Tanmatsu is the dream terminal device for hackers, makers, and tech enthusiasts. Built around the powerful ESP32‑P4, and the ESP32-C6, it gives you an easy way to make, hack, and tinker wherever you are.

This Tanmatsu is shipped directly from Arch Labs in the United States, so there are no import fees, customs headaches, or ridiculous international shipping costs. All proceeds go straight to supporting Arch Labs and future projects this is not a dropship listing or some middleman stocking arrangement. Huge shoutout to nicolai electronicsfor creating such an awesome device.

Tanmatsu lets you program on the go and communicate over long distances using LoRa, while also giving you advanced connectivity and expandability for hardware hacking and development.

This version of Tanmatsu includes a LoRa module capable of tuning to frequencies in the 803–930 MHz range. An antenna is included; and the 915 MHz antenna is suitable for US regions. Check the Meshtastic LoRa region‑by‑country info if you’re not sure which one you need.
