Firmwares
The reference MeshCore build plus community forks and custom variants — with node roles and the devices they run on.
Universal firmwares 10
Built to run across many boards and device families.
MeshCore (Reference)
The reference MeshCore firmware — a lightweight C++ library and firmware for multi-hop packet routing over LoRa radios. It powers decentralized, self-healing mesh networks for off-grid, emergency and tactical communication, with prebuilt images and a web flasher.
EasySkyMesh
A power-saving oriented MeshCore firmware with experimental, advanced features and bug fixes aimed at ultra-low-power repeater and sensor deployments. Targets extended battery life (e.g. ~16µA power-off) with the intent of upstreaming improvements into MeshCore.
Meshcomod
A multi-transport companion firmware built on MeshCore that exposes USB, Bluetooth and TCP connectivity simultaneously, so phones, web clients and Home Assistant can all talk to one radio at once. Adds runtime Wi-Fi config and an on-device UI.
LusoFW
A community MeshCore firmware distribution for the Portuguese community, with Portugal-oriented radio defaults, duty-cycle enforcement, network time synchronisation, flood-advert controls, and curated repeater and bridge builds.
MeshCore Low-Power
A power-optimised MeshCore firmware with deep sleep, a full companion display UI with multi-transport connectivity (BLE + USB + WiFi in a single build), advanced radio and network controls, a browser-based configuration portal, and battery-life profiling — built for multi-day off-grid operation.
MeshCore Solo
A fork of the reference MeshCore companion radio firmware with extended features and UI enhancements. Adds GPS navigation (waypoints, compass, trail recording with GPX export), battery power-saving (hardware RX duty-cycle + adaptive power control), favourite contacts dial, extended language support with native Unicode rendering, message delivery status, screen lock, auto-reply bot, repeater mode with diagnostics, and more — all optimized for joystick-only navigation on small displays.
MeshCoreNG
A "Next Gen" fork of MeshCore developed in the Netherlands, focused on making repeaters smarter so larger, busier meshes stay stable. It adds a dense-mesh foundation — flood-advert forwarding control, congestion/density stats, hardware CAD channel-busy detection, node-based retransmit spreading and duplicate-hearing suppression — plus an optional internet bridge for linking isolated RF islands, all while staying protocol-compatible with existing MeshCore clients.
Offband Mesh
A MeshCore fork for cross-role firmware enhancements and optimization. Active roles include companion/observer with WiFi+MQTT observation publishing, NimBLE migration, web UI, and repeater with MQTT-to-Mosquitto bridging, burst-WiFi telemetry, heap and power tuning.
ZephCore
A ground-up port of MeshCore from Arduino to the Zephyr RTOS. Replaces the Arduino loop with Zephyr's event-driven primitives so the CPU sleeps between events, while aiming for full protocol compatibility with stock MeshCore firmware and the MeshCore mobile apps.
MeshCore-Evo
An improved repeater-focused fork of MeshCore that bundled pending upstream PRs and improvements for dense meshes — notably flood-advert traffic mitigation and enhanced denyf * handling. Largely superseded once reference 1.16.0 added native flood traffic management.
Platform-specific firmwares 2
Built for a particular chip or platform family.
ESP32 2
EastMesh
EastMesh firmware builds for MeshCore, with MQTT repeaters, WiFi companions, and simple release downloads for supported boards. Features an optional local HTTPS config panel on supported ESP32 targets, JWT auth using device identity, and battery reporting.

Touch UI 4
Meck
A MeshCore companion firmware fork focused on enabling BLE and WiFi connectivity for the LilyGo T-Deck Pro, T-Deck Max, and T5 E-Paper S3 Pro. Features a full touch UI with on-device keyboard, games, voice notes over LoRa, web browser, SMS, and a configuration launcher with OTA updates.
MeshCoreTerm
A retro-themed companion firmware based on MeshCore, featuring a rich on-screen keyboard, hardware navigation (D-pad, joystick, trackball), management features for device name, WiFi, BLE PIN, radio parameters, and GPS configuration. Supports multiple devices with prebuilt binaries and no online update requirement.
Wadamesh
A touch-UI MeshCore firmware for the LilyGo T-Deck / T-Deck Plus and Heltec V4 TFT (ESP32-S3), built with LVGL. Split out from meshcomod. Provides a full touch-driven companion experience with on-screen keyboard and WiFi connectivity.
MeshcoreGRID
Touch-first MeshCore handheld firmware with a standalone GRID interface for chat, discovery, contacts, radio controls, BLE settings and power management.
Multi-boot 2
Mesh Loader
Dual-boot loader that installs patched MeshCore and Meshtastic images in separate ESP32 partitions and lets the user switch firmware at startup without reflashing.
Heltec V4.2 Multi-Boot
Boot selector firmware for Heltec WiFi LoRa 32 V4.2 that installs and switches among MeshCore, Meshtastic, RNode or other firmware images while preserving separate settings and filesystem data for each slot.
Tracker 2
FieldMesh
A MeshCore firmware fork optimized for outdoor use — festivals, hiking, off-grid events. Adds automatic GPS advertising, dedicated tracking page with distance calculation, Off-Grid mode with legal frequency defaults and one-press toggle, SOS system with buzzer alarms, message history with RAM ring buffer, and text input/send on joystick-equipped devices. Designed to be field-ready: put it in your backpack and trust it's doing its job.
TapTap Firmware
MeshCore fork for small tracker-style devices, adding button-driven canned messages, Morse-code entry, audible alerts and remote text commands for screenless operation.
