Jetson Nano Dev Kit Comparison

Jetson Nano Developer Kit (B01)
Jetson Nano Developer Kit (B01) is the official N-VIDIA kit with a variety of onboard interfaces including the 40PIN GPIO expansion header, Gigabit Ethernet port, USB 3.0 ports, HDMI port, DIS port and CSI camera connector. The B01 kit onboard is a non-production specification Jetson Nano module, mainly for development and software testing

Waveshare Jetson Nano Dev Kit
Waveshare Jetson Nano Dev Kit is the alternative solution of B01 kit, with the Jetson Nano B01 eMMC version module and the Waveshare JETSON-IO-BASE-A carrier board, providing almost the same performance and appearance as the Jetson Nano Developer Kit (B01). The Jetson Nano B01 eMMC version is more suitable for users to integrate in production environments.

Intelligent Dual-controller Design

The host controller adopts Jetson Nano Dev Kit, provides two version options: N-VIDIA Jetson Nano Developer Kit (B01) and Waveshare Jetson Nano Dev Kit. Both kits have almost the same performance and appearance, except that the Waveshare Jetson Nano Dev Kit adopts a 16GB eMMC version of the Jetson Nano Module. The Jetson Nano Dev Kit is equipped with 4GB memory and has better performance, responsible for Artificial Intelligence (AI), speech processing, visual processing, mapping and navigation, etc.

The sub-controller uses the Raspberry Pi RP2040 dual-core microcontroller, which has better real-time performance and higher control accuracy, and is responsible for attitude data collection and motion control.

Adopting USB communication, Transmission Speed Faster than the UART

Developed Based on ROS

ROS (Robot Operation System) is an open-source operating system that includes a collection of software libraries and tools for robot design. It provides the services expected of an operating system, including hardware abstraction, bottom layer device control, implementation of common functions, message transfering between processes, and package management. ROS simplifies robot design and is the mainstream robot software framework in the world.

Support I2C Slave Mode Control

Completely Compatible with Original JetBot Demo

The expansion board supports I2C slave mode control without porting and completely compatible with NVIDIA JetBot open-source project program, easily realizing AI functions such as obstacle avoidance and auto line tracking.

SLAM Lidar Mapping

Mapping with odometer, IMU, lidar, EKF, etc.
Supports Gmapping, Hector, Karto, and Cartographer mapping algorithms

Path Planning, Autonomous Navigation,
Dynamic Obstacle Avoidance

Adaptive Monte Carlo Localization (AMCL)

Move_base Autonomous Navigation

Supports single-point navigation, multi-point patrol navigation, and mapping while navigating

Single-point Navigation
After publishing the navigation target position, the robot will automatically plan the path to navigate to the target position.

Multipoint Patrol Navigation
Add navigation dots, the robot will cruise and navigate between the navigation dots.

Mapping while navigating
After publishing the navigation target position, the robot will automatically explore the path to the target point, and publish it while scanning the map.

OpenCV Vision Processing

Integrates OpenCV vision library, with extensive algorithm demos

Intelligent speech Processing, Human-robot speech Interaction

Supports remote Speech intercom, Speech synthesis, Speech detection, Speech recognition, human-computer Speech interaction

Real-time remote speech transmission, allowing robots to deliver conversations

Real-time speech transmission between the computer and the robot, enables two-way remote communication

Speech synthesis playback, let the robot speak

Convert text to natural, smooth vocals and play
Send a text topic to the robot, and you can hear it talking

Speech detection to let the robot know I'm speaking

Detects the sound of the audio stream and removes the mute part
Only take the part that the person speaks

Speech recognition, let the robot understand what I say

Recognize audio as text

Block diagram

High-power Encoder DC Gear Motor

High-quality carbon brushes, all-metal gear structure, high precision, low running noise, 11-wire AB-phase Hall speed encoder, support PID closed-loop speed control to calculate wheel odometer information

IMU Sensor

Built-in high-precision 9-axis motion attitude sensor, using extended Kalman filter to merge wheel odometer and IMU data, can produce higher-precision robot attitude

360 Degree Laser Ranging Lidar

360-degree scanning and ranging of the surrounding environment to obtain a contour map around the robot

8MP 160 FOV Camera

IMX219 Sensor, 3280 X 2464Resolution
Suitable for OpenCV vision development, object recognition, target tracking, automatic driving and other AI functions

Using USB Audio Chip

Onboard two high-quality MEMS silicon microphones and dual speakers for stereo recording and playback
So the robot also has "ears" and "mouths" that can "listen" and "talk". Easily realize intelligent speech interaction

Safe & Stable Circuit Design

Onboard battery protection circuit for preventing overcharge, over-discharge, overcurrent, short circuit proof, with reverse proof, and equalizing charge. Makes your operation more stable and safer. Built-in battery detection circuit, onboard OLED to real-time display the battery voltage, current, and remaining battery capacity.

SAFETY CAUTIONS

• Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage, if they're not properly recharged or used.
• Do not reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery.
• Do not mix use old batteries with new ones, avoid using batteries of different brands.
• When buying Lithium battery, should always make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test.
• Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first.
• Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.
