Devices Guide
The Devices page lists hardware LowMesh tracks—radios, MCUs, antennas, and features—so you can compare boards before you buy or flash.
How to read a device card
Each entry is built from a spec sheet (chipset, RF front-end, GNSS, display, etc.). Use it to answer:
- Which firmware families are realistic? (Meshtastic® and MeshCore™ do not support identical sets.)
- Which flash method applies? (ESP32 serial vs nRF52 UF2 vs RP2040 UF2.)
- What range class can you expect? (Antenna, power, enclosure, and environment dominate real-world results.)
Specs are informational—always confirm against current upstream device support for the firmware you plan to run.
MCU families (what matters)
ESP32 (including S3 and variants)
- Pros: Wi-Fi/BT radio for apps, large ecosystem, many off-the-shelf boards.
- Flashing: Serial bootloader via USB-UART or integrated USB; see Flashing Guide.
- Watch for: USB-UART vs native USB wiring, revision-specific pin maps, PSRAM requirements for some builds.
nRF52840 / nRF52 series
- Pros: Low power, strong BLE stack, common in compact trackers and keyboards.
- Flashing: Often UF2 or DFU; vendor tools may supplement the web flasher.
- Watch for: SoftDevice/bootloader interactions; follow Meshtastic® or MeshCore™ guidance for your exact board.
RP2040
- Pros: Simple UF2 drag-and-drop for many Meshtastic® targets.
- Flashing: BOOTSEL USB drive workflow; see Flashing Guide.
- Watch for: Wi-Fi is not native on RP2040—Wi-Fi boards add separate modules.
Radio and antennas
- Frequency band must match your legal region and antenna.
- Connector type (IPEX/U.FL vs SMA) and ground plane affect real range.
- Higher TX power increases heat and battery drain; it does not fix a bad antenna match.
Power and deployment
- USB is fine on the bench; field use needs battery chemistry, charging, and enclosure planning.
- Solar setups require charge control and realistic duty cycle expectations.
- Weatherproofing matters for condensation and corrosion—especially at antenna ports.
Choosing a device (practical checklist)
- Firmware goal – Meshtastic® community path vs MeshCore™ features.
- Form factor – handheld, vehicle, fixed repeater, or sensor node.
- GNSS – needed for position features; adds power draw.
- Display – useful for standalone use; impacts UI firmware choice (MeshCore GUI builds, etc.).
- Certification – regulatory markings depend on region, antenna, and modifications—do not assume hobby boards are certified for every use.
After you choose
- Purchase from Shop or a trusted retailer.
- LowMesh hardware ships with Meshtastic®—you can skip to Device Setup and the Meshtastic mobile app. Use the Flashing Guide only to update Meshtastic®, switch to MeshCore™, or match a specific build.
- Complete Radio & mesh concepts as needed; use the MeshCore guide if you flashed MeshCore™.
