I have created a USB hub as extension board (as replacement of 4G modem). Currently only schematic is ready. One can install this board as replacement of 4G modem and have 4 additional USB ports.

This is really cool. It seems like the 4G modem board, even unpopulated passively connects the speakers to the system. It would be neat if this board could do the same, so the speakers would be able to function as normal without needing to modify them. ---

Wow, this is awesome! I really think the uConsole for the will be paired with my phone, so I will always have WiFi at hand. Really cool projects, following this for sure! ---

I see the speakers are no longer supported with this module. Is there space to keep the contact pads for the speakers? I’m also curious about the power draw on the 5v line. With 4 additional usb ports, how much more power draw can you put on the SYS\_5V line through the SY7215 boost regulator and AXP228? ---

did you patch the speakers through this board? ---

Thanks for the comments. I added speakers. Not sure about symbols and footprints yet. ![image](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/2X/d/d941a40dfc364eb6d159eec4ce14c6378ba0cf02.png) About power consumption I am not sure. I see 2 main solutions. 1. Limit single port current to 100 mA 2. Add external power input. Additional USB C socket for external power. ---

Maybe pinging @57Bravo will help both sides since im sure some of this info would interest them, and they may have some input on the stuff here as well. ---

I finished the PCB, need some testing still ![pcb_top](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/2X/5/54b37a980a2542c806bc9fb392fcecb3dd9e233e.png) Pads for speakers are on the bottom too. ![pcb_bottom](https://canada1.discourse-cdn.com/flex029/uploads/clockworkpi/original/2X/b/b6462bcb8ba7979d166f986eb7994588f2d97921.png) ---

Not an expert but looking at the AXP228 specs and understanding what USB drives can draw, external power seems like a good idea. Super cool design - kudos to you. ---

Yep, not going to be charging a phone from these ports… will look at SDR spec - but these will definitely drive usb keyboard wireless fobs etc. ---
