Part of Arduino Interface
Jumper defines IO voltage for Arduino shield:
Jumper on pins 1-2: 5 V
•
Jumper on pins 2-3: 3.3 V
•
Jumper defines Flash write protection enable
or disable:
Jumper on pins 1-2: write protection ena-
•
ble
Jumper on pins 2-3: write protection disa-
•
ble
Note: flash write protection jumper should be
in write protection enabled state (pins 1-2)
during normal operation.
Jumper defines VIN connection to the Arduino
shield:
Jumper on pins 1-2: VIN is connected to
•
the Arduino shield
Jumper on pins 2-3: VIN is not connected
•
to the Arduino shield
