WisMesh Tag Mesh Radio

The WisMesh Tag is a credit-card-sized Meshtastic®/MeshCore® node from RAK Wireless and MOKOSMART, built for people who want a pocketable mesh radio that ships sealed, pre-flashed, and ready to ride along on a backpack or in a jacket pocket without any DIY work. Pair to your cell phone with the free app to send text messages and GPS tracking off-grid. No cell service, internet or subscriptions required.

Who it's for

• Everyday carry users who want a discreet, weatherproof mesh node that doesn't look like a radio.
• Tracking A slim node to hand out for team/asset tracking at an event or park. (No phone necessary for tracking-only)
• Great first mesh node A fully functional Meshtastic/MeshCore radio that pairs to your cell phone via Bluetooth and enables off-grid texting and GPS tracking in a compact formfactor.

Key Benefits

• 📡 SX1262 Radio with Nordic nRF52840 MCU. Uses the same radio as many other mesh nodes, and the power efficient MCU, giving you excellent battery life.
• 🔋 1000mAh Battery. Best in class battery size. Users report 5 to 6 days of runtime with GPS off and 2 to 3 days with GPS active, depending on mesh traffic and position interval.
• 🛡️ IP66 Sealed Enclosure. Rubberized housing rated against dust ingress and powerful water jets. Built for all weather.
• 📍 Multi-Constellation GPS. The AT6558R GNSS module receives GPS, GLONASS, BeiDou, and Galileo on the L1 band for reliable position locks in open sky.
• 🔘 Dedicated Reset and DFU Button. A separate button on the back handles firmware flashing, so there's no charger-disconnect dance to enter bootloader mode when it's time to update.

How it Works

Charge the Tag with the included magnetic USB cable, hold the front button to power it on, and pair it to the free Meshtastic or MeshCore app on your phone over Bluetooth. The Tag is pre-flashed with your choice of firmware before it goes out the door, so you're communicating on the mesh out of the box.

From there, the Tag rides in your pocket or clipped to a strap. It transmits your position on the interval you choose, relays messages between other nodes in range, and lights up the blue LED and buzzer when a new message arrives. View and send messages from the app on your phone when the device is paired over Bluetooth or USB.

Press the front button to send a quick position ping or mute notifications. If you want to swap firmware (Meshtastic and MeshCore are fully supported), double press the back button to drop into DFU mode and reflash from the web flasher.

Key Features

• Pre-Flashed Ships with Meshtastic from the factory, or optionally have Atlavox flash the latest firmware directly prior to shipping, and we'll configure your node and set up a private encrypted channel for you.
• Two-Button Design. Front button handles user actions (power, notifications, position ping, GPS toggle). Back button is dedicated to reset and DFU mode, which makes it easy to flash firmware.
• Three Status LEDs. Red for charging, green for power and MCU activity, blue for incoming messages. No more decoding a single multi-purpose blinker.
• Built-In Buzzer. Audible notification for incoming messages and power state changes.
• Acceleration Sensor. ST LIS2DH 3-axis accelerometer for motion-based wake and future firmware features.
• Magnetic Charging Cable. 4-pin pogo connector keeps the enclosure fully sealed. The cable doubles as a USB interface for serial logging and firmware updates.
• Internal Antennas. LoRa, BLE, and GNSS antennas live inside the sealed enclosure. Nothing to snap off and no additional antenna purchases.
• FCC and CE Certified. RAK has FCC certification (DTS and DXX) and CE certification on file for the Tag.
• Lanyard Loop. Built into the top of the enclosure. Lanyard is included in the box.

FAQ

How is the WisMesh Tag different from the SenseCAP T1000-E?

Both are card-sized, sealed, pre-flashed Meshtastic nodes around the same price. The Tag has a larger 1000mAh battery (vs 700mAh), an IP66 rating (vs IP65), and uses the SX1262 LoRa transceiver, which is broadly compatible with both current and older Meshtastic hardware. The T1000-E is slightly thinner, has a temperature sensor, and uses a dual-band GPS chip that can pull more satellites in dense urban environments. Pick the Tag for battery life and mesh compatibility, the T1000-E for telemetry and urban GPS performance.

Can I run MeshCore on the WisMesh Tag?

Yes. The Tag is based on the well-supported nRF52840 plus SX1262 combination that MeshCore supports, and multiple users have confirmed it working. Reflash via the MeshCore web flasher after triggering DFU mode with the rear button, or we can flash it for you.

How long does the battery actually last?

Real-world reports vary with your settings and mesh traffic. With GPS off, users typically see 5 to 6 days of runtime as a passive node. With GPS on at a 5-minute position interval and a busy mesh, expect 2 to 3 days between charges. Slower GPS intervals push that closer to a full week.

Does it have a screen?

No. The Tag is designed as a sealed, low-power node controlled through the Meshtastic or MeshCore phone app over Bluetooth (or USB). The three status LEDs and buzzer handle on-device feedback.

Can I replace the battery?

No. The enclosure is sealed for the IP66 rating and cannot be opened without damaging the device. Lithium batteries do degrade over time, but the 1000mAh cell paired with the nRF52840's low-power profile should give you years of useful service before you notice a meaningful drop in runtime.
