KEYESTUDIO 10PCS Proto Shield for Arduino Mega, Double Sided PCB Prototype Shield Solderable for Arduino Mega R3 2560

Good Value PCB Diy Kit-contains 10 pieces prototype circuit boards and comes with a beautiful box.
Perfect size for arduino mega board-seamlessly plug it into the mega board with the pin headers and 4 mounting holes at the corners.
High Quality-solid and sturdy glass fiber FR4 material proto boards, thick and double sided.
Very Convenient-clear yellow pin labels and pre-tinned plated holes on board make you easily solder components and sensors for your projects without mistakes.
Hole-pitch: 2.54mm/ 0.1inch, Hole-diameter: 1mm/ 0.04 inch, allowing easy attachment of medium sized wire.

use: 1. +5 +5 is the positive input port of the power supply, which can be connected to a voltage of 3.3V~5V.
2. GND GND is the negative input port of the power supply. OUT OUT is the signal output port, which is connected to the I/O port of the single-chip....
For other main control boards or higher-level main control boards (such as Arm), if you need to set the I/O port to input/output mode, you must set it....
Note: For Arduino players should set the MCU's I/O port to input mode/receive mode, otherwise it cannot be used..

ATmega328 microcontroller with Optiboot (UNO) Bootloader. Rev3 shield compatible..
Program with a USB Micro-B cable using the Arduino IDE platform: Plug in the board, select “Arduino UNO” and you’re ready to upload code.
Hardware peripherals you know and love: 20 Digital I/O pins with 6 PWM pins, 6 Analog Inputs, UART, SPI and external interrupts.
Broken out the SDA, SCL and IOREF pins, so it will be compatible with future shields Power over USB or through the barrel jack 7 to 15VDC.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong..
