Heltec Vision Master E213

Heltec Automation

868/915 MHz MHz SX1262 ESP32

Der Heltec Vision Master E213 (HT-VME213) ist ein kompaktes Entwicklungskit auf Basis des ESP32-S3R8-Mikrocontrollers mit einem 2,13-Zoll-Schwarz-Weiß-E-Ink-Display (250 x 122 Pixel, Teilaktualisierung unterstützt). Er bietet Wi-Fi, Bluetooth (BLE) sowie ein optionales LoRa-Modul mit SX1262-Chip und ist mit Open-Source-Projekten wie Meshtastic kompatibel. Dank sehr niedrigem Stromverbrauch (20 µA im Deep Sleep) und E-Ink-Display, das den Inhalt bis zu 180 Tage ohne Strom hält, eignet er sich besonders für batteriebetriebene IoT- und LoRa-Mesh-Anwendungen. Ein integriertes Batteriemanagement (SH1.25-2-Anschluss) und zwei SH2.0-4P-Sensorschnittstellen erweitern die Einsatzmöglichkeiten.

Repeater v1.15.0-evo_0.1.21 17.03.2026 Release

⚠️ Check that radio.rxgain(on) and flood.advert.base (0.308) are set correctly after flashing! ⚠️

This build is based on official MeshCore 1.15.0 dev branch (as of 25-May-2026 and additionally includes the following unmerged upstream PRs/changes:

Additional changes:
  • Flood adverts are disabled (flood.advert.interval set to 0) by default
  • :new: modified PR1810 to not block flood adverts but only PAYLOADTYPEGRPTXT and PAYLOADTYPEGRPDATA so that some limited flood advert distribution can be managed via PR2553 to support e.g. observer maps.
Changelog:
  • Based on dev v1.15.0 as of 25-May-2026

BLE Companion pre-release-Heltec-E213-Wireless-Paper-E290 11.06.2026 Release
v1.16_0611 pre-release for Heltec E213, Wireless Paper and E290
  • New device: Heltec Vision Master E213 — full support (Companion, Repeater, Room Server).
The Heltec Vision Master E213 is now fully supported. It is an ESP32-S3 based board with a 2.13" e-ink display, SX1262 LoRa radio, and a USB-C port. The complete companion UI runs on the e-ink display — Quick Send, Contacts, Settings, Saved Locations, GPS Trace, and message preview. Repeater and Room Server firmware are also provided.

Notable characteristics:

  • Always-on e-ink display — no screen timeout; the display retains its content indefinitely without power.

  • Native multilingual text — Latin, Cyrillic, and Greek scripts render natively.

  • I2C sensor support — environment sensors (temperature, humidity, pressure...) can be connected via the QuickLink I2C port.

  • Two user buttons — the second button (GPIO21) makes navigation faster: press it to scroll up in any list, or to go back/exit any menu.

  • New devices: Heltec Wireless Paper and Heltec Vision Master E290 — full support (Companion, Repeater, Room Server).

Two new e-ink boards are now supported:
  • Heltec Wireless Paper — ESP32-S3 with a 2.13" e-ink display (same resolution as E213), SX1262 LoRa radio, and a compact form factor. Shares the same companion UI and firmware variants as E213.
  • Heltec Vision Master E290 — ESP32-S3R8 with a larger 2.9" e-ink display (296×128), SX1262 LoRa radio, and a QuickLink I2C port for external sensors. The companion UI adapts automatically to the wider, taller display — showing more message lines and better-spaced layouts compared to the 2.13" boards.
