OSOYOO Pin Status Shield V1.0 for Arduino

Overview

The OSOYOO Pin Status Shield is a circuit board designed for Arduino UNO Famlily, it adds LED indicators for each GPIO port, so you can use the indicators to know the status of the pins and easily verify your prototype code without even wiring it up. This Shield is ideal for both beginners and experienced developers. Whether you’re working on educational projects, prototyping, or advanced development, this board provides robust support and flexibility.

Compatible List

• Arduino UNO Family(Arduino UNO R3, Arduino UNO R4 Minima,etc..)
• Arduino Leonardo
• Arduino Zero
• Or other pin-compatible boards or clones.

Note:

This shield does not have an onboard power connector and requires an Arduino base board to function properly.

Features

• Compatibility:
  • Supports all Arduino Uno boards and their clones, as well as all other Arduino development boards with pin configurations identical to the Arduino Uno.
• LED Indicators:
  • Each GPIO port has an LED indicator to display the status (high/low) of the pins, making it easier to debug and verify code without additional wiring.
  • Independent LED, The status LED is driven by the chip instead of the GPIO so the GPIO will not be affected.
• Easy Connectivity:
  • 2.54mm pitch pin headers and screw terminals for seamless connection to sensors, servos, and other peripherals.
  • On-board 3-pin interfaces with V and GND pins for easy sensor or servo connections.
  • Provide additional VIN/3.3V power pins.

1.Arduino board connector: Please pay attention to the orientation of the Uno board when using it. Improper insertion may cause circuit board burnout or irreversible damage.

2.LED indicators: LED on if GPIO outputs/inputs high level, LED off if GPIO outputs/inputs low level.

3.2.54mm pitch pinheads:  The S terminal directly connects to the Nano board, it comes with 5V and GND pins for easy connection to sensors or servos.

4.Screw terminal: Connect to all GPIO headers of the UNO boards, 2.54mm/0.1in pitch

5.Power Indicator

6.External power out pinheads: Provide additional VIN/3.3V/5V power pins.

ASSEMBLY

When inserting, please pay attention to the boards‘ orientation，ensure the Arduino uno board is correctly connected before applying power to the power supply interface to avoid damaging the board due to misalignment.
