Hi, I'm working on a project that uses many I2C devices but having trouble increasing the bus capacity.
The project uses an Arduino and I have a PCA9507 bus extender connected to the Arduino and my devices connected to it.
https://www.nxp.com/docs/en/data-sheet/PCA9507.pdf
This works really well but of course up to a point. With this I can connect 10 devices using 1ft USB patch cables between everything. All connections are via USB cables. Without the PCA9507 I can only connect 2 or devices so it definitely works.
But I need more, my thought was just keep putting these PCA9507's inline to recharge the bus however it doesn't work. It doesn't crash the bus but does nothing to allow more capacitance.
Any ideas I can try?
Thanks
