454 mhz chumbyhackerboard



Just stumbled upon this amazing board. Would be really interesting to use it for a quad project. What do you guys think??


  • Freescale iMX.233 processor running at 454 MHz
  • 64 MB onboard RAM
  • Comes with 512 MB uSD card with 100 MB Linux installation all ready to go
  • 3.3V I/O pins can talk to most sensors, motor drivers, etc. No struggling with 1.8V levels.
  • Low power, fanless ARM926 core draws only 200-300 mA
  • Onboard GL850G USB hub draws 100-200mA
  • Built-in Lithium Ion/Polymer battery charger and 5V boost converter for portable projects
  • Three USB port jacks!
  • 1.5W mono 4-16 ohm speaker amplifier (0.1" JST onboard connector)
  • Microphone input (0.05" JST onboard connector)
  • LCD controller with 2mm output port
  • 3.5mm A/V output jack with stereo audio and NTSC/PAL composite video
  • Back of board has GPIO outputs on 0.1" header spacing, plug in an Arduino proto shield (Beta version only, Final boards don't have this)
  • Quadrature encoder connections onboard
  • 5-way joystick on-board
  • MMA7455 3-axis +-2G to +-8G accelerometer on-board
  • 3.3V TTL serial port for easy shell access
  • Full GCC toolchain is ready for you to download and get crackin'!

copterLoader - firmware uploader


This program downloads precompiled firmware for the arducopter and automatically uploads it to APM. No need to install arduino, libraries etc.

Hopefully this program will make it easier for those of you who fly the arducopter, but don’t have an interest in programming. Using this program you don’t have to install arduino and build the code yourself.

Right now I only uploaded one version (version RC02) of the code. This is the one I'm flying. Nothing extra (gps, mag +++). If people like it I will upload more. And the user can chose witch one to download right in the software.

Remember this is the alpha version, so there might be some bugs. Please give me feedback (bugs or suggestions)

Arduino hex uploader (XLoader)

I’ve made a small program that can be used to upload your own c code to arduino boards using the bootloader. That means you don’t need a flash programmer. I
made it for my own use and found it pretty useful. So now I’ve
made a more user friendly version..

To use it simply start XLoader.exe, pick a hex file and press upload. That’s it.


Hope you find it useful... Or am I the only one using AVRstudio to program my uav??

As you can see it's still early alpha, so there might be some bugs. Please contact me about bugs or suggestions.
