  • Does not support pure high-speed USB 2.0 devices

Isolation Voltage and Speed

The BUCIER ADUM3160 B0505S provides 1500V isolation between a USB host and a peripheral. It draws power from the host port and operates at 12 Mbps full speed and 1.5 Mbps low speed. The module uses an onboard B0505S 1W supply and suits industrial or noise-sensitive environments.

Supported and Unsupported Devices

It works with low-speed keyboards, mice, USBASP and HID or CDC devices, plus full-speed flash drives using FT232, CP2102, PL2303 or CH341 chips. It does not support pure high-speed equipment such as USB wireless network cards or some USB 3.0 devices. Buyers needing high-speed throughput should look elsewhere.

Power Budget Limit

The onboard supply delivers 1W, so the isolator reliably powers devices drawing up to 180 mA. For peripherals exceeding that current, a dual-headed USB cable with an external power source is required. This current ceiling is the single figure that decides whether the module fits a given device.

Questions about this item

What does the 12 Mbps full-speed rating mean for my connected USB device?

It lets low-speed 1.5 Mbps and full-speed 12 Mbps peripherals such as keyboards, mice, flash drives with FT232, CP2102, PL2303 or CH341 chips, and USBASP programmers operate through the isolator.

Which USB standard does the ADUM3160 isolator implement and what speed ceiling does that impose?

The module follows the USB 2.0 low-speed and full-speed specifications, so it passes 1.5 Mbps and 12 Mbps traffic but blocks pure high-speed devices.

What physical space and power budget must I allow for the B0505S module inside my enclosure?

The blue PCB draws up to 1 W from the host USB port; if the downstream device needs more than 180 mA, add a dual-headed cable for extra power.
