Leetop has introduced two carrier boards for NVIDIA Jetson Nano or Xavier NX modules, with Leetop A205 a full-featured carrier board offering five SATA ports, six MIPI CSI camera interfaces, an M.2 Key E slot, dual Gigabit Ethernet, four USB 3.0 ports, dual HDMI output and more, as well as the more compact Leetop A203 about the size of the modules themselves and offering Gigabit Ethernet, HDMI output, USB 3.0/2.0 ports, a camera interface, and an M.2 slot for optional WiFi and Bluetooth connectivity.
We’ll focus on the former in this article, as it offers more features, and the smaller board provides less functionality than the NVIDIA Jetson Nano developer kit at a much higher price, although I understand it can still be useful for space-constrained applications.
