Devkit Jumpers

Jumpers to connect M6e I/O lines to devkit.

Header for alternate power supply. Make sure DC plug (J1) is not connected if using J9.

J10, J11, J13, J15

Jump pins OUT to GPIO# to connect M6e GPIO lines to output LEDs. Jumpe pins IN to

GPIO# to connect M6e GPIO to corresponding input switches SW[3-6]GPIO#. Make

sure GPIO lines are correspondingly configured as input or outputs (see Configuring GPIO

Settings).

J14

Can be used to connect GPIO lines to external circuits. If used jumpers should be

removed from J10, J11, J13, J15

J16

Jump pins 1 and 2 or 2 and 3 to reset devkit power supply. Same as using switch SW1

except allows for control by external circuit.

J17

Jump pins 1 and 2 to use the 5V INPUT and GND inputs to provide power. Jump pins 2

and 3 to use the DevKitʼs DC power jack and power brick power.

J19

Jump SHUTDOWN to GND to enable module. While grounded SHUTDOWN pushbutton

(SW2) will break circuit and shutdown the M6e (see M6e Digital Connector Signal
