For spacers, StarFive strongly recommends that you use the copper columns or studs with the following specifications:

  • Single head hexagonal copper columns (Size: M2.5*10+6mm)
    Figure 4. Single head hexagonal copper columns
  • Double way hexagon copper studs (Size: M2.5*4)

Electrical Specification

VisionFive 2 supports various ways of powering, smart power adapter as well as fixed voltage:

  • USB PD 2.0
  • Support USB Type C PD 2.0, 9 V/2 A, 12 V/2 A, 15 V/2 A, 20 V/2 A
  • Qualcomm® Quick Charge™ 2.0
  • Support QC3.0/2.0 adapter, 9 V/2 A, 12 V/1.5 A
  • Power adapter with fixed voltage from 5 V to 20 V on the USB C power port
  • 5 V Power from the GPIO Pin 2 and 4
Note: The USB Type C port on VisionFive 2 is used for power supply only. To avoid power surge, which may trigger power-surge protection and deteriorate the board performance, make sure the board is fed by one power source at a time. Use USB port for data transmission, DO NOT reuse this port for both power supply and data transmission.

The required voltage level for all GPIO pins is 3.3 V.
