I bought a Piano HAT and a Drum HAT, as well as a Mini Black HAT Hack3r to connect them both to a Pi. Do I just mount both HATs on the landing area pins, then run the ribbon cable from the top pins to the Pi? Also, the top landing area is big enough for a pHAT, but not a HAT. Is there a good way t…

The Mini Black HAT Hack3r was designed for a pHAT and a HAT or two pHATs, so you’re right- there’s overlap and the Piano HAT/Drum HAT wont fit together. All mine have gone walkies, but I don’t believe the full-sized Black HAT Hack3r fits two HATs either. It was a productisation of something we use…

You could use the larger version but the boards would still overlap slightly, though not a huge deal for those 2 specific HATs. You’d also have to fit a female header in the middle ‘lane’ though and use the ones either side to plug the HATs. Here’s a pic: [image] … whether that is worth investi…

Old ribon cable might do the trick for connecting two HAT one Pi … with caveats: You need to avoid cable select for master/slave, so the ribbon cable need to be without twist. IDE connector are of the wrong gender for HAT, you can use long pin to do two gender changer Ribbon cable is flexible, so …

Here is my gender changer solution for Pi 40 pin connector: https://twitter.com/DavidGlaude/status/718575909729656832 Here it was to correct a mistake… but it works with ribbon cable connector too.

It doesn’t seem like there’s a great way to mount 2 HATs at once, which is too bad. I originally got the idea from the Drum HAT product description: “Works with Piano HAT - We made sure Drum HAT and Piano HAT could be used together on the same Pi. All you need is a little creative wiring or the hel…

Another option is to use a couple of Mini Black HAT Hack3rs and just use jumper wires to connect the appropriate pins on the two MBHHs. This way you can have the two HATs sitting side by side. You could even run the wires underneath the MBHHs and mount them both on a piece of perspex if you wanted i…

[quote=“brentwomble, post:6, topic:2344”] Regarding wiring, do I just mount both HATs on the landing area pins, then run the ribbon cable from the top pins to the Pi? I’m guessing this works as long as the 2 HATs/pHATs don’t use the same pins.[/quote] sort off. I2c is special in that it uses the s…

@RogueM That pinout reference is super useful! What’s the workaround for getting the pHAT DAC and pHAT Unicorn to work together? -Brent
