Micro:Bit Breakout Boards...

[Melissa De Sole]

I'm looking for breakout board suggestions to pair with the micro:bit for an 8th grade project. Features that would be helpful:

• beginner-friendly layout (I like the color-coding on some ElecFreaks boards)
• easily plugs in to a power source that can run two or three 9g Micro Servo Motors, plus possibly LEDs
• compatible power sources are easily replaced/recharged

I really like the layouts of the ElecFreaks Wukong, sensor:bit, and octopus:bit but am struggling to find an easy power source for them. This year, we've been using the bit:explorer, which works alright, but the power switch falls off easily and its layout is not intuitive for beginners.

Any suggestions would be very welcome!
Thanks,

Mel

Hi Mel,

I was on a similar mission last year and tested a variety of breakout boards. I ended up going with the Kittenbot Robotbits. They use a rechargeable 18650 battery that can easily be recharged through the breakout boards using USB.

They are a bit complex, but it allows for a wide range of creative projects and can easily power multiple motors/servos. 

There are 8 IO pins, so you can attach basically anything including LEDs, but the board includes three RGB LEDs that the kids really like. There is also a MakeCode extension that makes programming fairly intuitive. 

Kittenbot has some other boards, which all seemed robust to me, unlike ElecFreaks. I bought a few things from them, but they all seemed to break very easily. 

Thanks,

Jeremy

Hi Mel,

I know that you are looking for breakout board suggestions.  I was just going to share what I use because I have found it easier overall for 8^th graders of a wide variety of skills. I use the Elecfreaks Nezha and Planet X devices.  The Nezha can power up to 4 servos and 4 motors plus and additional 7 inputs and sensors.  I find the plug and play aspects so much easier to get kids up and running. Easy to attach.  Easy color coding.  Clear MakeCode extensions.

My favorite breakout boards for micro:bit are the Keyestudio Motor Driver Breakout Board and the Keyestudio Sensor Breakout Board, both $10  on Amazon.

They can be powered from a USB cable coming from a laptop or outlet, have outputs for servos, have access to all the micro:bit pins with jumper wires, and best of all, they have 5V in addition to 3V.  We use the sensor board for our pinball games to read analog and digital switches, and control servos lights, and speakers. Currently using the motor driver to drive DC hobby motors, read in 3 analog sensors, and control the HC-SR04 distance sensor.

If you're looking for a beginner-friendly board and you are mainly concerned with servos, LEDs, and easy power, the Hummingbird Robotics Kit by Birdbrain Technologies is about as approachable as they come. 

**One of the tricky bits on many breakout boards tends to be dealing with LEDs. Unless the board has dedicated ports for LEDs, you'll need to involve a resistor which can be fussy, whether included by the student or pre-wired in. I love that the Hummingboard board has dedicated LED ports that output exactly the current that the LED needs without any fuss**

The boards support up to 4 servos (either position or rotation servos), 3 single color LEDs, 2 Tri color LEDs, 3 sensors, has a built-in piezo, and has an extension port that supports I2C. It is powered via a 4x AA battery pack (included), or an optional power adapter or rechargeable power bank.  It is sold as a kit, with all the components included. You can also buy boards and other items a la carte from the parts section of their store.

If your projects stay within those boundaries, this is a solid product. But if you want your students to venture beyond these walls, many of the other boards mentioned earlier may be a better fit. I have found it super-easy to get entire middle school classes off the ground quickly and working independently with the Hummingbird boards. For my more advanced students who want a wide playground, I use a variety of other boards that are far less beginner-friendly.

I was JUST looking at all your pinball stuff for the first time yesterday!!! What a coincidence.  

I have been thinking about making modular pinball machines with/for young students but instead of using pegboard I was thinking about using sheet metal and magnets for all the bumpers, ramps, spinners, etc.  

I love that you gave access to all the files.  I am considering doing a unit with 8^th graders where they work in teams to design the games for younger kids.  One student becomes an expert with the laser cutter, one with the 3D printer and one with the coding of the MicroBit.  

I’d love to pick your brain if you had the time.  

Rob.

I like the Elecfreaks Nezha Pro and easy-to-attach servos and accessories. A cheaper Elecfreaks option is the micro:bit "Ring:bit" bricks pack, but it uses 3 AAA batteries instead of rechargeable.

I adore teaching with the Scratch-style liveness of MicroBlocks. Another extremely powerful learning capability is that when running MicroBlocks in the Chrome browser, you can program the micro:bit live while it is untethered. You simply use the "connect (BLE)" option, and select your board's unique 3-letter BLE ID. I use that method instead of a USB cable to code and test all servo or robotic car commands because a USB cable interferes with the natural movement. The "Kits and Boards" folder contains the Nezha2 and Nezha Pro libraries. The blocks are super easy to understand. 

Another options for MicroBlocks is using the CoCube app. The CoCube app is a fork of MicroBlocks that can run on Android and iOS devices, such as iPads and tablets. It supports the MicroBlocks live method of programming any board, not just the CoCube. After opening the app, you again use "connect (BLE)" instead of a USB cable. Just be sure to pre-flash the MicroBlocks firmware on the micro:bit or other hardware such as the CoCube first -- you need that firmware so the CoCube app can see and connect to the board over BLE. By the way, the CoCube is a super cool educational robot (I personally know and admire the inventor, Shuai Liang; great engineer still finishing his PhD). And talk about easy to connect accessories -- they attach with a magnetic connector in a snap.

To learn more about the value of "tinkerability" using MicroBlocks, check out this keynote by the founder and lead developer (John Maloney), who led Scratch for the first 11 years as well.
