 The 128-core Maxwell GPU supports OpenGL 4.6, OpenGL ES 3.2 and Vulkan 1.1 as well.
-==Jetson Nano vs Jetson TX1==
+==Jetson Family Comparison==
-Nano and TX1 are not pin compatible, however, they share common features, like USB 3.0 and CSI. Both come with the same size of eMMC and memory. Encode/decode capabilities also remain the same. While TX1 has 256-core GPU, Nano comes with 128-core, both NVIDIA Maxwell GPUs. Nano CPU has a lower frequency of 1.43 GHz compared with TX1 CPU frequency of 1.7 GHz. The differentiator of the Jetson Nano with respect to other boards in the Jetson family is its low power consumption, it requires an input voltage of 5 V while TX1 input voltage vary between 5.5 V and 19.6 V.

+====Compatibility with Jetson AGX Xavier====
+An alternative to start developing for Jetson Xavier NX is using the Jetson AGX Xavier Developer Kit. You just need to download [https://developer.nvidia.com/embedded/downloads#?search=Jetson%20AGX%20Xavier%20as%20Jetson%20Xavier%20NX%20Emulation%20Package this software patch] and install it on your Jetson Xavier AGX Developer Kit.
