight_smile:

@Jeremy_Spencer I’ve been considering trying that on a new project, do you just send commands from the ESP8266 to the Teensy over Serial? I’ve used the D1 mini alone to drive the LEDs and serve a web UI for control, but have noticed hiccups, hangs, etc. Especially when using the web app.

Hi @Jason_Coon ​​, yes I use serial, specifically the EasyTransfer library. It may not be the fastest or have the lowest overhead but it’s very easy to use and seems to work flawlessly on both boards…
