New hardware!

After a long struggle (which isn’t over yet), my new hardware finally arrived:

Designed to be as small and lightweight as possible: the weight is 8.6grams with a size of 46×59mm. The cool thing is that the profile of this board is only 6mm thick. This makes it also perfect for small UAV’s.

This high-precision yaw rate gyro makes this board a nice candidate for your next quadrocopter as well :-)

Its features are an extention of my previous versions:

  • 6DOF IMU (3 gyros and 3 accelerometers)
  • 16-bit pressure sensor for height
  • can control 6 servo
  • RC-transmitter input through PPM or PWM (4 channels)
  • a push button
  • 2 LEDs
  • 4MB flash for datalogging and configuration
  • 256kB flash for code
  • works with EB-85 GPS and other (4-pin) GPS modules
  • connects to your PC using the standard FTDI USB data cable
  • SPI, I2C, UART headers available for communication with other devices

And last but not least: the software

  • Easy to use libraries for all hardware
  • 11 simple demo applications for every hardware component
  • a simple autopilot
  • a more complex autopilot using FreeRTOS (work in progress)
  • all code nicely documented

However, still a lot of work has to be done. Attitude estimation needs to be improved, and a nice configuration tool would rock! It would be great if some people would show interest to join me in this effort!
