I have just tested this ready made active adapter board on a Pi3: http://www.electrodragon.com/product/rgb-matrix-panel-drive-board-raspberry-pi/ It works. I'm using it with 18 64x32 P3 panels 2017-10-07 10 54 20 2017-10-07 10 53 18 2017-10-07 10 53 54

Ohh this is nice! Can I ask you where they shipped it to? I.e. what country do you live in? Br Claes

marcobrianza commented 6 years ago

Italy

maddogs commented 6 years ago

I bought a couple too, shipped to the UK within a week. All Worked great.

ghost commented 6 years ago

Thanx for all the info! I have just order one myself, ship to Sweden

soyxan commented 6 years ago

My board is on the way. But reading the product info page I have seen extra features, anyone can explain what can we use them for:

Extra on board RTC DS1307 via IIC interface, can not be used on same time with P3 port, select by switch.
Extra on board AT24C256 EEPROM, 256K memory on alternative IIC 25 and 26 pins. Raspberry PI 3 can NOT support alternative IIC interface, so can only be used Raspberry Pi 2.

Thanks!

maddogs commented 6 years ago

The RTC DS1307 is Real Time Clock. I have no use or it as my pi updates Time Date via internet. May be handy if the Pi is going to be stand alone and powered off regularly.

Not sure what the EEPROM is for.

depili commented 6 years ago

The extra stuff are of quite limited use. The RTC chip used is quite inaccurate and it will drift. EEPROM is a form of solid state storage commonly used in microcontrollers and generally inferior than using the sd-card on the pi.

Can you tell us what kind of panels you are using with this board? Looks great!

maddogs commented 6 years ago

I'm using what I'd call the standard 64x32 panels from Ali-express (two 32x32 internally chained) they don't need any transformer written.

this is the link to the panels I have used https://it.aliexpress.com/item/p3-full-color-led-module-high-clear-high-resolution-black-leds-high-contrast-ratio-smd-0606/977188631.html?spm=a2g0s.13010208.99999999.289.ZyoF2k

Quanto hai speso per la dogana italiana? Varia in base al quantitativo? Ciao, Alberto

marcobrianza commented 6 years ago

I used a shipping method with prepaid customs duties

alverman commented 6 years ago

? Me lo spieghi in italiano :)

marcobrianza commented 6 years ago

alverman commented 6 years ago

Grazie 👍

Hello, I bought this card a few months ago but I can't see anything on my LED Panel, 320x160, there is a page with which to follow all the steps for installation from a raspberry pi zero w. ? I am a little newbie in this world. Thanks
