vicliu624’s Trail Mate is an open-source firmware for off-grid communication and GPS coordinates sharing, leveraging the Meshtastic, MeshCore, and other projects, and designed for ESP32 handhelds such as LILYGO…
…This makes it very useful for energy-monitoring projects, such as reading SDM smart meters or interfacing with solar/battery systems. The project is partially open source, and you can find the…
…It also simplifies the prototyping workflow by integrating a WCHLink-E debugger directly onto the board, meaning you won’t need to wire up an external programmer to flash the MCU or…
…Like the previous model, it focuses on local operation and privacy, and supports integration with Home Assistant and Domoticz via MQTT autodiscovery, as well as Homey through the HomeyDuino app. It is…
Ivan Svarkovsky’s S3-MSX-PC open-source project implements a bare-metal MSX2+ emulator running on an ESP32-S3 microcontroller and outputting 64-color VGA via a simple R-2R resistor…
…supported by the Lime Suite NG driver stack and the wider SDR ecosystem with integration with projects such as SoapySDR, GNU Radio, Amarisoft 4G/5G, OpenAirInterface, and srsRAN. The company will also…
…While the ESP32-C5 C-ITS receiver board integrates an ESP32-C5-WROOM-1 module, a GPS module, and an Ethernet port with PoE, the V2X2MAP project leverages any recent Android smartphone…
…The device integrates a u-blox MIA-M10Q GNSS module for positioning, a SX1262 LoRa transceiver for long-range communication, and a Bosch BHI260AP smart sensor for motion-based AI applications. Additionally…
…It measures just 42 × 36 mm and squeezes multiple interfaces into a 15.1 cm² footprint, making it suitable for space-constrained applications such as robotics, IoT devices, and custom hardware integrations…
…But what is interesting is that, while it carries the Qualcomm brand, documentation from the Zephyr Project clearly shows that the QCC74x series is actually based on and mostly equivalent to the…
