What you’re building

MicroPython-based application launcher and lightweight operating environment built specifically for Cardputer. This listing preserves the original source and the exact device relationship rather than republishing the creator's work.

Key steps

  1. Open the original project source and confirm its supported hardware or board revision.
  2. Read the setup, dependency and safety notes before flashing or assembling anything.
  3. Reproduce the smallest working example on hardware you own or are authorised to test.
  4. Record the working versions before you customise the build.

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.
