TinyDuino Power Requirements
- Voltage: 3.0V - 5.5V
- Current: 2.5 mA (Typical Quiescent Current Mode).
- A0 - A3 - Audio Input (Analog) to the amplifier. The pin is dependent on which Wireling port this board is plugged into.
- 9mm x 16mm (.35 inches x .63 inches)
- Max Height (from the lower bottom of Wireling to upper top Wireling Connector): 3.70mm (0.15 inches)
- Weight: 1 gram (.04 ounces)
- You can also use this shield without the TinyDuino – modifying the connecting cable by removing the opposite connector and stripping/tinning the wires, you can solder the connector cable to any other microcontroller board of your choice!
