- First prototype
- Add 3.3V onboard reg
- Change AC-DC PSU, add multiple footprints
- Add mounting holes
- Add protection varistors
- 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
- 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
- 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
- Move voltage sense voltage dividers from emonVS to emonTx
- GND > E
- Move to using screw terminals for AC connection due to component shortages :-(
- Tent vias
- Tidy up and bump version for production
- Silkscreen and clearance improvements
- Fix milling
- V1.1 rev2: minor silkscreen and pad size tweaks for production
- Signal and power output connector changed from RJ11 to RJ45.
- 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.
- Renumbered resistor designators to be backwards compatible with older versions.
- Renumbered all component designators to be backwards compatible with older versions.
