  • Thanks, Sparkfun! Good luck mopping up that pile of goo that is your server rack :)

  • Yeah it can output PWM, on multiple channels. (these or attiny45's are what power the BlinkM RGB modules)
    I'm not sure if you can get the bootloader on them, but they have enough space for it.
    I broke down and got a USBtiny ISP programmer, but you can program with an Arduino board if you have one. Here's some info I was looking into regarding that:

  • Hi Dimitris,
    This micro has two PWM outputs by default, and it can drive up to 5 or 6 PWM using software PWM. However, each RGB LED will need 3 channels, bringing your total needed to 12 (4 x 3) outputs.
    You might want to check out an attiny 2113 or atmega 328P (used in the recently updated Arduino Uno). Alternatively, you could get a TLC5940 16-channel LED driver, and interface with that via serial from a small micro like the attiny13 (here) or the attiny85.
