[Introduction]：The E103-W06-TB test board uses a USB interface, which can be used to quickly test the features and functions of the E103-W06 module.
| Pin NO. | Name | Pin direction | Application |
|---|---|---|---|
| 1 | +5V | - | +5V external power supply (not powered by USB) |
| 2 | S1 | - | NC |
| 3 | 3.3V | - | For module power supply selection, connect the power supply jumper cap to the left end (ie 3.3V shorted to 3V3) through the power chip; connect the jumper cap for direct battery power supply to the right end (ie 3.3V shorted to VBAT) |
| 4 | W_LINK | TX | Wi-Fi connection indication, connection: output high, LED off. Disconnected: the output is low and the LED is on. |
| 5 | INDICATE | TX | Module abnormal connection indication, abnormal: output is high, LED is off. Normal: The output is low and the LED is on. |
| 6 | S_LINK | TX | Socket connection indication, connection: output high, LED off. Disconnected: the output is low and the LED is on. |
| 7 | VBAT_RESET | - | Reset enable, connect the jumper cap: reset is pulled up to 3.3V through a 100K resistor. |
| 8 | USB Interface | - | Serial input, output and power supply |
| 9 | VBAT | - | Battery-powered input port, power supply 2.3V~3.6V |
| 10 | RST | RX | Module reset button |
| 11 | SOP2 | RX | Program loading mode selection |
| 12 | SOP1 | RX | Program loading mode selection |
| 13 | SOP0 | RX | Program loading mode selection |
| 14 | TX | TX | Module TX transmission |
| 15 | RX | RX | Module RX receiving |
| 16 | IPX | RX/TX | External radio frequency interface (external antenna requires jumper resistance) |
| 17 | E103-W06 | - | E103-W06 module |
