3.5.
Power Supply Voltage
The 3.5‘‘-eIO-GPA is powered either by the DC input delivered from the single board comouter via the board-to-board
connector or by the input power supply delivered from a power supply unit via the 1x3-pin 3.5 mm pitch terminal
block located on rear I/O panel, which will be further delivered via the board-to-board connector to power the single
board computer. In case of the latter, the input power supply must monitor the supply voltage and shut down if the
supply is out of range -- refer to the actual power supply specification, in order to ensure safe operation of the 3.5‘‘-
eIO-GPA and the single board computer. Please note, in order to keep the power consumption to a minimal level,
boards do not implement a guaranteed minimum load. The input power supply delivered via the terminal block to the
3.5"-eIO-GPA must be within the range between DC 11 V and DC 32 V.
Hot Plugging power supply is not supported. Hot plugging might damage the board.
The requirements to the supply voltages are as follows:
