While searching AliExpress, I found the WiFi LoRa 32 (V4) shell set, another ESP32-S3-based off-grid LoRa/Meshtastic communicator designed for long-range wireless applications. Compared to devices like Blackout Comms, Wio Tracker L1 Pro, and ThinkNode M2, this device features built-in solar charging, optional GNSS, a removable battery, and a higher transmit power. The device features a high-power SX1262 LoRa transceiver with up to 28 ± 1 dBm transmit power, along with integrated Wi-Fi and Bluetooth 5/Mesh connectivity. It adds solar charging, an 8-pin GNSS connector, upgraded battery management, gold-plated 40-pin headers, and a fully protected 0.96-inch OLED, as well as a few I/Os for expansion. The USB-C port includes ESD and short-circuit protection, while dual IPEX connectors support both LoRa and 2.4 GHz antennas. Heltec WiFi LoRa 32 (V4) specifications: SoC – Espressif Systems ESP32-S3 CPU – Dual-core 32-bit microcontroller @ 240MHz Memory – 512KB SRAM, 2MB PSRAM Storage – 384KB ROM […]
