3.5 Jumpers

There are 12 jumpers (J1, J2, J3, J10, JP6, JP7, JP8, JP10, JP12, JP13 and JP14) available on the BM71 EVB. The following tables provide the details of the pins and signals that are associated with the jumpers.
Table 3-1. Power Source Option Connector
Part NumberPinSignalDescription
J11PIC_3V3Power source from PICtail™ 3.3V, enabled by pin 2 in the jumper bank J1
2VBATBM71 power source input
3USB_3V3Power source from USB enabled by pin 4 on the jumper bank J1. 5V USB power sends the power input to 3.3V LDO to provide the module with a 3.3V input
4VBATBM71 power source input
5BATPower source from coin cell battery (SK1) enabled by pin 6 on the jumper bank J1
