Smallest 4 Character Dot Matrix LED Module

[lazy-b]

Guys: Here is the smallest Dot Matrix LED Modules, got it from RS Component, for USD 40.

Plan to use it on FUTABA 9CHP transmitter, might put inside the Memory Modules.....can be use to display the Telemetry data. such as Receiver Voltage, Rotor RPM, Engine Temperature.

Plan to use the Aux Channel 8 Knob Position into any Digital Number, that can be display on this tiny LED display.

here is the comparison of 20 years old 16 Segment Alpha-Numeric LED Modules and the newly acquired 5x7 Dot Matrix Alpha-Numeric Display....I've been dreaming of tiny LED a long long time ago.

I know its quite expensive for USD 40, I guess it would cost the same if you try to make your own from a discrete component.

Hi,Ellion

Here it is ... http://www.farnell.com/datasheets/46956.pdf

Price is a bit high ...indeed.

What about a small GLCD module ???

A little better datasheet here:

http://catalog.osram-os.com/media/_en/Graphics/00027300_0.pdf

I was using them on my altimeters (http://www.hexpertsystems.com/zlog) for a while, but on the latest version I switched to a 4-digit 7-segment LCD. Draws a lot less power, only 2 wires to the processor (i2c), and easily visible in bright sunlight.

Looks like the HCMS290x series from HP (now Agilent) is very slightly smaller
(about 2mm shorter in the long direction) but considerably less intelligent (No ascii;
you have to controll all the dots.)

That LCD display in the altimeter is really nice looking; where can you purchase
those?

It's a custom display, and they'll only sell it to you in volume, but I put a few on my site for do-it-yourselfers: http://store.hexsys.biz/cubecart/index.php?act=viewProd&productId=11
Datasheets are there too.

Guys: Thanks for all your Reply.

Yes, Able to download those DataSheet before ordering from RS Components.

Wow, thats a really small LCD display....I guess, I can just attach that small LCD display in a eye SUNGLASS's corner, and use it to READ a TELEMETRY Data.....with this you can Watch both Plane/Heli and Telemetry data simulatenuosly.

I was browsing an OLD Farnell Catalog 2000 last night and have found a better LED Dot-Matrix Display, I guess its same size as the 4 Character 5x7 Dot Matric SLR 2016, but this one is 10 Character 5x5 Dot-Matrix, and its Individual Dots Addressable.

Here is the picture, of that LED Modules, but I can not found the same item on its website, I guess, its obsolete now.

it seems 4 Character (1991) and 10 Character (1994) is made by the same Manufacturer.

[JimDrew]

The OSRAM parts are available and very easy to interface to a PIC or other micro. You can make the display horizontal or vertical as the display is dot addressable in columns and rows. There brightness levels and other neat features. They are a little spendy, but they do work well.

[lazy-b]

JimDrew, Yes, your Right.....in fact I can make it work without using any controller.

Guys, I almost burned up that USD 40 LED display Module.

this is the DataSheet Pin description
1 _____ 8
2 _____ 9
3 _____ 10
4 _____ 11
5 _____ 12
6 _____ 13
7 _____ 14

But when I wired it in the Breadboard, I assume its like this

1 _____ 14
2 _____ 13
3 _____ 12
4 _____ 11
5 _____ 10
6 _____ 9
7 _____ 8

I was thinking, that the Pin Description is arrange with the same position as the actual Modules (Which is very common on other IC's description)

I have mixed up from pin 8 to pin 14, when I connect 5 Volts supplies, there are no display, and when I touch the display modules, its heats-up, I immediately remove the power connection, and later I realize, I have missed wire the power supply.

Fortunately, Its still working, when I rewire it correctly.

Hmm, I have my OSRAM SLG2016 displays wired this way per the datasheet (shown below). Pin 14 (above pin 1) is ground.

[MX]

Oh, I see what you mean now. The Pin Function table lists the second row of pins physically backwards from where they should be.

[lazy-b]

Yes, Your Right.....I have mistakenly Connected the Ground to Pin 8 D5(Thinking the Description is exactly arrange with the Actual LED Modules), it should be connected to PIN 14.

Just curious, how much did you pay for your SLG 2016?

Guys, Hope you do not make the same mistake as I make....if its destroys the LED modules, it would be a very expensive lesson......I guess, I have ignore the PIN Numbering.

They have them at Arrow for about $17: http://www.arrownac.com. I got them closer to $14 in larger quantities. Of course, that's their North American site, so don't know what it would be to get them to the Philippines.

MX,

Thanks.....if I need volume will try to contact www.arrownac.com

The 10 Character LED Module SCDV 5542 is US$ 16.85 its even less expensive than the 4 Character LED Module SLR 2016 US$ 18.17 from www.arrownac.com

I usually order those hard to find stuff from RS component, there no minimum order and I pay in Pesos, and they deliver it to my door step.

Its so funny, lots of Electronics Items Made in the Philippines, but I can not find it here, like this Dallas DS1307 Real Time Clock is Made in Philippines, I have to order thru RS component, they have to ship it from Singapore.

same with the Intel Pentium IV processor, its made in Philippines, but our supplier have to source it from other country.......I guess, its really how those Distribution network work.

Have Downloaded the DataSheet of 10 Character LED Module SCDV5542 and found out its not a 10 Character, its also a 4 Character of 5x5 dot Matrix.....I guess, the SLR2016 still better, cause its Bigger character.
