Hello again folks,
So I’m using the Teensy 4.1 for my synth/midi controller project now which has USB Host pins on board. Rather than accessing these pins by way of this special USB cable, I’d like to just have a proper USB port on my PCB. However, the pins for the USB Host on the Teensy 4.1 are tucked into the middle of the board, so before I create the wide traces at the proper impedance for the differential pair, I’m going to have to run some tiny traces past other pins that are very close to each other.
I’ve attached some photos for reference here below. The traces will probably need to be around 0.2mm wide and they will pass beside pins which will be also be 0.2mm from the trace. The pins the D+/D- pair will be passing by are carrying audio data signals. Will this cause interference on my incoming signal? Or is this ample space? I’m just running USB MIDI into the USB Host pins, so we’re still at USB 2.0 speeds, nothing major. The only other option would be just running some wires from the Teensy onto my PCB, bypassing the need to create narrow traces, but ideally I’d like to avoid that.
Any advice would be greatly appreciated, thanks in advance!
