What is "Minimalduino"?

I started working on the "minimalduino" design as...
  1. a minimal hardware design for an Arduino-compatible board. At heart, it is very similar to the Dorkboard, but
  2. designed to match the form factor of the "official" Arduino boards so users can benefit from the many, many shield boards designed to fit on top. While (awesome) boards like EMSL's Diavolino are also low-cost and shield-friendly, I wanted to explore
  3. optional hardware configurations, with different power connector options (pin headers, JST connector, barrel jack, screw terminals, or mini USB jack), 5V and 3.3V power regulation and optional voltage switching and regulator bypassing, and options for crystal and caps or a resonator. I also wanted to have
  4. better shield-friendliness by placing LEDs (power and D13) and the reset switch (side switch or top switch) at the edges of the board, and lastly, I wanted the board to be
  5. single-sided, home-etchable with wide traces and minimal jumper wires. There is still work to be done to reduce jumpers, but it improves on the the S3V3 "Severino" board which doesn't match up size-wise (it's bigger), the standoff mounts don't match, and it uses a DB9 serial connector instead of the now widespread FTDI USB-serial breakout cable.

Spreadsheet: "Date Added" Column, More Boards

So many people have asked for a column on the Arduino-compatible board spreadsheet showing the date when each board was added, so I put that on the spreadsheet this week. I had to sift through the revisions, but it wasn't too much of a pain.

Also new to the spreadsheet:
  • Six boards by the Indian company Bhasha, all through-hole except for the FTDI USB chips, mostly simple designs but it's clear from the traces that the boards were reworked slightly. Interesting to see the "Severino" Single Sided Serial V3 design offered for sale, something I haven't seen elsewhere.
  • Zigduino by Logos Electromechanical is offering their first run of IEEE 802.15.4 radio-equipped boards for $70. I've been looking forward to these boards coming out, but the price seems high given that you could buy an Arduino FIO for $25 and an XBee module for $19, so $44 total, or a Freakduino Chibi for $33. I hope the high price is only for this first run and that it is lower when Logos goes into full scale production, but I also wonder if it's as easy to use as the widely available XBee modules for which there are many example sketches available. It does have XBee "Pro" capabilities though, and I'm not familiar enough with 802.15.4 to really compare it to other offerings. I look forward to more complete documentation on its specs along with full design files since it's unclear what its equipment and capabilities are.
