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.

GPSR Compliance Manager

Build quality is 3/5 3d prints don't mix well with stiff controls on t-deck complete

Device works fine, but the 3d printed power switch is not tough enough for how tight/stiff the switch it self is. You have to use a fingernail or tool to get enough friction to actually move the sliding switch to turn off and on. I broke the 3d printed part of the switch off almost immediately. If I buy another t-deck I'll probably buy one of the ones that isn't 3d printed for this reason alone. the case makes the buttons and trackball sort of recessed into the device which makes them less accessible. Buyer beware.

Lilygo T-Deck Complete

I had been considering an all-in-one LoRa device and looked at a couple. The T-Deck, seemed to be the best for my needs. After looking at the T-Deck Plus, I saw for a few dollars more, I could get the T-Deck complete that Rokland put together with an external antenna verses the Plus' internal antenna and 3000 mAH battery instead of the 2000 mAH battery the T-Deck Plus came with. The unit was set up ready to go with stable 2.5 Meshtastic firmware out of the box. After familiarizing myself with the T-Deck with the 2.5 software, I loaded the latest beta that had just come out, the 2.6 with UI and the T-Deck stepped up to another level. I take it everywhere I go now. Battery life has been 18 to 24 hours minimum. Loading the maps were easy and it's nice to have a real time map of nodes in my hand without having a cell phone. I am looking at buying another T-Deck Complete.
