I want to integrate a microphone in M5CameraF that according the description should have a mic interface. I need a microphone unit small enough to fit inside the M5CameraF case.

What do you suggest?

What is the pins' type and pitch of GPIO HAT port of M5StickC? Seems this information is missing in the tech specs and would be useful to know to order proper pin headers.

@ajb2k3 thanks for the answer. The missing of power specs is a serious omission, I hope M5Stack staff will add them. Do you have tried if using the hub with multiple devices attached and with USB connector of M5Stick attached to power source it changes something?

@ajb2k3 In the UIFlow book? In what page or paragraph. I haven't seen a specific section for Groove ports hardware specs, max power supplied on the line etc.

@ajb2k3 The page with the detailed specs of various Grove ports on M5stack and M5stickC.

@ajb2k3 Could you link it here?

@ajb2k3 Thanks for the answer. Where I can check the specs of various Grove ports on M5stack and M5stickC?

Could I use I2C Hub 1 to 6 Expansion Unit (TCA9548A) with M5stickC Grove port to connect multiple units? Seems there are different Grove port versions and isn't clear the difference in the store description and what is the one on M5stickC.
