Teyleten Robot D1 Mini ESP32 WLAN WiFi+Bluetooth Internet of Things IoT Development Board for Arduino NodeMCU (3pcs)

This is a simple and easy to use ESP device, below is the chip identification:Chip is ESP32-D0WD-V3 (revision v3.1)Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme NoneCrystal is 40MHzIn Arduino IDE I selected Wemos D1 or ESP32 Dev Module, both worked.

Currently I am using a esp8266 for my Les projects, but plan to move to esp32. These are faster and have more functionality.If you’ve ever uses led light strips that are addressable, heck even if they aren’t, you need this software. The software is WLED Has many built in patterns, even has adjustable and can create segments out of one strip. Just go to install.wled.me. It’s completely free and has a discord community as well!With esp32 you can even have sound reactive lights! Esp32 is the way to go!

First, these boards work fine. I like the silk screen pin numbers. However, two things:If you use PlatformIO, you have to make your own board configuration. Not a big deal, but maybe a little bit of a learning curve if you've never done it before.But the main issue is that, while a smaller form factor might be a good thing if you're soldering this to a PCB, double row headers obviously cannot be used on a breadboard, so you'd have to solder headers into it then put a wire from the header to the breadboard, which is really messy. I've stopped buying the double row system because of this, and will reserve these for use in the final PCB.

All three have downloaded programs successfully with no hassle and no button pressing. The size is perfect for fitting into small enclosures. The double row of pins on each header makes customary breadboarding a real task, but that's part of the space saving feature. Overall, these are a great choice.

Used these with Home Assistant ESPresense to detect where people are in the house. Work well for being so inexpensive! Fun project!

At first, I'd thought that these were faulty because my WLED installations via the webloader were not working. I found that during the installation you've got to press the boot button a few times in order to get the install to get going.What I like about the D1 mini form factor is that it does not have pinheaders already soldered in. I tend to like to solder my wires to the pads directly and keep the projects minimal.

I bought 2 sets of these D1 Mini ESP32 WiFi Bluetooth IoT Development Board. The chip information is not mentioned in the product description or on the board; and therefore cannot find the windows 11 serial drivers necessary to connect them.

It was more useful than I thought.Low price, came fast, and is more useful in many applications.
