Lilygo has launched yet another ESP32-S3 board with an integrated display, but the T-HMI has a larger 2.8-inch color display and a resistive touch panel suitable for HMI (Human Machine Interfaces). It is also equipped with three Grove connectors for expansion with sensors or actuators.

Like all the recent ESP32-S3 boards from Lilygo, the T-HMI features the ESP32-S3R8 WiFi 4 and Bluetooth MCU with 8MB PSRAM, as well as a 16MB SPI flash, a microSD card slot, a few buttons, and power from USB or a LiPo battery.

Lilygo T-HMI board specifications:

The T-HMI board relies on its USB as the JTAG upload port with the operating mode selectable with the BOOT button. Sketches for Arduino/PlatformIO are provided with code for factory testing, ADC, the SD card, the TFT display, the touch panel (including calibration), and an LVGL GUI benchmark. You’ll find those on GitHub along with the PDF schematics and a firmware image.

Lilygo sells the T-HMI display board on Aliexpress for $22.78 including shipping, but not taxes for our European friends. It’s a promotional price valid until April 22, and the normal price is said to be $23.98…
