Power supply concern
Hello As I am new to electronics and unsure about power supply required, I wanted to if the 3.3V cell coin battery is enough or safe to power up the tiny shield microprocessor, tiny shield bluetooth module as well as accelerometer shield all at once as a wearable? ( all these items purchased from the website). Your help will be really appreciated. Thank you

  • Yes, the coin battery will power those three modules, but for how long I'm not sure.

The TinyCircuits TinyDuino is an Arduino compatible board in an ultra compact package. The TinyDuino processor board is roughly equivalent to the Arduino Uno board – same processor, same signals brought out to a shield connector. In fact, most Arduino sketches will work as is without any changes.


  • Atmega328P processor (same as is used on the Arduino Uno)
  • Reset switch
  • Status LED
  • 8MHz ceramic resonator
  • External power supported with a 0.1″ power connection holes
  • Supports automatic switching between +5V and VBATT (if +5V is present, it will be used instead of the battery)

Note: To program this board, you need to use the TinyShield USB Board

Note: This board does not include a voltage regulator – do not supply more than +5.5V to VBATT or the +5V signal or you will permanently damage the board and ruin your day.
