The Proto Shield Plus Board Layout

Lets take a look at the Proto Shield Plus board layout

Proto Shield Plus TOP side

ARDUINO SOCKETS

The UNO / LEONARDO socket accepts UNO, LEONARDO, YÚN and ZERO Arduino boards

The NANO / MICRO socket accepts NANO and MICRO Arduino boards

The MINI socket accepts MINI Arduino board
To program the MINI board, an additional USB to Serial adapter is needed
Plug the adapter into the EXTUSB2SERIAL header of the Proto Shield Plus

PUSHBUTTONS

The PUSHBUTTONS area provides 5 general purpose buttons and 1 reset button.

The 5 general purpose buttons comes by default with a resistive network connected to A0 Arduino analog pin.

If you want to use them one to one with digital input pins, a few jumpers let you to reconfigure the Proto Shield Plus to work with digital input pins.

LCD 1602 AREA

The LCD HEADER lets you to connect a standard LCD 1602 display module and drive it by default with I2C (drive LCD with just 2 Arduino pins).

If you prefer to drive the LCD with a parallel connection, a few jumpers let you to reconfigure the Proto Shield Plus to work in parallel mode.

The PV0 multi turn potentiometer lets you to adjust LCD contrast.

By means of U1 you control LCD backlight ON and OFF state.

If you do not need to use the 1602 display, the I2C I/O expander (PCF8574) can be used to add 8 digital input / output signals for your needs.
PCF8574 HEADER provides the input / output signals from the I/O expander chip.

IN / OUT and POWER HEADERS

All the input, output, 5V, 3.3V and GND pins of the Arduino board are connected to these headers.
They are on both side of the breadboarding area (avoiding “jungles” of wires).

BREADBOARDING AREA

The breadboarding area provides 1480 connection points for prototype your projects

ADDITIONAL SOLDERING PADS

More than 400 soldering pads for additional prototyping parts.

OUTPUT LEDs AREA

The Output LEDs area provides a red LED and a green LED connected by default to D11 and D12 Arduino digital pins.

If you want to disconnect them from D11 and D12 or use them with different I/O pins, a few jumpers let you to reconfigure the Proto Shield Plus according to your needs

POT AREA

The POT area provides a 10K potentiometer (with knob) connected by default to A1 Arduino analog pin.

If you want to disconnect it from A1 or use it with different analog pin, a jumper let you to reconfigure the Proto Shield Plus according to your needs

SERVO HEADER

The SERVO HEADER provide a fast connection to experiment with a servo. It is connected by default to 5V, GND and D3 Arduino digital output pin.

If you want to drive the servo with a different digital pin or an external dedicated power supply, a few jumpers let you to reconfigure the Proto Shield Plus connections to work according to your needs

ICSP AREA

The ICSP connector connects to ICSP Arduino signals: use NANO and MICRO with standard “UNO form factor” shields.

VEXT AREA

Ready for an external 7-9VDC power supply

PROTO SHIELD PLUS BOARD DIMENSION

Dimensions in mm: 185x205x30 (HxWxH)
