Pico Bricks Review: Great STEM Learning Platform
Studying to code, particularly with electronics, may be fraught with issues. Are your connections right, are they designed to work together with your motherboard, and is your code right? All these issues may be deadly to a scholar’s progress. Studying to fail and take a look at once more is a vital talent, nevertheless it requires a point of success. Piko Bricks It goals to make it straightforward for college kids to write down code and construct digital circuits utilizing our favourite microcontroller. Raspberry Pi Pico.
There are three kits. It is a $59 base package that gives the motherboard and some further parts. The IOTExpert Package prices $84 and with it you get a wise greenhouse, servo controls and extra parts to work with sensors. The highest-of-the-line package is the $117 Zero to Hero package, which bundles the IOT package with servo-controlled robotics, a robotic chassis, RFID reader, and lots of different sensors.
Pico Bricks is marketed to trainers, however can it train this previous canine just a few new tips? To seek out out about this and be taught extra concerning the package, I lined up the package and made some tasks from the e book. Observe that my overview package is a mixture of IoT and Zero to Hero package, so I am focusing extra on the bottom board than the extras included.

Putting in Pico Bricks
Pico Brick’s visible aesthetic is evident, easy-to-understand electronics. There are not any flashy design flares, simply easy labels figuring out parts. The PCB is positioned on a plastic base. We initially thought it was 3D printing, nevertheless it seems to be prefer it was injection molded. The PCB may be faraway from the bottom, watch out as it’s a tight struggle. The bottom is there to stop unintended quick circuits. An area the place tasks may be soldered, the protocol is a pleasant contact for when college students are able to construct their very own circuits.
The great thing about Pico Bricks is that there’s little or no setup to do. {Hardware} comes pre-connected; All we’ve to do is set up the related software program. On-line guides and e-book present the mandatory info to do that. Conversely, probably the most tough to arrange is the only technique to code. MicroBlocks is an open supply, block-based editor for microcontrollers and requires customized firmware to be put in.
As soon as the firmware is loaded, the browser-based editor can discuss to Pico and run the code. Utilizing MicroPython requires tried-and-true methods to obtain the newest firmware and drop the UF2 file onto the drive. My first try was unsuccessful as I forgot to unplug the Pico whereas making an attempt the Arduino setup, maintain the BOOTSEL and plug it again in. Should you do not do that, the Arduino IDE won’t be able to load the code.
Utilizing Pico Bricks

Pico Bricks has considered customers of all ranges, and that is one thing I like. All parts akin to a part of the framework or extras in my package may be managed utilizing MicroBlocks, MicroPython and Arduino. They may also be managed utilizing C/C++ and CircuitPython or certainly one of many different Pico supporting languages.
Pico Bricks gives a better {hardware} interface. I’ve caught to the beneficial languages ​​for my testing and may report that the majority of them work as anticipated. I adopted just a few tasks from the e book and located the MicroBlocks tutorials to be wonderful and straightforward to comply with aside from one.
The greenhouse coaching makes use of an ESP8266 (ESP-01) module for Wi-Fi connectivity. The guide confirmed all the mandatory blocks to attach, however did not inform me get them. Additionally, some by no means mentioned create the features wanted to ship serial information between Pico and ESP8266. The MicroPython and Arduino tasks had the code, however didn’t clarify import modules/libraries to make use of some parts. Fortunately I understand how to do that, however somebody migrating from block to textual content code tasks will run into an enormous drawback. Proper now the {hardware} is stable, however the accompanying e book is a blended bag.

{Hardware} is the star of the present. I like this format as I’m an enormous fan of Stemma QT and Grove connectors. The truth that the parts are scattered across the Raspberry Pi Pico jogs my memory of Seeed’s Grove Newbie Arduino Package. The $4 Raspberry Pi Pico is related by way of a sequence of header connectors with further connections for conventional parts. Utilizing a hood means we will substitute the Pico with the Raspberry Pi Pico W and benefit from Wi-Fi and Bluetooth.
There are a variety of white connectors surrounding the Pico. These connectors work with embedded parts; they’re truly labeled in line with their location. There isn’t a want to make use of the equipped cables. Embedded parts are electrically related to the Pico by way of traces on the PCB. This implies we will simply begin constructing tasks utilizing parts.
Connectors come on their very own when used with exterior parts, and my overview package, which is a mixture of IoT and Zero to Hero kits, had many extra parts to attach. Embedded parts may be cracked and used externally, helpful for embedding in a robotic or information acquisition mission. The $59 base package gives the identical performance as my costlier overview package, however you do not get any of the additional parts wanted for any e book mission.
Can I exploit my in depth assortment of Grove parts with Pico Bricks? The quick reply is sure, however there’s a caveat. I related a Grove relay to the LED connector utilizing a Grove cable. After a couple of minutes, I had a loop that turned the relay on and off. The connection between the Grove cable and the connector on the Pico Bricks was good, albeit a bit flimsy. I hit a barrier whereas making an attempt to make use of a Pico Bricks cable with the Grove element; it simply did not match. It seems to be just like the Pico Bricks connector has a distinct form.
because of this the tip can’t be pressured into place with out forcing the plastic. An important tip, when you have Grove parts, use the Grove tip. Should you plan to buy Grove parts, additionally buy some leads.
The element choices will not be authentic, Cytron’s Maker Pi Pico introduced the ESP-01 module to this format and Seeed’s Arduino-based Grove Starter Package launched many of the parts. What Pico Bricks presents is a relay and a motor driver. The relay is an ordinary module rated as much as 250VAC. We don’t suggest utilizing 250VAC with this element. Excessive voltages may be deadly and all acceptable security practices should be adopted. One of the best security follow is to not mess with it, imagine me I’ve had just a few electrical shocks, they’re no enjoyable!
The motor driver is an L9110S, a reliable motor controller for primary robotics. I examined this with a motorized pump (included within the overview package) and it labored with minimal code.
Who Are Pico Bricks For?
Pico Bricks has a transparent give attention to training. Ease of use and the e-book are clear indicators of this. The all-in-one design is appropriate for educators who need to run their classroom rapidly and with minimal fuss. Embedded parts imply no messy cables to attach and tidy up on the finish of the session.
In conclusion
At $59, the essential package is not low cost. It has some nice options, however must decrease the worth of the essential package to make it extra interesting to dwelling customers. Educators, one of the best factor you are able to do is the Zero to Hero package.
The additional spend brings a compiled set of tracks, all assured to work with Pico Bricks, together with an accompanying e-book that may be helpful in classes. For producers normally, that is extra of a curiosity than a primary buy. You probably have children, Pico Bricks is a great tool to introduce them to coding and electronics with out having to dedicate a drawer to parts.
Makers, if you would like a easy connection system for Raspberry Pi Pico electronics, get your self a $4 Seeed Grove Protect. Chances are you’ll not get all of the parts, however you should purchase precisely what you want for little or no expense. Though I am not the specified demographic, I beloved my time with Pico Bricks. A enjoyable package value exploring.
