Use Spacers for NPTHs

During the use of VisionFive 2 Lite, avoid contact with hard objects that may cause damage. StarFive recommends that you use spacers for the following NPTHs (Non Plating Through Hole):

Figure 3. NPTHs on VisionFive 2 Lite
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

The following table lists the electrical specifications for VisionFive 2 Lite .

Area Specification
Input Power

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

  • USB Type C 5V/3A
  • 5V Power from PoE Header
  • 5V Power from the GPIO Pin 2 and 4
GPIO Voltage The required voltage level for all GPIO pins is 3.3 V.

Temperature Range and Thermals

The recommended ambient operating temperature range is from 0℃ to 50℃.

To reduce thermal output when idling or under light load, VisionFive 2 Lite reduces the CPU clock speed and voltage. During heavier load, the speed and voltage (and hence thermal output) are increased. The internal governor will throttle back both the CPU speed and voltage to make sure the CPU temperature never exceeds 85℃.

VisionFive 2 Lite will operate perfectly well without any extra cooling and is designed for sprint performance - expecting a light use case on average and ramping up the CPU speed when needed (for example, when loading a web page). If a user wishes to load the system continually or operate it at a high temperature at full performance, further cooling may be needed.

GPIO Pinout

VisionFive 2 Lite uses the same GPIO header as VisionFive 2. See the following diagram for the VisionFive 2 Lite GPIO pinout.

Figure 8. Pinout Diagram

Each GPIO pin can safely draw a maximum current of 32 mA, whereas the maximum current draw when all GPIOs are combined should be less than 100 mA. Take this into account, otherwise, you end up destroying the GPIO pins.

All GPIOs can be configured to support different functions including but not limited to SDIO, Audio, SPI, I2C, UART, and PWM. As VisionFive 2 Lite uses the same GPIO header as VisionFive 2,see Configure and Debug with 40-Pin Header for VisionFive 2 Lite GPIO configuration.

1 Short these pins before powering on the board to force entry to the U-Boot Fastboot mode on startup.
