6.5.1 I2C connector reversed?

[ptrauejr]

In looking at the diagrams I see that on 5.5 the I2C connector had the key (open side) facing towards the edge of the board and the sda (green) was on the left. On 6.5.1 I see that the I2C connector had the key facing away from the closest edge of the board yet the SDA was still on the left. Was the connector reversed, or is this an oversight?

I'm upgrading from a 5.6 to 6.5.1 and l just want to make sure I hook this up properly.

For my kit received March 2025: OpenEVSE V6.5:

The I2C connector indeed has the connector key (open side) facing inwards (away) from the board edge. Physically checking the pins with a multimeter, the pinout and orientation is correct for the supplied Adafruit MCP9808 I2C temperature sensor.

Mine works fine as-is.

Note that the label for that connector, as shown on the "Current Version OpenEVSE_PLUS_v6.5.1" photo, shows the label the wrong way round. Note that pin 1 (ground) is at the left as viewed with the connector uppermost.

See the attached photo. Black = pin 1 (ground)

Hope that helps!

My kit also looks like the kit pictured above. I also believe the connector is mislabeled in both png and pdf schematics.
