ThinkNode M2 Mini Meshtastic ESP32-S3 with OLED without case

The ThinkNode M2 from Elecrow is a compact LoRa signal transceiver, specially developed for building decentralized Meshtastic networks. The main processor is an ESP32-S3 module with Xtensa 32-bit LX7 dual-core and up to 240MHz clock frequency, supplemented by 512KB SRAM, 8MB PSRAM, 4MB flash, and 384KB ROM. A Semtech SX1262 transceiver is installed for LoRa communication, supporting the 868MHz band (EU) and connecting an external antenna via an IPEX antenna connector. A 1.3-inch OLED display with 128 × 64 pixels displays device data and status in real-time. The module is pre-installed with the Meshtastic firmware and fully compatible with the official Meshtastic app. The compact board without a case measures only 51.5 × 37 × 9.5 mm and is therefore ideal for integration into own projects and custom solutions.

Recommended Accessories:

• LiPo Battery JST 1.25

Features:

• ESP32-S3 dual-core with 512KB SRAM, 8MB PSRAM, and 4MB flash provides sufficient power for Meshtastic applications and own extensions
• LoRa communication on 868MHz with Semtech SX1262 transceiver and IPEX antenna connection enables mesh networks over long distances
• 1.3-inch OLED display with 128 × 64 pixels and SH1106 driver shows status, messages, and configuration directly on the device
• WiFi 802.11 a/b/g/n and Bluetooth 5.0 LE allow configuration and data transfer via mobile devices and the official Meshtastic app
