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

Firmware: Preflashed with Meshtastic

Pickup available at 2251 NW 41st Street

Usually ready in 1 hour

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: US QWERTY layout, 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.

If the board has had altered firmware or became bricked due to a non-standard firmware flash, the board may not be eligible for return.

Bulk/High Value Order Returns

Due to the labor required to package and ship bulk orders, as well as cost and stock issues involved in replenishing items, bulk orders of 5 pieces or more are not returnable unless the equipment is defective or mis-advertised, or a return period is prenegotiated. For non-defective returns over $500, a restocking fee may be deducted from the refund to cover bank or card processing fees.


Items on backorder or preorder will ship as estimated on the item page. You can cancel an order any time up until shipment. Orders with expedited shipping will arrive in the advertised time after the order ships, not after the order is placed.

Pretty cool

I like it does what I want it to do for metastatic. I will say I feel it's more well built with the plastic skeleton around the board and antenna placement is great

All around good experience

Good ship time, good product. Thanks.

Neil Oler
Awesome and easy!

It was super easy to get a meshtastic node up and running with a keyboard, finally! I’d recommend this as a first node to anyone looking to get started.

James Powell
Awesome Device!

What can I say, a standalone Meshtastic device with a touch screen, speaker, and it's own keyboard. Plenty of cases to print from Thingiverse or printables to suit anyone's needs. Adding a gps module was super easy as well. All in all I can't think of one thing negative to say about this device I'm super happy with it.


Amazing product !
