Ramiro Pareja Veredas of Spain wanted a business card that would make an impression. His creation can be converted into a USB drive by punching out two of the corners. It can store data, works as an oscilloscope, datalogger and PIC trainer, and packs the CPU power of a Spectrum ZX. Here are the specs:
- 16 bits microcontroller PIC 24FJ64GB002 @ 32 MHz (16 MIPS)
- 64 KB of Flash and 8KB of RAM. External SPI or I2C memory optional (up to 32MB)
- Up to 11 digital I/Os available (Four of them tolerant to 5 volts)
- Up to 4 analog channels.
- ICSP port for debugging and programming. The 3 pins of the ICSP connector can be also used as GP I/Os.
