USBridge Sig was build using RPI compute module so from a software point of view, this will give you access to the latest kernels (way ahead of any competitor). The focus of the device is to lower the noise on USB bus. We chose an excellent USB hub IC (TI) and a separated Ethernet to USB IC (Axis).

To lower the noise of the USB, we had to lower noise on EACH rail. In total, USBridge Sig uses more than 30 LDOs. Even the SD card power rail has a dedicated LDO. There are zero switching elements on board.

Of course, since this is based on RPI compute, we decided to include the standard RPI connector. Anything that works on an RPI will work on the USBridge Sig. For example, you can use a DigiOne / DigiOne Sig to make a full fledge streamer that outputs USB, BNC and coaxial.
