I'm pretty sure that Pololu has several versions available= .. Just checked: yep. USB versions ranging from 6-channel ($20) through 24 channel=20 ($50). Partial kits are available for about $1 less - these are the=20 same as the above versions but are shipped with the header pins not=20 soldered to the board (headers are included in the package). I think highly of Pololu - excellent products at awesome prices. dwayne At 07:17 AM 5/7/2015, Carlos Marcano wrote: >Hi all. > >I want to work on something that I have put on hold for a while.
