Banggood

Qualche complicazione nel software di pilotaggio, con pazienza e la corretta libreria Arduino si riesce ad avere una corretta visualizzazione dei caratteri non invertiti sul display.

Very good price. The quality is there. Perfect for diy projects with an arduino. I recommend

The 8x8 by 4 display board took a little work to get software fonts to scroll the desired way a couple years ago. I make different craft signs for hobby demonstrations using this display board. I have shown where you can lift off some of the squares to get access to mount board to your project. It is very nice to let the chip do the refresh of LEDS and free up your microprocessor for other tasks and calculations. It seems to not draw as much current as when I use to directly light of dots from microprocessor

The order arrived in some 5 weeks. I already powered it up to see the basic function. All the red LEDs did light up, so I assume it works OK. I will test it in detail after the Xmas period with my Arduino. Now the price is even better than mine was - I paid US$3.56, while now it dropped to US$2.99 incl. shipment. The display/Matrix blocks are soldered in a non-porofessional manner, none of them is lined. I prepared photos to show the appearance - that is why I gave only 3 Stars for appearance and

the delivered part is not as the product photo and other parts i have got already. It has a gab of 1,5 mm between the elements an is not suitable for running magazine! But you can use the 8x8 LED for DIY.

Very good. Proper old-school red led matrix. Four modules on one board which could be cut apart if required, perhaps to make a 16x16 instead of 32x32. This daisy chained with the last one I bought and is working well. The picture shows it just pushed together at right angles with the last one for a quick test. Brightness set to zero is quite bright still, and possible to run marquee powered via an Arduino Nano. Be warned, at full brightness and all on (e.g. test mode), this willl likely draw too

Molto luminoso, buon display, peccato con le connessioni di colonna driver-display invertite, ma risolvibili via software correggendo i set delle librerie Arduino che crea qualche complicazione, ma il prezzo è molto buono.

Built quality seems good. Didn't check the working though. Has jumper cables, and a L shaped 5 terminal berg stick, which has to be soldered for further extension. Size is small, But worth for the price.

Jó minőségű termék,. Köszönöm!
