Battery – The newer hub uses a compact Lithium-ion battery, whereas the older EV3 hub uses four AA batteries.įor a more detailed comparison of the newer Large Intelligent Brick and older EV3 Intelligent Brick, there’s a whole section dedicated to this in my review of #45678 Spike Prime.Screen – The new hub has a bright 5×5 pixel screen, while the older EV3 hub has a dim black-and-white 178×128 pixel LCD display.RAM – The newer hub has 1/200 as much RAM.īut it is on the CPU die and likely very fast.⅓ of the raw Clock Speed, but about ½ the speed when benchmarked due to newer CPU architecture. CPU – The newer hub has a slower CPU than the older EV3.OS – The newer hub uses a lightweight embedded OS which boots almost instantly, while the older EV3 hub runs Linux and takes 30-seconds to boot.Size – The newer hub is about ½ the size & weight of the older EV3 hub.LEGO Technic Small Hub Technical Specifications,, Retrieved Nivember 6, 2021.Powered Up Move Hub,, Retrieved June 13, 2020.Technic Large Hub Technical Specifications,, Retrieved June 13, 2020.Technic Hub Specifications,, Retrieved June 13, 2020.This hub can only be programmed to run your app autonomously using custom firmware provided by the open-source Pybricks project.Gyro Sensor, Power Button, & Single LED.ĥ×5 LED Display, Gyro Sensor, & Speaker. The unofficial PyBricks firmware enables autonomous programs using other Bluetooth hubs on this list. When using the official Spike or Mindstorms apps provided by The LEGO Group, the Large or Small Intelligent Hub also allow you to send your program to the hub and have it continue to run ‘autonomously’ after disconnecting from Bluetooth. Using the software provided by LEGO, the program you write (using your Phone, Tablet or PC) will only continue to run when it remains connected to the Hub via Bluetooth. Autonomous – Programs can be uploaded to the Hub, allowing it to take actions without being connected to another device.Īll of these hubs (except the Battery Box) allow you to create a program which causes your machine to take actions, often in response to information received by one or more sensors. USB – You can connect the hub to your PC using USB.Bluetooth (BT) – You can connect most of these hubs to your Phone, Tablet, or PC by installing the appropriate app on your device.Voltage – This depends on the number of batteries used, or the design of the rechargeable battery pack.Power Source – What type of battery does it use, and how many.Number of ports – With more ports, you can connect more sensors and motors.Physical Size – The smallest hub is 7×5×4 and the largest is 7×11×4.Powered Up hubs vary in some important ways: Now, let’s look at all of these components in a lot more detail! Powered Up HubsĪll of the motors and sensors in this guide require a Powered-Up hub to get things moving (and to write custom programs). Accessories – There are a few lights you can attach to your model, as well as a Bluetooth remote if you do not want to use your phone or PC.Some of the high-end hubs have some sensors built in, and additional sensors can be attached via the Powered Up connection. Sensors – Powered-up Sensors allow your program to respond to the environment.They come in a range of sizes and features, and some are optimized for building System models (studded connections) while others are optimized for building Technic models. Motors – Powered-up Motors add motion to your creations.Most allow you to run a program provided by the LEGO group for a specific set, or to write your own custom apps. Hubs – Powered-up Hubs provide power to motors and accessories.Now that The LEGO Group has completed their transition to the Powered Up system, we have a robust selection of hubs, motors, and accessories: To celebrate the transition to the new Powered Up system, I’ve added labels for these Powered Up components to LEGO Brick Labels v36 or newer. The latest version includes labels for these Powered Up components.
