Features

  • The board has mounting holes and fits the nice box. I would plan a little refine it.
  • RFM69 and NRF24L01 SMD footprints
  • Separate LDO's for radio and atmega
  • Separate 3.3V and 5v i2c buses
  • Separate 3.3v and 5v SPI buses (D7 is converted to 3.3v as external CS pin)
  • A lot of external pins
  • SPI flash and ATSHA204a onboard
  • Reverse polarity protection
  • A lot of sensors onboard (AM312, bh1750, bmp280, si2101, si1132). I will think about different content sets.
  • Only 31mm x 41mm size
  • The box has mounting holes from the both sides. So may be I will design additional boards.

Work in progress ;)
