Xadow GSM Breakout

Introduction

The Xadow GSM Breakout draws out 30 pins from the 35 pin Xadow connector to five rows of 0.1 spaced holes with 0.1 spacing between adjacent rows. If you solder wires or through-hole pin headers directly to the breakout pads, you can easily access: - Up to 16 General Purpose Inputs/outputs (GPIOs) - Interfaces like SPI, I2C, UART, etc. - Pinout related to peripheral devices like speaker, audio headphone and microphones

Hardware Overview


How to use it


Pin Definitions


  • If your project is built with Arduino IDE, please refer to the “Pin Definitions for Arduino IDE”.
  • If your project is built with Eclipse IDE, please refer to the “Pin Definitions for Eclipse IDE”.

Notice


  • Some pinout might be occupied if the corresponding module is operative in the system. Please check the availability of the pinout of the Xadow GSM Breakout before using it.
  • And also, do make sure you know exactly about the voltage level at each pinout (2.8V or 1.8V), irreversible damages might occur if you mismatch it with a system working at a higher voltage level.

RePhone Community


We’ve been looking for a better place where our backers (RePhone Users) can sit together, warmly and comfortably, have conversations about RePhone, discuss technical problems, share ideas/projects, and give feedback on the modules’ development in the future. And then here we go, the RePhone Community.

Now join us in the RePhone Community! Together we seek answers, make interesting stuff, care about each other, and share our experiences.

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
