Whow - this boards exceeded my expectations by far! - Easy to install and program with Arduino and the original libraries from Lilygo Homepage (use GxGDEH0213B72.h driver) - SD card interface - which I didnt expect on this board - LiPo management chip, just connect a 1s lipo and charge it - ePaper is pretty fast and has good contrast Thats exactly what I looked for to display my solar and smarthomes power status with a simple "out-of-the-box" board. Board is the perfect present also for every DIY Arduino freak... So I immediately ordered 2 more...
This is the third T5 I've bought and I'll probably buy more. It is unbelievable how versatile this gadget is. I even popped a fuse on one of them because I'm a bad engineer and it was very easy to bridge it with a blob of solder. The board worked perfectly after.
Perfect little board! Over the past few months I've tested every pin and feature and it all works. The partial refresh is nice, but if you use it more than a dozen times in a row without a full refresh, it can burn in a ghost image on the screen.
Display work perfect. I bought the module because I program PDA computers with reading barcodes and so I can generate those codes directly (via web) on the display, I do not have to print on paper. The sample programs work. Only refresh the display is 5-8sec.

Fast Controller, sharp display, Lipo Battery Support included. All on 1 compact Board and with really good manufacturing quality. Arduino GUI can be used for programming - my recommendation!
Delivery took longer from UK than from China, but the quality is very good, module works as described. Contrast and display are very good. Gladly again!
It's working. Overall quality is good. The received module differs from the photo, there is no LED's near the e-ink display. Typical power usage for this module is about 45-50 mA. When using WiFi (connect, send data frame, disconnect ) there is a current burst up to 150mA. In deep sleep, consumes 7.4mA.
display is working programming with the linked libraries is working
The package came very well protected and arrived before the deadline. The screen brought the last image of the preloaded program and when I connected the ESP32 device to the USB port, it executed the factory preloaded program correctly. Following the instructions of the software provided by the Banggood page, I reprogrammed the ESP32 with my own information without any difficulty. Very good purchase at a very good price!!!
