[Introduction]：E180-ZG120B is a small, low-power, high-reliability, 2.4GHz ZIGBEE module based on Silicon Labs EFR32MG1B. The chip comes with high-performance 32-bit ARM Cortex. -M4 core, integrated internal power amplifier, transmit power up to 20dBm.
| Pin No. | Pin item | Pindirection | Application |
|---|---|---|---|
| 1 | ANT | Input /Output | Externally connected with stamp hole |
| 2 | GND | - | Ground, connecting to power source referential ground |
| 3 | PD13 | Input | TOUCHLINK pin to be continuously pulled lower than 3000ms and it will initiate a ZLL network or join request |
| 4 | PD14 | Input | The WAKE pin is mainly used to wake up the sleeping terminal. It is high level when power is on. When the pin is pulled low externally, the sleeping terminal device will be woken up. |
| 5 | PA0(TX) | Output | UART TX pin |
| 6 | PA1(RX) | Input | UART RX pin |
| 7 | NC | - | - |
| 8 | NC | - | - |
| 9 | PD15 | Input | Working mode switching pin. When the pull-down time is longer than 500ms,the working mode is switched. |
| 10 | PB11 | Input | The UART_BAUD_RESET pin is used to reset the device baud rate. The power-on default is high. In any mode, if this pin is pulled lower for more than 1000ms, the serial port parameters of the module will be restored to the default 115200. |
| 11 | PB12 | Output | The ACK pin is used to indicate the last user data transmission status. This pin is pulled low before the transmission is started, and the pin is pulled high after the transmission is successful. |
| 12 | PB13(GPIO0) | Input /Output | GPIO input/output port 0 |
| 13 | VCC | - | - |
| 14 | GND | - | - |
| 15 | NC | - | - |
| 16 | NC | - | - |
| 17 | NC | - | - |
| 18 | PC10 | Output | AUX pin indicates the current working state of the device. When the pin is low, |
| 19 | PF2(GPIO2) | Input /Output | GPIO input/output port 2 |
| 20 | NC | - | - |
| 21 | PC11(ADC1) | Input | ADC Detection port 1 |
| 22 | NC | - | - |
| 23 | NC | - | - |
| 24 | NC | - | - |
| 25 | SWCLK | Input /Output | DBG_SWCLKTCK |
| 26 | SWDIO | Input /Output | DBG_SWDIOTMS |
| 27 | PB14(PWM0) | Output | PWM output port 0 |
| 28 | PB15(PWM2) | Output | PWM output port 2 |
| 29 | NC | Output | LINK pin shows current network state, high level means access to network |
| 30 | PF3 | Output | - |
| 31 | NC | - | - |
| 32 | NC | - | - |
| 33 | NC | - | - |
| 34 | NC | - | - |
| 35 | NC | - | - |
| 36 | GND | Input /Output | Ground |
| 37 | nRESET | Input | Reset |
