Description Mega Shield is a extension board for Arduino Mega and Google ADK. We have standardized all the connectors into 4 pins(Signal 1,Singal 2,VCC and GND) 2mm connectors and keep some of the 3pin(Signal, VCC and GND ) 2.54mm headers for Servo and Electronic Bricks , which simplify the wiring of electronics projects. The 4pins buckled connectors also make the wiring situation more stable. The Mega Shield includes Digital 0 - 21 and Anolog 0 - 15; We abandon Digital 22 - 53 for easily installing Mega Shield with Xduino Mega/Google ADK. Features - Arduino Mega1280/2560 compatible - Grove compatible - Google ADK compatible For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product. https://elecena.pl/product/9696244/103020027-arduino-shield-grove-mega-shield-v1-2 2017-08-05 https://elecena.pl/product/9696244/103020027-arduino-shield-grove-mega-shield-v1-2 2018-01-25 https://elecena.pl/product/9696244/103020027-arduino-shield-grove-mega-shield-v1-2 2021-05-21 https://elecena.pl/product/9696244/103020027-arduino-shield-grove-mega-shield-v1-2 2022-01-09 https://elecena.pl/product/9696244/103020027-arduino-shield-grove-mega-shield-v1-2 2022-06-08 https://elecena.pl/product/9696244/103020027-arduino-shield-grove-mega-shield-v1-2 2022-10-20 https://elecena.pl/product/9696244/103020027-arduino-shield-grove-mega-shield-v1-2 2024-06-17 https://elecena.pl/product/9696244/103020027-arduino-shield-grove-mega-shield-v1-2 2025-02-08 https://elecena.pl/product/9696244/103020027-arduino-shield-grove-mega-shield-v1-2 2026-02-14
