Every T-Echo we ship leaves with two upgrades already in the box: our 3D-printed clip guard and antenna gap filler — free, not as an add-on. The stock T-Echo is the best pocket-sized Meshtastic node you can buy, but the bare pocket clip and the antenna connector gap are its rough edges. These two parts clean both up, and nobody else includes them.
What it does: the T-Echo is a pocket LoRa communicator that runs Meshtastic — text messaging and GPS position sharing with no cell network, no subscription, and no infrastructure. The 1.54" e-paper display sips power and stays readable in direct sunlight, which is exactly what you want on a device that lives in a pack, on a belt, or on a dashboard.
The radio side is serious: Nordic nRF52840 processor with Bluetooth 5 for the phone-app link, a Semtech SX1262 LoRa transceiver (+22 dBm transmit, −139 dBm receive sensitivity) on the 868/915 MHz ISM bands, and a multi-constellation GNSS receiver (GPS, BeiDou, GLONASS, QZSS) with AGNSS for a fast first fix. The 32 MHz TCXO keeps the radio on frequency across temperature swings.
Getting started: flash it with the Meshtastic flasher at flasher.meshtastic.org, pair it with the web client or phone app, and you're on the mesh. Questions? Email orders@yetiwurks.com — real humans in Minnesota, and we run this same hardware ourselves.
Warranty: defective boards are replaced or refunded within 30 days of purchase. Non-defective boards can be returned in like-new condition within the same 30 days.
