Let's Make Robots!


Intoroducing R-Dev-Ino

R-Dev-Ino is a Robotic Development Arduino compatible board, easily stackable. If you want to build a more complex robot, you need to modularize it. Instead of designing specific boards for each module, I have designed a multipurpose configurable board with a small prototyping area and an I2C connector made so the boards can be stackable side by side, one on top of the other like this:


  • 3 pin headers for all I/O pins
  • power to the 3 pin headers is user selectable by manually connecting a pin to the desired power voltage (Vcc or Vin)
  • small prototyping area for board customisation
  • headers for SPI programmer and external FTDI Basic programmer
  • header for UART
  • mirrored dual I2C connector to allow stacking right on top or side by side
  • regulated and unregulated power connectors, with small regulator on board
  • power LED
  • board size 3" x 1.65"
  • user can use either a crystal or a ceramic resonator (8 or 16 MHz)


The board was designed using Eagle CAD software. It is released under the Creative Commons Attribution Share-Alike 2.5 License. You will be able to order boards from seeed_studio very soon!

To program any board, use a FTDI Basic board from SparkFun:

This is an interesting variation on the Roboduino theme. Just from what I see in the photo it looks like you can connect a USB-Serial adapter to it to program from the Arduino environment? I dropped by Seeed to see if they had it, as far as I could tell they don't have them yet. :-(


I made the required documentation for the Open Project at SeeedStudio, but then I discovered I made a mistake when I designed the board so I asked them to send all the remaining boards to me. I forgot to reverse the Rx and Tx signals at the FTDI connector. Easy to fix, but I can't have them sell a defective board.

However, when the boards will be in my hand in a few days, I'll give away a couple of boards to people that don't mind cutting 2 traces on the top and solder 2 wires on the bottom, and of course, pay the shipment. You would pay the shipment anyway if you would order the boards from SeeedStudio.

I will update the page with pictures of a few modules I'm using on my robot. 

Haha, I've done that! I have a couple of my SpeakJet shield boards like that. I had selected axial capacitors in the Eagle editor rather than the radial type I wanted to use. The board is perfectly fine, but the spacing is wrong for the capacitors I am using in the kits. I didn't realize it until a couple hours later, but since I had used BatchPCB, they won't cancel an order after its been submitted. At least I got only two as this was still during my "production prototype" phase, and I generally like to have a sample in hand to test before I order a huge batch of them (even *with* a month turnaround).

I would be interested in a couple of your boards though. As you already guessed, I don't mind modding a board from time to time :-) We can chat more about it later after you get them in!

I just received 6 boards in the mail, so I would like to trade one board for one of your SpeakJet shields (from a non perfect batch). If you would like that, send me a PM with your address.
