Align the male header pins on the bottom of the Sensor Shield V5.0 with the female headers on your Arduino Uno or Mega.
The order of pins on the 3-pin headers is standardized. From top to bottom, the sequence is usually GND (Ground) , VCC (Power) , and S (Signal) . Always double-check the silkscreen labeling on your specific board, as some manufacturers label the signal pin on the bottom.
: Every I/O pin (D0-D13 and A0-A5) is broken out into a Signal (S), VCC (V), and Ground (G) stack. Operating Voltage : Typically 5V-6V.
Based on technical documentation from ProtoSupplies and PCBSync , the board features: : Standard Arduino shield footprint (57 x 57mm).
If you are just starting out with this shield, I can to help you test the digital inputs, analog sensors, and servos.
is designed to fit directly on top of an Arduino Uno R3 or Arduino Mega, making it a seamless integration process.
Beyond general I/O, the V5.0 includes dedicated headers for common communication modules and displays: Sensor Shield V5 Arduino
| Block/Pin(s) | Description | | :--- | :--- | | | Features D0–D13 . Each pin is brought out to a 3-pin header (S, V, G). Among these, D3, D5, D6, D9, D10, D11 support PWM, making them ideal for servos, LEDs, and motors. D13 also drives the onboard yellow LED. | | Analog I/O Headers | Features A0–A5 . Each is brought out to a 3-pin header (S, V, G). These inputs can also be used as additional digital I/O pins if needed. | | I2C Interface | A dedicated 4-pin header (labeled IIC) for I2C devices, connecting to the Arduino's SDA (A4) and SCL (A5) pins. | | UART / Serial Header | Provides access to the hardware serial pins RX (D0) and TX (D1) for programming or debugging. | | URF (Ultrasonic) Header | A dedicated 4-pin port for connecting standard Ultrasonic Distance Sensors like the HC-SR04. | | Bluetooth Header | A dedicated 6-pin header (labeled BLUETOOH) for plugging in HC-series Bluetooth modules. | | SD Card Interface | A header providing the SPI bus ( D11-D13 ) and the Chip Select pin ( D10 ) for connecting an external SD card module. | | APC220 Header | A dedicated 4-pin port for connecting APC220 wireless RF modules for serial communication. | | LCD Interface | A 14-pin header for connecting parallel LCDs (e.g., 1602) and a 6-pin header for serial LCDs, simplifying display integration. |
Issue 2: I2C devices (like an OLED screen) are not being detected.
Located next to the external power terminal is a 2-pin header labeled . Its configuration dictates how the "V" rows on the digital pins receive their power:
