TinyGateway WiFi

TinyGateway WiFi is a low-power and low-cost Bluetooth LE gateway, with WiFi connectivity.
TinyGateway WiFi is based on ESP32 S3 embedded SoC, which includes WiFi 802.11 b/g/n , and Nordic nRF52832 SoC for Bluetooth LE scan and connection. It is able to scan for any Bluetooth LE advertising packet, including main beacon technologies, iBeacon and Eddystone. Both HTTP and MQTT protocols are available for network communication.
TinyGateway WiFi is provided in a compact light-weight plastic enclosure suitable for wall or ceiling installation. Dual power-supply is supported: 5VDC USB (through lateral USB-C connector) or 4.5-30VDC (through internal 2-port connector, with rear knockout on back panel for cable entry).
