Has anyone found something like a powered USB hub in hat form for a Pi zero 2 w? The X302 seems like the right idea, although:
The ultimate goal is a midi synth with USB inputs for the keyboards. It needs a screen and DAC, and for now I'm building with a Pirate Audio headphone amp but the USB needs to power the keyboard too. |

https://www.amazon.com/dp/B01K9IVUYM I bought that earlier this year. Works great. Have two RTL-SDRs hooked into it along with a Meshtastic node. It mounts under the Pi Zero so you still have your headers available for other stuff. |

Thank you. That looks perfect. I'll give it a shot. |

The only tricky bit is forcing the Pi's USB port into host mode by default. I thought the hub was defective but it worked when I put an OTG adapter into the micro USB port. The default auto detect behavior doesn't work with this since it doesn't connect to the OTG pin. I had to edit
