Table 3: EVK-ODIN-W2 connector description
On the EVK-ODIN-W2 evaluation board, there are two sets of connectors for accessing the ODIN-W2
pins. The socket connectors (J2, J3, and J4) placed closely to the board edges are connected to ODIN-
W2 through level shifters and have 3.3 V I/O level. The pin header connectors (J22, J23, and J24) are
directly connected to ODIN-W2 and have 1.8 V as I/O level.
⚠
Be careful to connect only the 1.8 V level or 3.3 V level pin in a pair if the ODIN-W2 pin is used as
input. For example, A14 on J22 and J3.
