Produs terminatview
The MINIX B21 system consists of two main components: the Transmitter (TX) and the Receiver (RX).
Transmițător (TX)
The Transmitter (TX) connects to your source device (e.g., laptop, smartphone, tablet) via a USB-C port. It captures the video and audio signal and transmits it wirelessly to the Receiver. Each TX unit features an indicator light and a function button.

Receptor (RX)
The Receiver (RX) connects to your display device (e.g., TV, monitor, projector) via an HDMI port. It receives the wireless signal from the TX unit and outputs the video and audio. The RX unit requires external power, typically supplied via a USB-C port connected to a power adapter (5V, current above 2A).
