Seeed Wio Tracker L2 Pro First Look: Touchscreen Meshtastic

Seeed’s Wio Tracker L1 Pro has been one of our favorite pocket nodes for months, so the Wio Tracker L2 Pro got our attention. It isn’t a refresh of the L1. Seeed moved from the L1’s low-power nRF52840 to an ESP32-S3, and built a standalone messenger around it: a 3.2-inch color touchscreen running Meshtastic’s full touch interface, a speaker and microphone, Wi-Fi, microSD for offline maps, GPS and a 3000 mAh battery. Seeed lists it at $59.42.

It’s the kind of device the L1 Pro isn’t: something you can message, check the map on and type on without a phone. The trade is power. An ESP32-S3 with a big lit screen draws far more than an nRF52840 with a small OLED.

We’ve had a pre-release alpha test unit, and it’s the board we built our MeshCore port on (more on that below). Retail units can differ from early hardware, so the specs here come from Seeed’s product page and wiki, and the Meshtastic and MeshCore source. Our alpha unit looks a little different from the release model, and Seeed asked us not to show it, so the photos here are Seeed’s. Seeed links in this post are NodakMesh affiliate links, and the price is the same either way.

What’s Inside

The core is Seeed’s Wio-S3 module, a dual-core ESP32-S3 with 16 MB of flash and 8 MB of PSRAM. That memory is what lets it run a touch UI and offline maps, and it gives Meshtastic room to remember far more nodes: on an ESP32-S3 with that much flash, 2.8 keeps full records for 250 nodes, plus a lightweight list of up to 2,000 more.

The LoRa radio is the familiar Semtech SX1262, with a 3.0 V TCXO. Seeed rates it at 20 dBm on US915 and 14 dBm on EU868, and claims range “up to 5.8 km.” Note that’s a little below the 22 dBm of the L1 Pro.

GNSS is a Quectel L76K (GPS, BeiDou, GLONASS and QZSS), the same receiver the L1 Pro uses.

The screen is a 3.2-inch IPS capacitive touchscreen at 320 × 240. There’s no physical keyboard; Meshtastic gives you an on-screen one, and a later firmware change adds support for an external keyboard on the Grove port.

Audio comes from an ES8311 codec, a microphone and a small 0.8 W speaker.

Offline Maps

This is the feature that sets it apart. With map tiles on a microSD card, the L2 Pro can show other nodes’ positions on a real map, with no phone and no signal.

Power and Charging

The 3000 mAh battery charges over USB-C (5 V, 1 A) or from a solar panel through a JST-PH input that takes 5 to 13 V. Seeed rates charging from 0 to 45 °C and operation from −10 to 55 °C. That lower limit matters if you’re in a cold climate like ours.

Seeed doesn’t publish battery life, and a pre-release unit isn’t a fair test of a retail one, so we won’t put a number on it yet. An ESP32-S3 driving a 3.2-inch screen is a different power class from the nRF52840 trackers. Expect to charge it like a phone, not like an L1.

Full Specs

L2 Pro vs L1 Pro

They’re for different jobs. The L1 Pro is a pocket node: small, efficient, and paired with your phone. We got about five days of moderate use from ours in our L1 Pro review. The L2 Pro is a standalone messenger you can hand to someone who doesn’t want to pair a phone at all.

Firmware Status

Meshtastic: support landed in the 2.8 series, and the current build is 2.8.1, still an alpha. The latest stable release, 2.7.26, has no L2 build. In the web flasher it’s the “Seeed Wio Tracker L2” target, and Seeed’s guide uses “Full Erase and Install.” It runs Meshtastic’s color touch UI by default, and you can switch it to the simpler BaseUI from the device.

Two things to know before you flash:

• A wrong radio setting (the TCXO voltage) in early 2.8.0 builds was fixed in 2.8.1.
• Fixes for an ESP32 light-sleep crash and for the wake button, shutdown and touch gestures were merged after 2.8.1, so they aren’t in any release yet. If you’re buying now, the next 2.8 build should be the better one to run.

Seeed’s own guide also warns not to reboot or power off the device while it’s transmitting or saving settings, and to do a full erase and reflash if it starts rebooting on its own. 2.8 also changes several Meshtastic defaults, so read our 2.8 overview before you set it up.

MeshCore: not supported in a release yet. We’ve submitted the port ourselves: a pull request that adds companion, repeater and room server builds, and a second one for a standalone touch interface. Both are waiting on review, and the MeshCore maintainers may ask for changes or turn them down. The hardware is also pre-release, so its pin map may still change. Until a MeshCore release includes it, treat the L2 Pro as a Meshtastic device.

Who This Is For

If you want a node that works on its own, with messages, a map and a keyboard on one screen, the L2 Pro is the most complete package Seeed has made. It’s a good fit for a family member who won’t pair a phone, a vehicle or a base station on a desk, or anyone who wants offline maps in the field.

If you want the smallest, longest-running pocket node, the L1 Pro is still the one. And if you want the L2 Pro, it’s worth waiting for the next Meshtastic build with the fixes above.
