outside of the published operating range for the active devices may cause degraded
performance or damage the board.
5.2.1.4 Option 4: Pin Headers
EK-RA6M2 board can also be powered through the following pin-headers.
• J1 (pin J1-15 for +3.3 V, pin J1-17 for Return)
• J2 (pin J2-10 for +3.3 V, pin J2-12 for Return)
• J4 (pin J4-37 for +3.3 V, pin J4-36 for Return)
Copper jumper E35 must be open for any of these configurations.
The pin headers supply voltage directly to the RA6M2 MCU, the S124 J-Link MCU, and
other on-board circuitry. Use caution to ensure that any voltage connected in this
manner meets the power requirements for the active features. Power sources that are
outside of the published operating range for the active devices may cause degraded
performance or damage the board.
See section 5.5, Pin Headers for more information on the Pin Headers.
