Features: 1. Onboard 7-way USB expansion port, compatible with USB2.0/1.1 transmission. 2. Using industrial- HUB chip, using MTT technology, 7-way USB is more stable and to use at the same time3. Each USB port has ESD protection, the device connection is from power surge damage and data loss4. The on-board overvoltage protection circuit can effectively prevent the equipment from being damaged due to the access of other high-voltage power sources.5. On-board multiple protection circuits: overvoltage protection, overcurrent and short circuit protection, overtemperature protection, reverse current protection, undervoltage lockout, 8KV ESD protection, filter protection, etc. 6. There are multiple LED indicators on the board, which is convenient to check the working status of the power supply and USB interface7.
