LILYGO® T-Deck Portable Microcontroller Programmer LoRa 915 MHz H642

T-Deck is a pocket-sized gadget with a 2.8-inch, 320 x 240 pixel IPS LCD display, a mini keyboard, and an ESP32 dual-core processor. It is not a smartphone, though it looks like one- but you can use your programming knowledge to turn it into a standalone messaging device, or use with coding software for programming.

Keyboard appearance may vary from photos: US QWERTY layout guaranteed, may have additional symbols or characters on keys in other language in addition to QWERTY but that is smaller print on the bottom of the key and would not affect operation or layout. As of 1/28/25 most all keyboards we have are white color but it is possible a black keyboard is still shipped.
