VW80X Series Serial-WiFi Modem
VW801/2/3/4 low-power embedded Serial-WiFi modem series provides a way to use the popular serial
interface (RS485, USB virtual COM, 232TTL, RS232,) to transfer data over Wi-Fi wireless networking.
The module integrates hardware MAC, baseband chip, RF transceiver unit, and a power amplifier; the
embedded firmware supports flexible Wi-Fi protocols, TCP / IP protocol stack, as well as kinds of
networking configuration.
VW80X series integrate all wifi features in a compact size measure only 72mm x 24mm x 9mm.
Using a convenient solid USB connector, allowing the user plug into the user end equipment easily.
Module is equipped with built-in PCB antenna, no external antenna needs.
VW80X series modem looks clean and beautiful, suitable for the various embedded I.O.T applications.
