Changelog

V0.1

  • First prototype

V0.2

  • Add 3.3V onboard reg
  • Change AC-DC PSU, add multiple footprints
  • Add mounting holes
  • Add protection varistors

V0.3

  • Move C6 to be closer to input of 3.3V vreg
  • Fix silkscreen labels, move all text to TNames
  • Increase footprint size of C5 to case C
  • Fix footprint for input AC connections
  • Fix position of R34 current limiting resistor
  • Increase size of holes for J3

V0.4

  • Reduce TVS MOV to 14mm disk footprint
  • Move J9 and J2 to give more clearance for glands
  • Reduce board size to 77mm x 100mm
  • Fix footprint for MP-LD10-23B05R2 10W PSU
  • Add fiducials, RoHs & OSHW logos

V0.5

  • Increase board size to fit new case
  • Invert voltage sample polarity
  • common-mode choke filter and capacitor
  • Add AC GND connection
  • Increase input connection clearance
  • Add footprint for smaller X2 capacitors

V0.6

  • Move voltage sense voltage dividers from emonVS to emonTx

V0.7

  • GND > E
  • Move to using screw terminals for AC connection due to component shortages :-(
  • Tent vias

V1.0

  • Tidy up and bump version for production
  • Silkscreen and clearance improvements

V1.1

  • Fix milling
  • V1.1 rev2: minor silkscreen and pad size tweaks for production

V1.2

  • Signal and power output connector changed from RJ11 to RJ45.

V1.3

  • General improvements to schematic symbols organization and aesthetics.
  • Phase L1 MOV removed from the output choke (L1) and placed on the input. In this way, protecting the cooke input capacitor and building a classic "common mode surge suppression" topology.

V1.3.1

  • Renumbered resistor designators to be backwards compatible with older versions.

V1.3.2

  • Renumbered all component designators to be backwards compatible with older versions.
