that connects a microprocessor to an 8-digit digital 7-segment LED display. It can also
be connected to a bar graph display or 64 separate LEDs.
2. It includes an on-chip B-type BCD encoder, multi-channel scan loop, segment word
driver, and an 8*8 static RAM to store each data. Only
one external register is used to set the segment current of each LED.
3. A convenient four-wire serial interface can be connected to all common
microprocessors. Each data can be addressed without any need to overwrite
all displays when updating. The main chip also allows the user to choose
whether to encode or not encode each data.
4. The entire device includes a 150μA low-power shutdown mode, analog and digital
brightness control, a scan limit register that allows the user to display 1-8 bits of data,
and a detection mode that allows all LEDs to illuminate.
5. Only need 3 IO ports to drive 1 dot matrix! No flicker when the dot matrix is ??displayed! Support cascading!
6. Module with input and output interface, support multiple modules cascade.
7. With 64 fixing screw holes, 3mm aperture, a single module can drive an 8*8 common cathode array.
Wiring instructions:
1. The left side of the module is the input port, and the right side is the output port.
2. When controlling a single module, you only need to connect the input port to the CPU.
3. When multiple modules are cascaded, the input of the first module is connected to the CPU, the output
is connected to the input of the second module, the output of the second module is connected to the input
of the third module, and so on.
Take 51 MCU as an example:
VCC → 5V
GND → GND
DIN → P2.2
CS → P2.1
CLK → P2.0
Packing includes::
1 x dot matrix module
5 x DuPont line

Display molto luminoso, e di facile utilizzo con l’apposita libreria, ottimo per progetti sperimentali è perché no, anche per auto costruirsi un’ orologio…un consiglio, nel caso ci siano problemi di funzionamento provare a ruotare di 180 gradi le matrici led, mi è capitato che l’accensione della matrice era random e non c’era verso di sistemarla poi ho scoperto l’errore di assemblaggio.

Matrice led (blu) usata per costruire un orologio digitale con ESP8266. La luminosità è molto alta ed è perfettamente visibile anche con la luce del sole. Ottimo acquisto.

I recently got the Youmile 8x32 Dot Matrix Single Light LED Display Module for a project I'm working on, and I'm really pleased with the results!Firstly, this thing is solidly built. It feels durable and like it can handle a lot, so I'm not concerned about it breaking. The bright lights it emits are attention-grabbing and give my project a cool look. The display size is just right at 8x32 dots, providing enough space to showcase what I want.Setting it up was a breeze. I appreciate that it works seamlessly with different platforms like Arduino, Raspberry Pi, and others. Plus, connecting it to different control systems isn't overly complicated, which is great for someone like me who's not new to this.In terms of performance, this LED display exceeded my expectations. The lights are bright and consistent, and everything shows up clearly. Whether I'm working on a scrolling message or a simple animation, this Youmile module handles it well.I also like that they made it user-friendly. The instructions are clear, and everything is labeled nicely, making setup straightforward.If you're in the market for a reliable LED display module for your projects, I highly recommend the Youmile 8x32 Dot Matrix Single Light one. It's durable, easy to use, and adds a cool visual element to whatever you're working on.

Worked as expected apart from the wrong colour. I sent it back but got a replacement
