openSPOT4 Pro
🛒 Buy now!The openSPOT4 Pro is our latest battery powered, portable, standalone digital radio internet gateway (hotspot) designed mainly for amateur radio use. You can talk with others on digital radio networks by using an openSPOT4 Pro, Wi-Fi internet access, and your digital transceiver.
Our team has completely redesigned both the hardware and software, with a multicore CPU and a completely new Wi-Fi module, which means both the web interface and update downloads are blazing fast. The built-in battery has a larger capacity, and the device can work much longer than our previous battery-powered models thanks to the new hardware and optimized software.
