  • Hey Sparkfun, just wanted to let you guys know that the MISO and MOSI pins on the SPI headers for the RG Matrix backpack are switched around. The “input” header should have MOSI instead of MISO. The schematic is also incorrect.

    I picked one of these up a few weeks ago for a project and couldn’t figure out why it wasn’t working. I ran a wire to the other header of the backpack and it works fine, but this works terribly for any sort of backpack daisy-chaining.

  • Has anyone else actually bought this? I seem to be having problems with the pinout, as it looks backwards.

  • The only thing that’s sad here is the number of complaints people are having about this. I think it’s great what SF has been doing for the community. Everyone should be grateful that they have the opportunity to get something back from a great company.
    Sure, I was waiting around for 2 hours trying to get connected, but regardless of whether I got the discount or not I was going to get some parts anyway.
    I changed the LED on my mouse in between server timeouts. ;)

No public wish lists :(
