LILYGO T-Embed ESP32-S3 IOT Embedded Panel for Programmable Development Board with 1.9-inch IPS Color TFT LCD TTGO Wireless Module

Yes, these are amazing. They can do a lot of things.

The T-embed board is pretty neat, and it packs a lot power and peripherals into a small package. The LCD display is crisp and bright. The rotary encoder works, but the dial is fairly shallow so the feel is just OK. You get on-board microphones, header pins, plug-in speaker and battery connector in the handy plastic packing box. I haven’t used the header pins yet and it looks like it would be a pain to install them because you’d have to remove the front panel to get to the solder pads. The board has built-in circuitry for managing charging of a user-supplied LiPO battery. I haven’t tried the Bluetooth yet, but the on-board Wi-Fi has decent strength and sensitivity, and is easy to use. You get expected analog and digital I/O pins.I used some of Volos Projects’ GitHub example code to get started working in the Arduino IDE. Lilygo has a GitHub page with Arduino LVGL libraries and IDE processor plug-in modules for the T-embed. Oddly, the best choice of board is ESP32S3 Dev even though there is a choice for T-embed. I found sketches didn’t compile correctly unless I used ESP32S3 Dev as the board selection. The T-embed has the LCD connected by SPI, not parallel. If you’ve used other Lilygo boards, you need to reconfigure LVGL for SPI or you’ll get just a blank display when you run your sketches. I just keep two separate Arduino folders with LVGL configured appropriately are switch them back and forth depending on target board type. There may be a better strategy, but that was a quick solution.Over-all the T-embed is a really cool small board that pretty much gives you everything you need to learn ESP32 and to make really interesting projects without needing to add a bunch of parts. The nice front panel makes it easy to cut an opening into a project box, snap in the T-embed and have a professional looking result. This review is based on my experience having purchased the product without outside influence.

Only works when plugged in doesnt come with a back. I was highly disappointed

Buy version with shell, its basically the same price. Now I have to wait another 2 weeks lol.

I’m a repeated user of LilyGo ESP32 modules. I have quite a collection, like the original T-Display and continuing on to the T-Display-S3 (both touch-screen and not) as well as this one. LilyGo modules are always well thought out and come with sample code and at least basic documentation via Github. This unit is intriguing and I was considering using it as the front-end for an Internet radio I have been working with. The problem I have is the scroll wheel on my unit is extremely rough, it does not rotate easily and produces a grating sound. Since I waited too long before examining the unit I was past the return window but I would urge anyone considering this unit to check carefully, mine is almost unusable. The display quality is excellent and everything else appears to work correctly. Caveat emptor.
