How to choose a pocket ESP32 gadget: Cardputer vs T-Deck vs T-Embed

The Cardputer is the best low-cost choice for typing and experimenting with self-contained ESP32 apps; the T-Deck is the stronger communicator because it combines a larger touch display, keyboard, trackball and optional LoRa; the T-Embed is the compact control-panel choice built around a rotary encoder. Choose the input method and radio you need before comparing firmware ecosystems, because those differences matter more than headline processor specifications.
