“just another Arduino clone”

Goals of this project

  • learn more advanced electronics developement
  • try to build own HW kit for our Arduino workshop's
  • take out ftdi chip from mother board

Some story around this project

many of our members and friends are using arduino for building many nice projects but we are not satisfied with price of “full” arduino boards

So I have idea to make arduino without ftdi chip on board and make boards itself cheaper

During development of this boards we recieved lot of questions about organizing arduino workshops for beginners

Electronics overview and summary

Processor : atmega168 ( in future atmega 328 , distributor have lack of those :-/ ) Power supply : direct from USB or from linear stabilizers ( switchable with jumper) Speed : 16 MHz

Pros:

  • fully arduino compattible pinout
  • simple programmer connection
  • price :)

Cons:

  • missing ICD header ( design issue )
  • no 3.3V output from board ( whole board is pure 5V logic)
  • external powersource header pin is not connected

I personally think that for beginners is this board highly sufficient

HowTo Configure Arduino software

  • install and start Arduino software
  • Depending on CPU variant you've received configure your software ( Tools→Board→ATmega 328 )

Projects

RepRap

Experimenting and improving can be pretty expensive. If you would like to support RepRap project you can donate us on consumption goods.

Polylactic_acid (whole roll, 2.3kg), thermoplastic made from sugarcane or cornstarch used for printing all that awesome things :)

Acrylonitrile_butadiene_styrene, another thermoplastic material

Brmduino (not available anymore)

during tuesday meetups ask for Sargon or Brmduino ;)

price :

  • Brmduino kit →
  • Brmduino only →
  • FTDI board only →

this is really cost of developement costs + hand soldering on ftdi board
