| 34 | SOP0 | Hi-Z | – | SOP[2:0] used for factory restore. See Section 8.5. |
| 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. |
