We have been on extended blog-vacation. Now we’re back!
The Sparkfun product blog just posted the Seeduino Film board, a small package, modular Arduino that has a flexible circuit connection between each of the units. The base unit has three modules, a mainboard, housing the chip, serial connection and analog ports; a breakout for digital ports and additional I2C port; and nicely enough a li-po charger breakout. This addition makes it the same price as a comparable Lilypad with charger.
The flexible connectors and small size mean that this can be used for wearable applications but it can also be paired with headers and put on a breadboard as a normal prototyping device.
