Part of Arduino Interface
X83 Jumper 3 pin SMD Jumper defines IO voltage for Arduino shield:
• Jumper on pins 1-2: 5 V
• Jumper on pins 2-3: 3.3 V
X1500 Jumper 3 pin SMD 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
: flash write protection jumper should be
in write protection enabled state (pins 1-2)
during normal operation.
X82 VIN Separation (power sup-
ply, 24 V DC)
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
