Linuxstamp Mboard 1

Introduction

This project is purely in the planning stages. There are no designs available. It is meant to be a brainstorming area. Feel free to add possible vendors.

Sensor wish list

• Oscilloscope
  • Example PC based digital oscilloscope :Project 25
• CANbus
• A/D converter with selectable ranges
• 3-axis accelerometer
• Temperature sensor
• Pressure sensor
• GPS module
  • Parallax GPS module

Communication wish list

• 802.11b/g interface
  • Sychip wifi module. The drivers aren't on the webpage. I don't know if you can get them GPL.
  • NXP wifi SiP. Again I don't know about the drivers
  • Atheros module This is what the openmoko project is using
  • Spectec has many SD card wlan modules. There is some support for linux.
• Zigbee interface
  • Maxstream zigbee module
• Cellular modem
  • Socket modems from multitech

Power supply

• POE frontend
  • A simple Isolated 5v 9 watt POE module I've tested this module, and it works well with the Linuxstamp

AVR slave

A dedicated slave processor could be helpful for many things. The main function I have in mind now is PWM outputs for servo control. I think an AVR could even be programmed through the SPI port of the AT91RM9200 (some hacking may be needed to make that work). Even if you can't programm the AVR through the AT91RM9200, it can still be an SPI slave device.

• PWM output with standard servo headers
• Counting/Frequency inputs
