NUC7 Board Serial Hardware Specifications

[AMuro1]

I would like to connect a hardware peripheral with a 3.3V TTL (5V tolerant) UART to the serial port of a NUC7 board (BLKNUC7i7DNBE). I've read all the documentation I can find that appears to be relevant. The only information I have on the hardware specs of the port is found in the data sheet for the BLKNUC7i7DNBE. It specifies that the Tx pin on the 9-pin serial port is 5V TTL, which is compatible with my device. It also specifies the Rx pin as RS232 and this is where I am unclear. Based on this I would expect that a TTL signal would not be compatible with the Rx pin.

Is there a Vh and Vl spec for the serial port or any further information that can help me determine compatibility with my 3.3V TTL device?

Thanks in advance!

Hello AMuro1,

Thank you for submitting your question on this Intel® Community.

We will be glad to do further research to address your request. 

What is the hardware peripheral you would like to connect to the Serial Port of the Intel® NUC Board NUC7i7DNBE?

I am looking to connect a pixhawk cube flight controller. See pg 17 of the datasheet for the uart (telem) specs here: ​http://www.hex.aero/wp-content/uploads/2016/07/DRS_Pixhawk-2-17th-march-2016.pdf

Hello AMuro1, 

We would like to post an update on this thread.

Based on the Intel® NUC Board NUC7i7DNBE specifications, if the Pixhawk Cube Flight Controller has a serial port, then it should work with your unit. However, our recommendation is that you can contact the EIA/TIA standards organizations for details on RS-232. You may also want to consult with the Pixhawk manufacturer.
