USB Pins
USB communication can be performed over 2 pins of B2B connector JM4 as detailed in Table 3. Ensure resistors R3 and R4 are populated to connect USB B2B pins B2B_D_P and B2B_D_P to USB lines D_P and D_P respectively.
pin number | pin name | signal name | description |
|---|---|---|---|
4 | B2B_D_P | D_P | USB data + (D+) |
6 | B2B_D_N | D_N | USB data - (D-) |
