Semtech SX1262 ESP32 22 dBm

Das RAK3112 von RAKwireless ist ein stromsparendes WisDuo-Modul mit großer Reichweite, das auf dem Espressif ESP32-S3 MCU mit integriertem Semtech SX1262 LoRa-Transceiver basiert. Es unterstützt LoRa, BLE und Wi-Fi und ist damit vielseitig für IoT-Anwendungen wie Heimautomatisierung, Sensornetzwerke und Mesh-Netzwerke (z. B. Meshtastic/MeshCore) einsetzbar. Das Modul bietet 16 MB Flash und 8 MB PSRAM, eine programmierbare Sendeleistung bis +22 dBm sowie mehrere Schnittstellen (UART, I2C, SPI, ADC, GPIO). Es wird ohne Standard-Firmware ausgeliefert und über Arduino, ESP-IDF oder PlatformIO programmiert. Zwei Varianten sind verfügbar: mit MHF4-IPEX-Antennenanschluss oder mit RF-Pinout für eine kundenspezifische Antenne.

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
