  • Assembled, TESTED, and works awesome.
  • nRF905 at 915 MHz.
  • Uses Johanson 915 MHz chip antenna P/N 0915AT43A0026.
  • LEDs on all three interrupt pins for visual feedback.
  • Do not exceed 3.3V for IOin and Vin. There is no regulator or level shifting. Shouldn’t need to level shift IOout. There are six (6) inputs and four (4) output IO pins.
  • All values indicated on board are good. Three (3) LEDs and three (3) resistors are not marked, because color and brightness are by preference.
