What is LEGO Powered Up?

#51515 LEGO MINDSTORMS Robot Inventor

In recent years, they have also introduced simpler Bluetooth-connected products as part of their LEGO Technic and LEGO System product lines, which allow you to control motors and lights using a Phone or Tablet.

You can also use Powered Up Motors using the Bluetooth Speed Remote instead of a Phone or Tablet. More recently, they introduced the Technic Battery Box, which allows you to control two motors without a Bluetooth device at all.

LEGO Brick Labels (for Powered Up)

LEGO Brick Labels is a collection of around 1500 Labels for the most common LEGO parts. It includes labels for most LEGO Technic pieces, but I’ve avoided electronic components until now…

The latest version includes labels for these Powered Up components.

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.

Powered Up Components

Now that we are several years into the transition to the Powered Up system, we have a robust selection of hubs, motors, and accessories.

Powered Up Hubs

All of the motors and sensors in this guide require a Powered-Up hub to get things moving (and to write custom programs).

Powered Up hubs vary in some important ways:

• Physical Size – The smallest hub is 7×5×4 and the largest is 7×11×4.
• Number of ports – With more ports, you can connect more sensors and motors.
• Power Source – What type of battery does it use, and how many.
• Voltage – This depends on the number of batteries used, or the design of the rechargeable battery pack.
• Bluetooth (BT) – You can connect to most of these hubs using the appropriate app on your Phone, Tablet, or PC. (The Technic Battery box does not require or support Bluetooth.)
• USB – You can connect the hub to your PC using USB.
• Autonomous – Programs can be uploaded to the Hub, allowing it to take actions without being connected to another device.

Using the software provided by LEGO, you can write programs using a Phone, Tablet or PC and run the program while connected to the Hub via Bluetooth.

Most of these hubs also allow you to send your program to the hub and have it continue to run autonomously after disconnecting from Bluetooth, but this is only officially supported when using the Large or Small Intelligent Hub. (After the program is sent to the hub, your robot can take actions in response to information received by one or more sensors.) 3rd party PyBricks firmware can enable this functionality on other Bluetooth hubs in this list.

Hubs:

Powered Up Motors

There are seven standalone motors offered so far, plus the two motors that are “built in” to the Boost Hub. It would be reasonable to assume that the motors only differ by shape and power, but the truth is a bit more complicated. The table below highlights the technical capabilities of each motor.

Powered Up motors differ in several important ways:

• Physical Size – The smallest motor is 3×3×6 and the largest is 5×5×8.
• Motor Strength – Smaller motors have less power.
• Connections – The Boost, WeDo 2.0, and Train motors have traditional LEGO System ‘stud’ connections, whereas the other motors have LEGO Technic ‘pin’ connections.
• Motor Orientation – Some motors connect at the end, and others connect along the side.
• Speed Control – The “Simple” motors rotate more slowly as the batteries become depleted, whereas Speed Control motors try to adjust for the decrease in voltage.
• Rotation Sensor – Relative position is communicated back to the hub as the motor rotates.
• Absolute Position – The motor can rotate to a specific angle, and the current angle is communicated to the hub
• Zero Position Indicator – 0° direction is labeled on the motor.

Motors:

Part Number	Part Name (Year)	Size	Conn.	Orient.	Spd. Ctrl.	Rot. Sensor	Abs. Pos.	0° Ind.
21980	(WeDo 2.0) Simple Med. Motor (2016)	3×3×6	System	End	No	No	n/a	n/a

Powered Up Sensors & Accessories

You will need some sensors when designing and building programmable robots. The LEGO System-based sensors were introduced with WeDo 2.0 Core Set (2016 – now retired) and are also used in Boost (2017). The Technic sensors were introduced with the Spike Prime Set (2020).

Sensors:

	Part Number	Name (Year)	Size	Conn.
	20844	Motion Sensor (2016)	2×4	System
	20841	Tilt Sensor (2016)	2×4	System
	bb0891c01 / 26912	Color amp; Distance Sensor (2017)	2×4×2	System
	37308	Color Sensor (2020)	3×3×3	Technic
	37316	Distance Sensor (2020)	3×7×4	Technic
	37312	Force Sensor (2020)	3×3×5	Technic

In addition to sensors, you might want these accessories to complement your build.

Other Accessories:

	Part Number	Name (Year)	Size	Conn.	Additional Details
	47592	Powered Up 3×3 LED Matrix (2021)	3×3×3	Technic	3×3 Grid of Color LEDs, introduced in #45345 Spike Essential (2021).
	22168c01 / 22168	Powered Up Light (2018)	2x 2×1×2	System	Accessory designed for LEGO System Trains.
	bb0895c01 / 28739	Bluetooth Speed Remote (2018)	6×12×3	System + Technic	Standalone alternative to using your phone.

Sets containing Powered Up components

The following is not meant to be an exhaustive catalog of sets containing one or more of these Powered Up parts. Instead, I’ve focused on the most common sets where you can purchase each of the hubs highlighted in this guide.

Shopping Guide:

Part Number	Name (Year)	Sets
19071c01 / 19071	WeDo 2.0 Hub (2016)	#45300 WeDo 2.0 Core Set (2016) was the only set to contain this part. (It was the first hub to use the new Powered Up connection.)
bb0892c01 / 28738	(Small) Hub (2018)	#76112 App-Controlled Batmobile (2018) introduced this part in a small $100 set (which is now retired). #71044 Disney Train and Station (2019) and #21323 Grand Piano (2020) are current sets containing this component.
bb1165c01 / 22167	Technic Battery Box (2021)	This set was introduced in the ill-fated #42113 Bell-Boeing V-22 Osprey (It was recalled but a few copies were sold in retail stores.) For a while, you could buy the part directly from LEGO, but it does not appear to be available at this time.
bb0961c01 / 22127	Technic (Medium) Hub (2017)	The massive #42100 Liebherr R 9800 (2019) includes two of these Hubs. More economical options include #42109 App-Controlled Top Gear Rally Car (2020), or #42124 Off-Road Buggy (2021)
bb0894c01 / 26910	Move Hub (2017)	The older #17101 BOOST Creative Toolbox (2017) is still available. The newer Star Wars themed #75253 Droid Commander (2019) has already retired.
67351 + 66757	Small Intelligent Hub (2021)	The only way to get this is in #45345 Spike Essential (2021) which is designed for classroom use. I expect a consumer-facing product based on this hub will replace Boost in 2022.
45601 + 45610	Large Intelligent Hub (2020)	#51515 LEGO MINDSTORMS Robot Inventor (2021) is the consumer product containing the premium 6-port Intelligent Hub. #45678 LEGO Education SPIKE Prime (2020) was introduced a year earlier, and designed for classroom use.

Version History

In future updates to this article, I’m planning to add a compatibility column to these tables explaining which sensors/accessories are compatible with each hub and their associated software apps (including 3rd party apps and firmware).

• November 6, 2021 Added a table-of-contents and a shopping guide at the end.
• November 6, 2021 Added the three new parts introduced in the #45345 Spike Prime Essential set. (It’s an education product aimed at a younger audience than the Spike Prime set.) The new components are the 2-port Small Intelligent Hub (part 67351), Sm. Angular Motor (part 68488), and 3×3 LED Matrix (part 47592).
• November 5, 2021 Added the Technic Powered-up Battery Box to this list (part 22167) — It’s the only Powered Up hub that does not support Bluetooth. I also updated text about PyBricks to reflect that it is no longer in Beta.
• June 23, 2020 Fixed bugs, added year that each part was introduced, and fixed tables to render properly on small displays (such as phones).
• June 14, 2020 Updated page to reflect that most of these hubs will support autonomous mode using 3rd party firmware (provided by Pybricks). Also posted an updated Beta 2 of Powered Up Labels updated to include more consistent part names.
• June 12, 2020 Initial version of this page coinciding with announcement of new 51515 LEGO MINDSTORMS Robot Inventor set. Included Beta 1 of Powered Up Labels.
