Hi, I am planning to develop an enclosure to the ZUBoard-1CG & would like to add a fan.
I want the fan to be powered ON as soon as the board gets the power through USB-C.
For this, I plan to use USB fan which draws less current & connect it to USB port of the ZUBoard-1CG
Can I connect?
Noctua NF-A4x10 5V
Input power (typical) 0.3 W
NF-A4x10 5V PWM: Specifications | Noctua
OR please let me know if there is some fan which is already tested with ZUBoard-1CG
Thanks,
Madhu
I don't believe a FAN has been tested, but the USB2.0 port is powered with 5V that gets generated from +SINK_PWR and is sequenced with EN3 signal. Because it is sequenced, the board will need to powered-on before the fan will turn on, ie - simply plugging in USB-C may not power the fan. There is a mode where plugging-in USB-C is possible to power-on the board skipping the push-button. A resistor would need to be moved on the board. See the INIT signal on the power controller and the gray box. This would allow the fan to turn on (and the board) when plugging in the USB C cable directly.
