NUC7 Board Serial Hardware Specifications

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!

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.
