Rowan Posted March 13, 2015 Report Share Posted March 13, 2015 Very Cool... I'm tempted to buy one. Quote Link to comment Share on other sites More sharing options...
latigid on Posted March 14, 2015 Report Share Posted March 14, 2015 (edited) Heh, saw this on Muff's and was thinking the same. But the Launchpad is about the same price (8x8) and has extra buttons and tri-state LEDs. Still need to add an Arduino controller... You can buy the 4x4 Trellis PCBs for $8 each in quantity, but still only single LEDs. The silicone pads go to $4 a piece in quantity. https://www.adafruit.com/products/1616 https://www.adafruit.com/products/1611 Still, it's half the price of the Sparkfun one. https://www.sparkfun.com/products/7835 Sparkfun's PCB costs the same and is RGB LED compatible, but is unpopulated component-wise. https://www.sparkfun.com/products/8033 If the silicone pads could be had cheaply, the next thing would be to design a full 16x16 + X board or smaller ones that connect together.

Altitude Posted March 16, 2015 Author Report Share Posted March 16, 2015 what i found interesting about the trellis is the fact that it's all connected to i2c right out of the gate and although that limits you to 128 it still simplifies thing considerably on the back end. With the sparkfun kit, you still have to sort out the shift registers etc but with this, it should be good to go Quote Link to comment Share on other sites More sharing options...
Lamouette Posted March 24, 2015 Report Share Posted March 24, 2015 the hole size looks large enough to put 2 smd led on it, but the problem is to get powered enough led, looks like you need something like 10000mcd to get something visible by day, but impossible to find smd alternative.
