Arduino — Sensor Shield V5 0 Manual

The Arduino Sensor Shield V5.0 is a popular expansion board designed to simplify wiring by breaking out each I/O pin into a 3-pin header (GND, VCC, Signal)

External Power (Jumper OFF):

By removing the jumper and connecting a 5V–6V source to the blue screw terminal, you can power high-current devices like servos independently. This prevents electrical noise from resetting the Arduino. arduino sensor shield v5 0 manual

Common Troubleshooting (Your "Manual" Fixes)

• Location: Plug your OLED (SSD1306) into the I2C block.
• Wiring: It supplies VCC, GND, SDA (A4 on Uno), SCL (A5 on Uno).

Jumper Removed:

The digital pin "V" pins are isolated from the Arduino. You must provide external power (typically 5V–6V) via the blue screw terminals to power high-draw devices like servo motors. Technical Specifications Sensor Shield for Arduino UNO - Rajguru electronics The Arduino Sensor Shield V5

Servo headers

This is the most common point of failure for beginners. Look near the for a small 2-pin or 3-pin jumper (sometimes a sliding switch). Location: Plug your OLED (SSD1306) into the I2C block

• VCC selector jumper — choose between 5V or 3.3V supply for module headers.
• VIN/RAW jumper — link external barrel-jack power to shield VCC.
• Servo power isolation pads — cut or solder to isolate servo power from Arduino when using separate supply.
