Expansion Connector (X6)
Figure 18: Expansion Connector X6
Expansion connector X6 provides an easy way to add other functions and features to the
phyBOARD-Regor. Standard interfaces such as UART, SPI and I
2
C as well as different supply
voltages and some GPIOs are available at the expansion female connector.
The expansion connector is intended to add specific functions with custom expansion
boards. This expansion board is developed together with the newest version of the carrier
board.
The pinout of the expansion connector is shown in
