      Connector jp4 has the labels for scl and sda reversed on my board, V 0.4. Electrical connectivity is reversed from the labels on the nearby bar of connectors and from the labels on the schematic.

      Good find! It’s only the printing on the PC board that is backwards — the actual pin traces follow the standard Grove I2C Pinout: SCL-SDA-Vcc-Gnd (as shown on the schematic). So this shouldn’t be a problem for anyone using a standard Grove cable with connectors on both ends, but if you use one with flying leads or are hacking together your own cable, then the misprint could cause some confusion. I’ll be sure to update the v0.3 and v0.4 board documentation to include a note about the misprint. Thanks!

      Yup, hacking together my own cable is how I found it.
