- Raspberry Pi Compute Module Motherboard
- Continuation from the Compute Module board from last year
- Added the PCM5122 audio DAC
- Learning about USB HUB design
- TUSB2046B
- TPS2044 for overcurrent protection
- USB spec says only 120uF cap per hub required but 100uF per port is recommended with low ESR
- USB DM/DP signals require around 27 ohm termination resistors
- Optional filter of 22pF recommended for EMI suppression
- This creates a “low pass” filter with a cut off of 267.9 MHz
- 12M bit/sec full Speed USB 12MHz, well under this cut off
- Rapid Fire Opinion (R.F.O.)
