Description:

This is a Mysensors serial GW using RFM69W radio module and ATSAMD21E 32 bit MCU

Key features:

  • ATSHA204A for signing
  • MySensors ready(ATSAMD21E + RFM69W)

Work progress:

  1. Test/verify the pcb board correctness(from both electrical and mechanical point of views) - DONE
  2. Produce the initial PCB's using some external PCB manufacturer - IN PROGRESS
  3. Components assembly(soldering)
  4. Upload Mysensors serial GW sketch code
  5. Verify the real board with running code
  6. Create project enclosure using a 3D printer

HW Revisions:

  • 0.1 - initial design
  • 0.2 - added I2C EEPROM and VUSB filtering caps
  • 0.3 - added USB lines termination resistors
  • 0.4 - added I2C EEPROM pull-up resistors
