The Heltec WiFi LoRa 32 (V4) is an ESP32-S3-based off-grid LoRa/Meshtastic communicator with solar charging, optional GNSS, and a high 28dBm transmit power.
LILYGO has announced a raft of new microcontroller development boards targeting different niches: a low-frequency LoRa board, an ultra-widescreen display board, a LoRa-equipped ePaper display board, and a CAN bus board. The boards are powered by the Espressif ESP32-S3 microcontroller.
Meshtastic is an open-source project that provides long-range, off-grid communication using inexpensive LoRa radios. It allows users to send text messages, GPS locations, and voice messages over long distances without relying on internet or mobile networks.
It is a 4-inch touchscreen device designed for Meshtastic®, powered by dual MCUs, the ESP32 and RP2040, and supports Wi-Fi, BLE, and LoRa®. It is an open-source, powerful IoT development platform.
The T-Deck is a compact device with a 2.8-inch IPS LCD touch screen, integrated keyboard, trackball, microphone, and speaker, running on an ESP32-S3 dual-core processor. It supports various frequencies and includes a GPS module and battery in its Plus variant. It features a U.FL/IPEX antenna connector for LoRa and can be flashed using Espressif's firmware download mode.
