Tindie

I saw this recommended on Reddit as a way to prevent a Raspberry Pi from sending USB power to your printer. I was pleased to see it was a fellow Irish person who came up with the idea. On some printers an unshielded connection keeps the screen powered on even when the printer itself is powered off. The Blough-R eliminates that issue and saves people who are all thumbs (like me) from having to try and modify USB cables.

Excellent design with quality parts

For D1 Mini Breakout

I just received the D1 Mini breakout board and I am very impressed with the quality of the components and especially the extra attention that Brian took to add detailed silk screening to both sides the board. It was so clear that no instructions were necessary for assembly. Delivery to the US was quick and easy.

I will definitely be ordering more of these.

Works great!

For TS100 Flex-C-Friend

It works great. No problems whatsoever. Been using it with a MacBook Pro charger. I would recommend this to anyone who wants to use a USB-C charger as a power source to their TS100.

Just what I needed for my matrix project

Great documentation with plenty of examples. I had been powering my projects with a Arduino mega and pi over serial but this is so much smaller and more efficient! Its great that I can use the barrel connector for power, a big plus!

Chris | Oct. 4, 2020

Couldn't be better

Great product. Well documented and easy to build. Easier and neater than connecting the matrix panel with wires.

Matthias | Sept. 29, 2020

the shield dont work

Ich habe das shield nach der Anleitung zusammengebaut, und mit dem ESp 32 programmiert , aber nicht funktioniert keine LED leuchtet

Response from Brian Lough | Sept. 29, 2020

Hi Matthias

Sorry that you are having problems, but you could have contacted me to get support and I could have at least tried to help. The board will only support whatever displays work with the I2S matrix library though

Es tut mir leid, dass Sie Probleme haben, aber Sie hätten mich kontaktieren können, um Unterstützung zu erhalten, und ich hätte zumindest versuchen können, zu helfen. Die Karte unterstützt jedoch nur die Anzeigen, die mit der I2S Matrix library funktionieren (Google translate)

Mike | Sept. 29, 2020

excellent buy - thoroughly recommend

Very easy to assemble and did exactly what I needed! Solves the "pi powering the printer problem" at a stroke

Owen | Sept. 10, 2020

Great product from Brian, as usual!

I have numerous panels from Ali-Express and they all work fine with this board. The SPI library is so much faster than PXMatrix.

Response from Brian Lough | Sept. 29, 2020

Thanks Owen! Glad it worked out for you.

Excellent Product That Does Exactly What It Is Meant To Do!!

I am very happy with this item. I bought it in kit form and it was extremely simple to assemble and it worked exactly as advertised! This little unit solved the problem of the lcd screen staying on with my Creality CR20 printer when plugged in to the usb on my pc while the printer was tuned off. Very simple yet smart design.

Zhang | Sept. 4, 2020

Wonderful design, easy to use

The board arrived well packed, fast (international) shipping, and was easy to assemble. This shield was very well designed, and got my LED matrix display up and running in no time.

Nigel | Sept. 3, 2020

A fantastic shield

Another great product from Brian. It makes setting up the matrix panels a breeze. I just wish the programming would come as easy for me. A little tweak here and there and its up and running. Great documentation and help along with some great libraries that he and fellow programmers are involved with.

Response from Brian Lough | Sept. 29, 2020

Thanks Nigel. I'm working on some projects for the i2s matrix I think you'll really like, so stay tuned!

Patrick | Aug. 26, 2020

Makes the i2s connection a breeze

When I saw the i2s dma library in a test video, I just knew it was the way to go. I was originally going to get his other board but he had just released this one and I'm glad I got this one instead. The shipping from Ireland to Florida only took a week or two. The instructions were very clear. Make sure you use a lot of solder on the screw terminal. The only change I would make would be to use a male IDC (2x8) connector (like the one on the led panel) so I could use the included ribbon cable that comes with every led panel. It creates a more secure connection. My led panel has a frame on the back that doesn't allow Brian's board to seat properly, so I use a female to male ribbon cable.

Response from Brian Lough | Sept. 29, 2020

Thanks Patrick. Thanks for the feedback around the male IDC connector, I will hopefully add that as an add-on in the future. One of the problems with these matrix panels is they come in all flavors and sizes! The board fits all mine ok, but I understand there are ones that it doesn't.

Dj | Aug. 18, 2020

Great little board

Really crunches down the size of device needed to drive a HUB75 LED array well, Up and running quickly, a little too quickly for me as I beat the docs going up, but lots of help on the Discord server and I have much glowyness to hand.

Response from Brian Lough | Sept. 29, 2020

Thanks Dj! Apologies about the delay in the docs going up! Glad your up and running.

Donald | Aug. 17, 2020

Fantastic product shipped promptly

Like many, I was frustrated at my 3D printers still receiving power from my Raspberry Pi's even when turned off. So when I heard of the Power BLough-R, I ordered 5 of them immediately. (2 for my printers, and 3 for friends and extras in case I screw up in assembling one.) The kits arrived SUPER FAST (Got to me in the States in less than a week, which quite frankly amazed me) and the soldering was pretty easy, even for a greenhorn like me. Works perfectly, and paired with the 3D printed case, they look totally professional, MUCH nicer than the dodgy hand-hacked data-only USB cables I was using, which I can now happily retire.

Top stuff

For TinyPICO Matrix Shield

Really useful board and works flawlessly. One thing to note, which you would get hints of if you watch the seller's youtube channel or look at some other listings; if you want to use this with a Pixel Purse display, you will need to solder an additional 8x2 header to the display, because the PxMatrix library uses both the input and output ports.

Gordon | July 18, 2020

Really useful little device, shipped quickly

Great device, " does what it says on the tin". Shipped and delivered quickly. No documentation or communication from Brian was necessary with this order. Will happily buy more products from this seller in the future.

Hamish | May 29, 2020

excellent gizmo

For Feather Huzzah 32 Debug Shield

Perfect if you want an easy way to debug an esp32 feather!
just solder on the headers and off you go :)

Joel | May 23, 2020

Great product

Works exactly as advertised and perfect for use on my 3D printer with Octoprint to prevent it from staying on. Small gripe is that as an absolute noob at soldering some instructions would have been nice, but otherwise A++ product.

Hans | April 26, 2020

Great product

Good kit, easy to assemble, all parts are there .

Excellent product, easy to assemble

The shield is well designed and easy to assemble (solder), though you probably gonna need two different soldering irons, one for smaller pitch components (headers) and one for the bigger parts (power connectors). Unfortunately, I've not been able to test the shield yet because my P3 64x64 matrix (ordered at Amazon from DFRobot) was a bit off, i.e. it did not respond correctly to PxMatrix library which expects a /32 scan rate for these displays. Apparently the DFRobot display uses a /16 scan rate and therefore uses its own libraries. I've returned the display and I've ordered one on Ali.

D1 Mini matrix Shield for ESP8266

I was very p;leased with this board, it enabled me to get a P3 matrix display running in minutes, little more than plug-and-play. Brian has put a lot of thought into the design and it shows with everything about the board.

I would buy again from Brain based on the quality and service received.

Peter | April 9, 2020

Recommend this item

For D1 Mini Breadboard Buddy

Really useful adaptor, well designed and it works .....................................................

Chris | April 9, 2020

Excellent product

For BLough Alarm Clock - Shield for Wemos D1 Mini

I got the RGB matrix working with dupont cables, but it was a mess. So I decided to neaten things up and order the ESP32 shield, and am glad I did. Very neat and now I can hang my display up on the wall, plus don't need to power the ESP seperately which is a bonus. Plus Brians youtube videos are useful. Thanks!

Peter | April 9, 2020

Easy to Build

Worked first time, but had to replace the lost (on the carpet): diode.........................................

Wim | April 2, 2020

Just a great little board. Must have for LED Matrix panels

When wiring up my 64x32 panel, came across this nifty little board and ordered it right away. Ships fast, has plenty of online documentation and above all prevents a rats nest of wires coming out of the panel.

Nigel | March 24, 2020

A fantastic shield

For TinyPICO Matrix Shield

This shield along with a tiny pico made setting up my matrix display a doddle. Code loaded board powered up and after a few seconds the time appeared. The board was easy to assemble with the use of the informative guide on Brians page. Very impressed

Spencer | March 11, 2020

Great kit. Gets the job done!

Excellent kit. It's top quality and was delivered really quickly. Documentation is great and the example code got me up and running really quickly. I used it for the Pixel Purse 16*32 screens. It works great with 2 screens daisy chained, but with 3 there is some colour tearing (Not a fault of this kit, but a limitation on the screens I was using).

Power BLough-R: Great for OctoPi 3D Printers

I bought a handful of Power BLough-R kits to polish up on soldering and upgrade from using kapton tape on my USB cables for my 3D printers. The packages came relatively quick for international mail. I wish they were more streamlined, but that would make soldering more difficult... I highly recommend these!

Andrew | Feb. 6, 2020

Fab PCB

Perfect, nicely designed PCB that saves ages if you had to wire it up with jumper leads, worked perfectly with a cheap display from Amazon and a even cheaper ESP32 from ebay, well done Brian..

David | Feb. 6, 2020

All in all generally good, delivery,

Good delivery time, five days 2nd class mainland UK,, Product good also works like I wanted it too, have to buy a few more(new projects 😉)

Davide | Jan. 30, 2020

Great kit, quick to assemble, works perfectly.

I have a 64x64 3mm pitch matrix display from China and this shield works without issues with it. Assembly / soldering was also very easy and quick. Using the display without shield would mean a mess of wires but this is a very neat and tidy solution with pretty small footprint. The kit actually comes with two power connectors, I suppose for if you want to use two displays.

Nigel | Jan. 29, 2020

Fantastic bit of kit

Have watched a lot of Brian's videos on youtube and this shield saves the spaghetti of wiring when working with matrix panels. The online institutions and assembly were easy to follow. The board is well made and thought out so will have fun with the programming. I have ordered another along with one for the tiny pico

Gunther | Jan. 29, 2020

Does exactly what it says on the tin.
