> [@abbyanastasia](#): > > In regards to holes for mounting, I want to put holes to mount the PCB, but you said they are outside of the PCB area. Can you further explain? Looks like I screwed up and moved the mounting holes outside the board path when I changed something, as the mounting holes are in the correct place in your original sketch so disregard that part of the post. The need for a I2C level translator still exists however as the Arduino WiFi Rev 2 operates at 5V and the sensor is at 3.3V. It will probably work as it stands, but it is straining the sensor by applying 5V to a 3.3V input and may eventually cause it to fail. > [@abbyanastasia](#): > > Lastly, I am using an Arduino WiFi Rev 2 board, which has SCL and SDA on the other side instead of configuring A4 and A5 as SCL and SDA for Arduino Rev 3. Should my SCL and SDA be routed to the other side then? Then you should swap in the Arduino WiFi Rev 2 from this post (which I just updated to be correct which it wasn’t.) Here the SCL/SDA lines are uncoupled from A4/A5 so they will route to the correct pins. If you delete the Uno with delete minus (rather than delete) Fritzing will leave the traces in place when deleting the part. You then need to drag the end of the traces to remake the connections after placing the Arduino WiFi Rev 2. > [@Request - Arduino uno wifi Rev2](https://forum.fritzing.org/t/request-arduino-uno-wifi-rev2/7590/2): > > As far as I can see from the Fritzing point of view this is identical to the current Uno part. Are there new connectors that I am not seeing? The only thing Fritzing cares about are physical connections, the wifi and the new IMU are invisible in Fritzing. At most it may need a change in label on breadboard which is pretty trivial. Edit: I see it needs to have the second isc connector removed too, I will post a modified part in a bit.
