Hey Hellraiser, Unfortunately, these 4x20 PLED's are no longer made as there was not a high demand for them (that's according to the...
Just make sure you check the datasheets for the output of the kit. Some may pull the output to ground or up to VDD, or be momentary or latching....
I do believe you can order development kits from Atmel that use these chips (although I believe the Q110 has been discontined). Atmel bought out...
