Developer Kit
The developer kit comes with a MIPI-CSI camera connector to enable video applications, as well as an ethernet port, HDMI output, and four USB ports. A 5V/4A source is required to power the kit. Other features offered in the development kit are:
- GPIO
- I2C
- I2S
- SPI
- UART
- Display port
The Jetson Nano developer kit requires an external chip for WiFi and/or Bluetooth and unlike other devkits in the Jetson family, it does not support USB OTG.
Developer Tools
Software development can be done using NVIDIA's Jetpack, as in other NVIDIA Jetson boards. The image generated by Jetpack can be flashed into an SDCard to boot Jetson Nano. Jetpack provides Ubuntu 18.04 OS with kernel 4.9, find the information about how to install JetPack in Related Documentation. For AI and parallel computing applications, Jetpack provides CUDA, cuDNN, and TensorRT. Additionally, tools like nvpmodel to control the power/performance profile and tegrastats that provide CPUs and GPU stats, come with the filesystem.
The 128-core Maxwell GPU supports OpenGL 4.6, OpenGL ES 3.2 and Vulkan 1.1 as well.
Jetson Nano vs Jetson TX1
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.
