Appendix C :: Dimensions 

Figure 21 :: Dimension drawings of the SF02/F

Appendix D :: SF02/F Arduino shield (SF02-AS)

The SF02/F Arduino shield makes it quick and easy to connect the SF02/F to a standard Arduino Uno compatible host controller. All 
the pins for the digital and analog ports are passed through the SF02-AS and can be selectively connected to the Arduino port pins. 
An additional prototyping area with 0.1” pitch holes is also included.
