MultiSerial Shield

The Arduino MultiSerial shield will let the Arduino access a number (4 or 8 likely) of RS232 serial ports via SPI. It will have switchable TTL or RS232 levels. This project exists mainly as a debugging tool for networks of BlinkieBits, as (at least during BlinkieNet design/prototyping) it would be extremely useful to be able to receive debugging information from a whole network of BlinkieBits, rather than just one at a time.

  • Use the MAX3110 SPI UART/level shifter chip, $11ish at Digi-Key in qty. 1
