We recently acquired a NVIDIA Jetson nano developer's kit. It's a great, low power, single board computer with plenty of CPU and GPU performance.

The GGLABS T232 is very popular for debugging legacy RS-232 connections. In this article we will describe a few debugging tips and show how to emulate some of the common cable configurations.
