New 64x32 and 64x16 Bi-Color LED display PCBs with built in TM4953 MOSFETs, 74H

T&E Engineer

Has anyone looked at these new LED display boards from Sure Electronics (China)?

http://www.sureelectronics.net/goods.php?id=146·(64x16)

Sure Electronics sells very cheap 8x8 LED·modules on EBAY where I have bought many of them for my SX and BS2 projects.

I am so happy to see a company that is selling the complete display PCB.·You can interface to them with a micro-controller like an SX chip or BS2 perhaps.

The boards are still in development for a couple more weeks or so before they will release the cost of them.

They do have some smaller single color boards (24x16) that can be cascaded (up to 4) for $23 each. However, these boards use more of an SPI interface and have PWM which is ok - just a bit different from there larger 64x16 and 64x32 displays.

Comments are welcome.

I have a couple of the 24x16 boards I picked up on e-bay for $10 and $15 (two separate purchases). They're pretty nice. Wish they were bi-color, though. The 24x16 boards are still available on e-bay, although they don't seem to be listed as often as they used to be.

Good news and bad news.

Prices for these display boards are out being $19 for a 64x16 display board and $34 for a 64x32 display board.

Bad news - shipping from Hong Kong is $20 - $27 - ouch (but that's the price you pay). AND you have to a PAYPAL account too.

I will probably pick up one of these boards and develop something with SX/B in the next couple of months.

I just bought 2 of the big boards (64x32) but the shipping also went up to a total cost with shipping just under $100.

According to the datasheet, the 64x32 panel displaying frequency is 70 frames per second with screen refreshing to be done every frame. It also states the scan time of one row is not less than 1/(80*16s).

I hope a SX-28 or 52 proto board·can meet these timing specs.

too bad I can't use paypal. theres some interesting things there

T&E Engineer

Agh!!

The prices just went up·$6 for the smaller board ($19 to now $25) and $11·for·the larger·board ($34 to now $45). Hopefully they will honor my order when I paid $34 for each of my 2 larger boards (minutes later - after anouncing $19 and $34 ·pricing for these new items). I already placed my 2 orders and paid with Paypal when it was $34.

Take a look at this email I got back this morning from Sure Electronics about the mixup in pricing:

What does everyone think? I kind of think they should give me the 2 display boards at what they sold it to me for. But $13 (vice $20 more) isn't too bad either - shipping was horrible all the same.

Comments?

I decided to just pay the $13 via PAYPAL so that these 2 boards can get shipped out without anymore hassle.
