Lilygo T-Deck Plus is a $70 handheld with GPS, LoRa, and a BlackBerry keyboard

The LILYGO T-Deck Plus is a new handheld device priced at $70, designed for developers rather than general consumers. It features a compact design reminiscent of a BlackBerry but does not function as a phone and lacks support for cellular networks like 4G or 5G. The device is powered by an ESP32 microprocessor and includes a 2.8-inch display, GPS module, LoRa radio for long-range communication, WiFi, and Bluetooth connectivity. It also comes with a built-in 2,000 mAh battery, which is an upgrade from its predecessor, the original T-Deck, which required users to provide their own battery. Both models share similar specifications, including an IPS LCD display with a resolution of 320 x 240 pixels, 8MB of PSRAM, and 16MB of flash storage, along with a microSD card reader, microphone, and speaker. The T-Deck Plus supports programming through Arduino, Micropython, and PlatformIO-IDE, with additional documentation available on GitHub. This device is aimed at hobbyists and developers looking for a versatile platform for various projects.

For some context, Lilygo dev boards are a popular option for running Meshtastic software which provides a common protocol for sending text messages over LoRA https://meshtastic.org/docs/introduction/ including a mesh relay where other radios relay your messages to a final destination https://meshtastic.org/docs/overview/mesh-algo/

(LoRA - long range, low power radio in unlicenced bands - up to 200-254km line of sight even without mesh relay https://meshtastic.org/docs/overview/range-tests/#current-gr...)

Lilygo's original lora devboards had no display and no GPS (although IO pins to add your own) and you used the bluetooth connection to a phone to send and recieve the messages.

There is a new 5G non cellular standard namely DECT NR+ that is more open, reliable and has higher bandwidth than LoRa [1]. A communication device similar to this Lilygo T-Deck running the new DECT NR+ that's backward compatible with the old DECT standard will be very exciting for off-grid and off-network adhoc wireless communication.

I dont have much interest in LoRa, I do think an esp32 device like this but with a modem would be very cool for a simple hackable phone, sort of in the same vein as the tangara mp3 player.

Are new parts being made, or are they only sourcing from old stock?

It'd be more exciting if GPS supports RTK, but still I would buy this in a heartbeat.

I use old cheap cellphones and connect stuff using an OTG serial port

Ha, I expected to read about something designed for on-device/off-network intended LLM inference of customized models (LoRA vs LoRa).
