Grove - Mega Shield

Introduction

Grove - Mega Shield is a extension board for Arduino Mega and Google ADK. We have standardized all the connectors into 4 pins(Signal 1,Signal 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 Analog 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
  • Dimensions: 92.8 mm X 57.2 mm.

Function Block


The purpose of the Grove - Mega Shield is to allow easy connection of Xduino Mega/Google ADK input and output pins to the Grove units.

Each socket is clearly labelled with its matching I/O pin. the Grove - Mega Shield can be divided into four sections: Reset Button, Analog Area, Digital Area and Power Area. Please consider the following diagram:

The Digital Area of Grove - Mega Shield can also be partitioned into four sections according to different function of GPIO: IIC( 3 connectors ), UART( UART0-3 ), PWM ( PWM2-13 ) and ICSP( not connector ). Please be aware that PWM have two ways of appearance: 3Pin 2.54mm Header and our standard 4Pin 2mm connector. Those two forms of appearance serve different purpose, 4Pin 2mm connectors can connect to our standard Groves while 3Pin 2.54mm Header can connect to Servo, Ultra Sonic range measurement module and Electronic Bricks. Please be aware that When using 3Pin and 4Pin modules on PWM at the same time, Do take extra attention in case of multi-using the same GPIO. Please refer to the following diagram:

Help us make it better

Thank you for choosing Seeed. A couple of months ago we initiated a project to improve our documentation system. What you are looking at now is the first edition of the new documentation system. Comparing to the old one, here is the progresses that we made:

  • Replaced the old documentation system with a new one that was developed from Mkdocs, a more widely used and cooler tool to develop documentation system.
  • Integrated the documentation system with our official website, now you can go to Bazaar and other section like Forum and Community more conveniently.
  • Reviewed and rewrote documents for hundreds of products for the system’s first edition, and will continue migrate documents from old wiki to the new one.

An easy-to-use instruction is as important as the product itself. We are expecting this new system will improve your experience when using Seeed’s products. However since this is the first edition, there are still many things need to improve, if you have any suggestions or findings, you are most welcome to submit the amended version as our contributor or give us suggestions in the survey below, Please don’t forget to leave your email address so that we can reply.

Happy hacking
