Also on-board are four test buttons that allow you to get your motors moving and check they work without any programming.<\/li>\n<li>4 x servo motor outputs &#8211; for fine motor control.<\/li>\n<li>1 x piezo buzzer &#8211; so you can play beeps and other sounds (this can be disabled completely by an on-board switch).<\/li>\n<li>2 x Neopixel-style user-controllable RGB LEDs.<\/li>\n<li>A collection of low-power LEDs in-line with all the input\/output ports so that you know what has been activated (and who doesn&#8217;t like blinkies?)<\/li>\n<li>2 x user-defined buttons &#8211; perhaps you can use these to put your robot into different modes&#8230;?<\/li>\n<li>A Run\/reset button and a Boot button.<\/li>\n<\/ul>\n<p>If you want to <a href=\"https:\/\/docs.google.com\/document\/d\/1DJASwxgbattM37V4AIlJVR4pxukq0up25LppA8-z_AY\/edit\" target=\"_blank\" rel=\"noopener\">take a look at the Datasheet, you can find it here<\/a>.<\/p>\n<h3>Let&#8217;s talk about power<\/h3>\n<p>In terms of powering the board and the motors, you have\u00a0<strong>three<\/strong> options:<\/p>\n<ol>\n<li>Supply power through the microUSB socket (very handy when you&#8217;re testing things out\u00a0<strong>and<\/strong> programming at the same time).<\/li>\n<li>Supply power via a single-cell 3.7V LiPo battery. (The microUSB input will charge your LiPo as well, with overcharge and undercharge protection built-in).<\/li>\n<li>Supply power via the screw terminals between 3.6V and 6V (the max is equivalent to 4 x non-rechargeable AA batteries, but you can, of course, use rechargeable ones instead).<\/li>\n<\/ol>\n<p>All the power is handily isolated by an on-board power switch so if you just need to shut the thing off, one click and you&#8217;re done.<\/p>\n<h2>Having a play<\/h2>\n<p>I hooked up two 6V DC motors to the board using the screw terminals (thanks again for the screwdriver!) then used the test buttons to make them run. Excitingly, it &#8220;just worked&#8221;. I then used the pre-loaded demo script to automatically &#8220;turn the robot on the spot&#8221; (which it would have done had I not elevated the wheels before I hit the button!). You can see a short demo video of it working below:<\/p>\n<p>&nbsp;<\/p>\n<p><iframe loading=\"lazy\" title=\"Maker Pi RP2040 motor test\" width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/xoU2A2y_FCo?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>I also hooked up a servo and used the demo script to turn it back and forth. These are small steps, but vital ones, as it proves that everything works and you&#8217;re ready to embark on your future exploits.<\/p>\n<p>Speaking of which, Cytron have provided <a href=\"https:\/\/github.com\/CytronTechnologies\/MAKER-PI-RP2040\" target=\"_blank\" rel=\"noopener\">a GitHub repository to help you, full of demo scripts for both CircuitPython (which is pre-installed) and MicroPython<\/a>.<\/p>\n<p>You can <a href=\"https:\/\/github.com\/CytronTechnologies\/MAKER-PI-RP2040\/blob\/main\/Examples\/CircuitPython\/Out-of-the-box%20Demo%20Code\/code.py\" target=\"_blank\" rel=\"noopener\">see the code for the pre-loaded demo here<\/a>. As you can see, for DC motors you simply use the pwmio library to define the motors and then trigger them. For servos, they are using Adafruit&#8217;s adafruit_motor\/servo library. Normally, I&#8217;d criticise them for not building their own library, except a) why re-invent the wheel? and b) they&#8217;re using CircuitPython for this anyway, and Adafruit invented that!<\/p>\n<h2>What did I think?<\/h2>\n<p>I think this is an <strong>excellent board for beginners<\/strong>. With the ability to hook motors up, provide power and then just click a button to test the motors out, you get the instant gratification that both kids and adults love. Programming the RP2040 is easy (especially using CircuitPython) and if you added on, say, a <a href=\"https:\/\/thepihut.com\/collections\/cytron\/products\/maker-line-simplifying-line-sensor\" target=\"_blank\" rel=\"noopener\">Cytron line following sensor<\/a> (which might be a bit &#8220;cable-y&#8221; using the Grove sockets, admittedly), it&#8217;s clear to see how you could create a line following robot, as an example, quite simply.<\/p>\n<p>The only caveat I really have with the board is that, because it&#8217;s all very centred around the 7 Grove sockets, there&#8217;s no direct access to the GPIO ports. Sometimes, you just want to hook something up without needing a special cable to do it. Now, they obviously provide 4 of these &#8220;special cables&#8221; to enable you to do that, which is very handy, but having (even unpopulated) headers for the pins might&#8217;ve made things even more flexible. Of course, the board is 85mm x 60mm (approx), and that small size is very attractive. There are always trade-offs, though, in any product, and it doesn&#8217;t stop me recommending it, it&#8217;s just something to be aware of.<\/p>\n<p>The three power options are very flexible, and it&#8217;s good to see a LiPo port on there, even if beginners probably shouldn&#8217;t use them to start with. Adding the charging circuitry in, though? Very good move from Cytron, there.<\/p>\n<p>I do keep mentioning that it is for beginners. Well, at 1A per channel, it&#8217;s not going to blow anyone away in terms of sheer power. Having said that, as a trade-off, you can run 6 motors independently, so one shouldn&#8217;t complain! They have a lovely range of other motor controller boards able to provide more grunt, so there is a clear path to change your method later when you get more advanced.<\/p>\n<p>Overall, it&#8217;s a solid 9\/10, I think, and a great use of the RP2040 chip.<\/p>\n<p><strong>Another winner from Cytron &#8211; highly recommended<\/strong>.<\/p>\n<p>For another take on the same board, I suggest having <a href=\"https:\/\/www.tomshardware.com\/uk\/reviews\/cytron-maker-pi-rp2040-review\" target=\"_blank\" rel=\"noopener\">a look at Les Pounder&#8217;s review over at Tom&#8217;s Hardware<\/a>.<\/p>\n<h2>Where can I get it?<\/h2>\n<p>In Malaysia and surrounding countries, <a href=\"https:\/\/www.cytron.io\/p-maker-pi-rp2040-simplifying-robotics-with-raspberry-pi-rp2040\" target=\"_blank\" rel=\"noopener\">go directly to the Cytron website<\/a> where the board is available for $9.90.<\/p>\n<p>In the UK, I recommend <a href=\"https:\/\/thepihut.com\/products\/maker-pi-rp2040\" target=\"_blank\" rel=\"noopener\">The Pi Hut<\/a> where it is listed at \u00a39, but I notice they are currently out of stock.
