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

• A/D converter with selectable ranges
• 3-axis accelerometer
• Temperature sensor
• Pressure sensor
• GPS module
  • Garmin 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
• Zigbee interface
  • Maxstream zigbee module
• 900Mhz radio
  • CC1100

Power supply

• POE frontend
• +/- 15v for +/- opamps and for LEM current sensors
• +5v for 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
