Cardputer is actually a small complete computer from M5Stack. It is powered by M5SampS3 (ESP32-S3) and includes a complete alphanumeric keyboard, a color TFT display, a microphone and speaker, an IR port, a built-in battery, and a MicroSD card slot. All of this on the surface of a regular payment card (or rather a stack of cards, thickness is 17 mm).
In addition, you will receive a unit for wireless LoRa communication, which can connect multiple devices together, or wirelessly connect various sensors.
For this year we have a new online schedule planner, where we will continuously add individual SIGs.
