ESP32 T-Display LCD Wi-Fi BLE CH9102F Chip TTGO Development Board

Great board, but a bit hard to set up. After finding a handful of special settings (make sure you turn on the backlight, change the driver, change the default pin values, etc.) it works perfectly. It runs fast as expected, and the display looks good in full RGB, but is a bit small. It gets a bit hot when charging the battery (specifically near the connector) and the rest gets hot (screen and especially the controller behind it) when using wifi. It's not too hot, probably isn't an issue, but you probably don't want to put it in a sealed box. The USB C is also great. One annoying thing I found is that you can't properly connect the header pins to the board on one side because a small component pokes out too far. That is, if the headers are on the opposite side to the display. It can't fit on a breadboard unless you put the battery connector hanging off the board, which allows just enough room to put the pins in. I like the two built in buttons. Good for misc controls. It has a micro JST connector for charging batteries, so make sure you get the right battery connector size or else you'll have to do some extra wire splicing like me. It is really hard to pull out the connector, so don't rely on it for swapping batteries. I don't know too much about microcontrollers, but this was a great value for the money for me because it had all the components I would otherwise need to buy in bulk - battery connector/charger, display, buttons.

Good product, but a lot can go wrong during implementation.

Great product! Works as intended.

I've purchased a few of the LILYGO ESP32 T-Display modules and found them to work very well. The ESP32 makes these boards powerful, and the integrated color display makes them ideal for a lot of small little projects. There's also plenty of code out there for these and many useful libraries so you won't be left out in the cold!

I recently purchased the ESP32 microcontroller and wanted to share my thoughts and experiences to assist others in making an informed decision. Overall, the microcontroller offers an array of features and an impressive display, but it does come with some notable drawbacks that potential buyers should consider. Let's start with the positives. The display on the ESP32 microcontroller is truly a standout feature. The colors are vibrant, and the visual quality is remarkable, especially considering the price point. It surpasses standalone displays I have used in the past, making it a worthwhile investment. However, I must address the setup process, which proved to be quite challenging. While the microcontroller does not come with clear and concise instructions, I discovered YouTube tutorials that were instrumental in guiding me through the setup. I highly recommend watching the tutorial titled "How to Install and Setup TTGO T-Display (Getting Started tutorial)" for a step-by-step walkthrough. One notable frustration was the incorrect information provided in the GitHub repository for setting up the ESP32 T-Display Module. This inconsistency caused confusion and wasted valuable time. It would greatly benefit future buyers if the manufacturer addresses this issue promptly. Another aspect that impacted the overall user experience is the labeling and arrangement of the GPIO pins. They are organized in a manner that is not intuitive, making it difficult to identify and connect the appropriate pins. This design choice could be improved to enhance user-friendliness and streamline the setup process. On a positive note, the microcontroller offers a range of impressive features and capabilities. Its performance is commendable, providing reliable functionality once properly set up. Additionally, the inclusion of a 3D printable case in the GitHub repository is a thoughtful touch, allowing users to protect and organize the microcontroller components effectively. In conclusion, the ESP32 microcontroller offers a compelling package with its outstanding display and diverse capabilities. However, the challenging setup process, incorrect information in the GitHub repository, and unintuitive organization of GPIO pins present significant hurdles for users. With the help of online tutorials and some patience, this microcontroller can be a valuable asset in various projects. If you are willing to invest time and effort into the setup, the ESP32 microcontroller can deliver satisfying results.

The built in screen is clear and really nice. It's cool that it's fast enough for mjpeg video or gif playback. The documentation could be a little better but it's hard to complain at this price.

The ability to dump serial to the screen during development, the j2 battery connector on the bottom, the on/off switch, USB-C connection, all at the size of a normal ESP32. I still can't believe they managed to fit the processor under the screen. Wish it weren't so pricey but you get what you're paying for. Will buy again.

It's nice to be able to output error messages to the TFT, though configuring it can be a little complicated if you want anything fancy. The software package includes a printable case, and all the board's source files, which is great for learning.

As same as the photo and works very well

Bin sehr zufrieden mit dem Display! Habe es in homeassistant integriert und es läuft ohne Probleme

This is a powerful microcontroller for Arduino development. Quite a lot of performance and features for the money. The display has good colours, and the libraries make using it pretty easy. I don't even need the wireless capability for the projects I'm messing with. BLE does bring some ideas to mind, though. The battery charging built in is a significant bonus! Well built unit, quick shipment. I only wish the display was easier to mount in a project box.

Doet wat je er van verwacht. Ik gebruik deze als Tilt Bridge en werkt perfect. Display is goed bruikbaar en het zowel de wifi als bluetooth functies werken hier goed voor.

Utiliser dans le cadre d'un detecteur de CO2, l'affichage est pleinement fonctionnel, que ce soit en mode payasage ou portrait. Et vraiment c'est quasiment du plug and play, pas besoin de beaucoup de connaissance pour le mettre en service.
