  • The 50mA driving the LED is not coming from the Arduino pin, but from the 5V supply. The point of this board is so you don’t draw that amount of current from your Arduino pin and damage the chip. In this case, it is more in the realm of 10mA which the chip can easily handle.

  • any thoughts on using this as a lightweight light source for camping, inside or outside of a tent? can 2 wires be driven directly from the 3V inverter? what kind of power consumption are we looking at?

  • when i plug it into my computer, it says “USB Device not recognized”. i went into the device manager to try to install a driver and it says the best driver for the device is already installed. anyone have any suggestions?
