{AVR|PIC} Stamp dev board is simple, fast, has lots of I/O and serial

Thursday, January 3rd, 2013

Bertho is working on an {Avr|Pic} Stamp development board for his local hackerspace. These USB interface boards are based on the ATmega32A and PIC18F46K22 microcontrollers. Both boards use the MCP2200 USB-to-Serial IC to interact with computers over a USB virtual COM port. There are often things you want to test...

Dangerous Prototypes has a stamp for your hackerspace passport. To get a 'visa', find us at the Open Hardware Summit, Maker Faire, or your local hackerspace. We studied several actual passport stamps when making the design. It has a few official boxes to tick with a (different-colored) ink pen, ostensibly...
