34 | SOP0 | Hi-Z | – | SOP[2:0] used for factory restore. See Section 9.5. |
35 | nRESET | Hi-Z | I | There is
an internal 100 kΩ pull-up resistor option from
the nRESET pin to VBAT_RESET. Note: VBAT_RESET is
not connected to VBAT1 or VBAT2 within the module.
The following connection schemes are recommended:
|
36 | VBAT_RESET | Hi-Z | – | |
37 | VBAT1 | Hi-Z | – | Power supply for the module, must be connected to battery (2.3 V to 3.6 V) |
38 | GND | N/A | – | Ground |
40 | VBAT2 | Hi-Z | – | Power supply for the module, must be connected to battery (2.3 V to 3.6 V) |
43 | GND | N/A | – | Ground |
44 | UART1_nRTS | Hi-Z | O | UART interface to host (request to send) |
46 | UART1_TX | Hi-Z | O | UART interface to host (transmit) |
47 | UART1_RX | Hi-Z | I | UART interface to host (receive) |
50 | TEST_60 | Hi-Z | O | Connect to external test point. |
51 | UART1_nCTS | Hi-Z | I | UART interface to host (clear to send) |
52 | TEST_62 | Hi-Z | O | Connect to external test point. |
