19 GPIO28 I/O 18 General IO port
20 NC I/O - No pins connected, users don’t need to care
21 JTAG_TCK I/O 19 JTAG emulation pin, JTAG TCK input; if not used, no connection is required; the module has a built-in 100K pull-down resistor.
22 JTAG_TMS I/O 20 JTAG emulation pin, JTAG TMS input; don’t connect if not used.
23 SOP2 - 21 The SOP2 pin has a built-in 100K pull-down resistor; when in use, an external pull-up resistor 10K is required to pull the pin level high.
24 SOP1 - 34 The SOP1 pin has a built-in 100K pull-down resistor; when in use, an external pull-up resistor 10K is required to pull the pin level high
25 GND - - Ground wire, connected to the power reference ground
26 GND - - Ground wire, connected to the power reference ground
27 GND - - Ground wire, connected to the power reference ground
28 GND - - Ground wire, connected to the power reference ground

34 SOP0 - 35 The SOP0 pin has a built-in 100K pull-down resistor; when in use, an external pull-up resistor 10K is required to pull the pin level high.
35 nRESET I 32 35rd and 36rd,the same
36 VBAT_RESET - - The nRESET pin has a built-in 100K pull-up resistor to the VBAT_RESET pin. Note: VBAT_RESET is not connected to VBAT1 or VBAT2 inside the module.The following connection methods are recommended:1.Only when nRESET will be in a defined state under all operating conditions, connect nRESET to a switch, external controller, or host.Keep VBAT_RESET unconnected at this time to save power.2.If nRESET cannot be in a defined state under all operating conditions,VBAT RESET must be connected to the main power supply (VBAT1 and VBAT2) of the module. Due to the internal pull-up resistor, the leakage current is expected to be (3.3 V/ 100 kΩ) mA.
37 VBAT1 Power 37,39 The module power supply is positive reference, the voltage range is 2.3 V to 3.6 V. Note: The module is not internally connected to VBAT2, so it needs to be short-connected to Pin 40 VBAT2 when in use; see the recommended connection diagram in Chapter 4 for details.
38 GND - - Ground wire, connected to the power reference ground
39 NC - - No pins connected, users don’t need to care
40 VBAT2 Power 10,44,54 The module power supply is positive reference, the voltage range is 2.3 V to 3.6 V. Note: The module is not internally connected to VBAT1, so it needs to be short-connected to Pin 37 VBAT1 when in use; see the recommended connection diagram in Chapter 4 for details.
