High-Performance IR Transmission
Equipped with two VSMY294310SL high-speed, high-range 940nm infrared LEDs. Thanks to their angled placement, the board provides a wide ~100° angle, enabling control across a large area. -
Wi-Fi Smart Home Integration
Powered by the ESP32-C6, enabling seamless integration with Wi-Fi networks and smart home platforms (e.g., Home Assistant, OpenHAB, etc.). -
Multiple Power Options
- USB-C for power and data (direct USB connection to the ESP32-C6).
- CR123A battery holder for portable, untethered operation.
- Power source selection switch allows users to toggle between USB and battery.
