A browser-based USB flasher for Heltec WiFi LoRa 32 V4.2/V4.3 OLED boards, supporting MeshCore and Meshtastic firmware workflows.

Landing page captured for the 2026-09-15 issue.

Field notes

The flasher guides a user through board selection, USB connection, firmware installation, and recovery inside the browser. Its workflow covers both MeshCore and Meshtastic, with additional controls for boot-file repair, settings erasure, backup restoration, and log download. The page specifically warns that browser-stored backups can contain private keys, contacts, and Bluetooth credentials, while Linux users receive a device-path instruction for /dev/ttyACM0.
