Paper Mesh

Heltec Wireless Paper (Paper Mesh)

Intro: The Wireless Paper is Heltec’s e‑ink variant of their LoRa boards, built for Meshtastic. It combines the ESP32 MCU with the SX1262 LoRa transceiver and a 2.13″ e‑ink screen, making it ideal for low‑power, always‑visible status displays in a mesh network.

Key Features:

  • MCU: ESP32‑S3FN8 with Wi‑Fi and Bluetooth support
  • LoRa Transceiver: Semtech SX1262
  • Frequency Options: 433 MHz, 470–510 MHz, 863–870 MHz, 902–928 MHz
  • Display: 2.13″ e‑ink screen (black/white, ultra‑low power)
  • Connectors: USB‑C for power/programming, U.FL/IPEX antenna connector
  • Form Factor: Slim board with acrylic protection option
  • Power: SH1.25 battery connector for external Li‑Po packs

Considerations:

  • Screen support varies by firmware version — some revisions (e.g., V1.1.1) had issues with e‑ink compatibility.
  • No case included — operators often need to 3D‑print or adapt enclosures.
  • Best for fixed or semi‑portable nodes where low‑power display is useful (status, packet counts, node ID).
  • Not as rugged as Station‑class devices — better suited for hobbyist or indoor deployments.
  • Affordable option (~$17–20 on AliExpress) compared to OLED boards.
