  • Most of these are 22 AWG, which according to http://www.engineeringtoolbox.com/wire-gauges-d_419.html means it can handle 5A. That’s assuming single core, while this is probably stranded. So I’d assume 2.5-3A to be safe.

  • Since nobody else has mentioned it, I am using SparkFun’s PicoBuck to drive this LED. I plug in a 12V 2.5A switching AC inverter to the wall and connect it to the PicoBuck (https://www.sparkfun.com/products/11850), which handles this LED just fine. It also has inputs to PWM the three channels with 3.3V/5V logic pins.

  • A new library called RadioHead was just released in April 2014 and looks like it might be easier to setup than either Mirf or NRF24.

  • Could you provide these in 8MHz?

  • I’m trying to use this board with SPI connected to an nRF24L01 for wireless communication into USB, as the receiver for a remote. But SPI is PB0-3. Only PB0 is on this breakout board, and it’s on the short edge. What happens to PB1 (SCLK), PB2 (MOSI), and PB3 (MISO)?

  • I would love to see a 3.6V zener diode. Useful for building software USB on ATtinys. See the V-USB implementation here: http://vusb.wikidot.com/hardware. This allows folks to get everything they need to build a USB device using AVR entirely on Sparkfun.
