It is in the process of being released to the library manager but at the time of writing this Instructable the library is only available through Github. The first one we need to install is the PXMatrix Library by 2Dom. To use the display we are also going to need to install some libraries. If videos are not really your thing, check out lesson 2 of Becky's awesome IoT Class, it goes over everything you need as well.īefore you move to the next section you should be able to upload a simple sketch to your ESP8266 (such as the blink example mentioned in both the video and Becky's lesson) Installing libraries It's only 5 minutes long and goes through everything you need to setup. If you have never used the ESP8266 or Arduino before, we will need to a little bit of software setup. There are a couple of things you will need to have setup before you can start using these displays. 10pcs 2.1mm Adapters*, This contains a set of both sockets and plugs, but they are pretty cheap and useful so worth picking them up. An ESP8266 development board, I recommend the Wemos D1 Mini Clone* as they are very small and cheap ($3 delivered).I much prefer the laptop style as the other requires you to connect mains voltage wires to it, and working with mains voltage is something I like to avoid as often as possible! Here is a link to the same type of one I used (5v 8 amp laptop style) .uk* * (This seems to come with the adapter for connecting to the power cables) Aliexpress* Other Components One is similar to a laptop and has a 2.1mm jack as its output and there other is more similar to type that comes with 3d printers. There are two different types of power supplies that you can get: The first thing we'll need is a pretty large 5v power supply, Adafruit suggest that 64x32 matrix can require up the 8 Amps! This is worst case scenario (all LEDs set to white) so in reality you probably won't need one that big, but there is no harm in having the head room. Power connecting cable - This cable connects to the power connection of the display and exposes two terminals for you to power it with (more about this in the next step).4 screw mounts - these screw into the back of the display and have magnets on the bottom of them so you could attach this display to something metal.A ribbon cable - this can be used to chain displays together (which is supported by the library we will be using, but I only have one display so I won't be able to advise on it).If you get the board all you need to get is an Wemos D1 mini style ESP8266 and a Power Supply (both listed below)Īlong with the actual display you will also get the following: If you are based in the UK, Colin Hickey also sells them on his store If you are interested in buying one, I sell them on my tindie store. 200 mA n° of LEDs: 128 LED pitch: 4 mm communication: I☬ chipset: AIP1640 oscillation frequency: 450 kHz working temperature: -40 to 80 ☌ panel weight: 12 g dimensions: 72 x 32 x 8 mm (2.83 x 1.16 x 0.EDIT: Since making this guide, I have made a PCB that makes using these displays really easy! It makes use of the wires than come with the displays for easier connections. Specifications: Specifications operating voltage: 3.3 to 5 VDC operating current: max.This product is a replacement of: VMA451 Specifications Light up your projects with this bright board! You can easily connect this board with the included HW-2.54 4 pin cable (GND, VCC, SDA & SCL) to your development board or breadboard. This module is an 8×16 LED matrix panel board that comes with a total of 128 blue LEDs and the AIP1640 chip mounted on the back so you can communicate via the I☬ protocol.
