Screw Terminal Block (J4); Jtag/Swd Connector (J3) - Arduino Portenta Mid Carrier Product Reference Manual

4.3.3 Screw Terminal Block (J4)

The screw terminal block connector J4 is used to power the Portenta Mid Carrier and to expose the CAN bus
interface (CAN1) to the user.

Reverse polarity protection: IN 5V pins of the carrier's screw terminal block (J4) and breakout header
connector (J15) do not have reverse polarity protection. Double-check the polarity of your power supply
before connecting it to the carrier to avoid damaging it.

4.3.4 JTAG/SWD Connector (J3)

The JTAG/SWD connector J3 can be used in the Portenta Mid Carrier to test and debug the connected Portenta
family board.
