What's RainbowDuino?

A valuable duino with extensive control capacity, for quantity project usage. Estimate price $8-$15

Features:

No on-board USB-UART chip - Trimmed for cost reduction, Separate UartSB or wireless module will be provided for USB connection.

MCU to be mounted - Program offline and plug in, you may also choose any compatible MCU you prefer to use.

Extensive Control capability - Multiplexed I/O port with 74HC595 [ch65288]or more integrated bi-directional ICs, suggestion welcomed)

Easy Cascade - Specially designed I2C port, DC in& Out,

Applications:

Control over LED matrix or Robotic.

Pending for suggestions.

  1. Is there a inexpensive IC more powerful than 74HC575? Maybe Bi-direciton multiplexer with more channels.

  2. How about more UART?

  3. How about CAN?

Thanks for any suggestion or concerns ^^

What will this offer that the existing Arduino, FreeDuino, Boarduino, etc. do not?

it can drive RGB matrix directly,
cheaper.
