Note1: Module ground pins GND are isolated from the module case.

Note2:  ModSelL  is  an  input  signal.  When  held  low  by  the  host,  the  module  responds  to  two-wire  serial communication commands. The ModSelL signal allows the use of multiple modules on a single two-wire interface. When ModSelL is high, the module shall not respond to or acknowledge any two-wire interface communication from the host.

Note3: Shall be pulled up with 4.7K-10Kohms to a voltage between 3.15V and 3.45V on the host board.
