On-Module USB Transceiver Information¶
The MitySOM-5CSX module features an on-module USB transceiver, specifically a TUSB1211A1 from TI. Here is a run-down of the USB related pins on the edge connector for this interface:
| Module Pin | Pin Name | USB Transceiver Ball # | Notes |
| 242 | USB1_FAULT_N | E2 | +3.3V pull-up through 102k resistor and 470pf capacitor on module |
| 246 | USB1_PS_ON | D4 | +3.3V pull-up through 102k resistor on module |
| 272 | USB1_ID | D3 | |
| 274 | USB1_D_N | C1 | |
| 276 | USB1_D_P | D1 | |
| 278 | USB1_VBUS | F4 | 0.1uF cap on module |
