Important: 868 MHz for Europe
Always buy the 868 MHz version for use in Europe. The 915 MHz version (US) is not allowed in Europe.
What is the PiComputer S3?
The PiComputer S3 is a unique Meshtastic device designed by Bobricius, a hardware designer from Slovakia. It combines an ESP32-S3 with a physical QWERTY keyboard and color screen in a compact cyberdeck format.
Unlike most LoRa devices, the PiComputer has a full 30-36 key keyboard, allowing you to type messages directly without a smartphone. The 2.8" IPS color screen offers excellent readability.
This is a niche product for enthusiasts who want to build a standalone communication device. It's also known as part of the "Armachat" project.
