Release Notes

OMHEY_4_2

  • R59 is a ferrite bead
  • silkscreen of C59 and R69 are swapped
  • The wires that go to the connectors for the currentsensor are on the top and are to visible through the silkscreen, they are moved to the bottom layer.
  • The name OMHPR is eliminated
  • Use double footprint for voltage transformers (also other version can be used)
  • known issues:
    • phase L3 is not working -> shortcircuit, patch or new version needed
    • 220E on the secondary of the voltage transformators is to high for type WPT102
  • known upgrades:
    • change power DC/DC converter to onpcb version
    • J7 should be DNP, and changed to an 6 pin debug connector with rx and tx.
    • VBUSON is on a used pin for DO2_1
    • 2x3pin connector is much cheaper than 3x2pin for 230VAC

OMHEY_4_1

  • if only 1 phase is needed you only need one voltage transformer. This can be achieved with 0E resistors.
  • miso and mosi were not connected for the 2 toppanel connectors.
  • known issues:
    • R59 should be a ferrite bead
    • silkscreen of C59 and R69 are swapped
    • The wires that go to the connectors for the currentsensor are on the top and are to visible through the silkscreen, they should be moved to the bottom or inner layer.
    • The name OMHPR is still used
  • known upgrades:
    • change power DC/DC converter to onpcb version
    • Use double footprint for voltage transformers

OMHEY_4_0

  • 6T version
  • 3 phase voltage measurement
  • 12 current measurement
  • New Phoenix connectors
  • Program connector reachable from the outside with debug uart on pin 6.
