APPLICATION INFORMATION

2.1

Reference Schematics

Figure 2-1 through Figure 2-4 illustrate the BM70/71

reference circuits for various Stock Keeping Units

(SKUs). The GPIOs are configurable and the connec-

tion depends on the user’s application circuit.

The power input range is 1.9V~3.6V. If the battery is

used, the battery reverse protection circuit is

recommended. The VDD_IO voltage is same as power

input. If the LED is used, ensure that the voltage is

more than 3V to drive the LED. A 1.8V Reset IC is

added as an optional circuit to prevent the Flash data

crash when VBAT power is unstable. It is recommended

to implement the RF antenna matching circuit as

illustrated in Figure 2-3 and Figure 2-5 to fine tune the

antenna impedance matching.
