Notes:
1.  The module signal grounds are isolated from the module case.
2.  This is an open collector/drain output that on the host board requires a 4.7 kΩ to 10 kΩ pullup resistor to VccHost. See Figure 2.
3.  This input is internally biased high with a 4.7 kΩ to 10 kΩ pullup resistor to VccT.
4.  Two-Wire Serial interface clock and data lines require an external pullup resistor dependent on the capacitance load.
5.  This is a ground return that on the host board requires a 4.7 kΩ to 10 kΩ pullup resistor to VccHost.
