[Introduction]：E70-915NW30S is the star network module, operating at 915MHz, based on originally imported TI CC1310 and 15.4-Stack protocol, with coordinator and terminal as a whole. There are long range, standard range and high-speed transmission modes. Maximum 200 nodes can send data to one coordinator. Use industry-standard AT commands for operating
| No. | Pin item | Pin direction | Application |
|---|---|---|---|
| 1-3、17、30、31、46、47 | GND | Ground | Ground electrode |
| 4-15、18-21、25、33-35、39-41 | NC | Reserved pin | Reserved, to be floated |
| 16 | LINK | output | For indicating the current network connection status of the module, it can be configured as drain open circuit output or push-pull output. For details, please refer to the parameter setting, a 1K protection resistor shall be connected in series externally (it can be suspended). |
| 22 | TCKC | Input | JTAG TCKC |
| 23 | TMSC | Input | JTAG TMSC |
| 24 | RESET | Input | Module reset pin, low level effective |
| 26 | M0 | Input | M1M0 The four working modes of the module are determined by the joint combination. When in use, a 1K protection resistor shall be connected in seriesexternally, and a 1M pull-up resistor shall be added (it shall not be suspended, otherwise, it can be grounded). |
| 27 | M1 | Input | M1M0 The four working modes of the module are determined by the joint combination. When in use, a 1K protection resistor shall be connected in seriesexternally, and a 1M pull-up resistor shall be added (it shall not be suspended, otherwise, it can be grounded). |
| 28 | VCC | - | Power supply：2.6V ~ 5.5V DC |
| 29 | VCC | - | Power supply ：2.6V ~ 5.5V DC |
| 32 | ACK | Output | The user indicates the data transmission result of the module, which is pulled down before transmission and pulled up after success. It can be configured as drain open circuit output or push-pull output. When it is used, a 1K protection resistor should be connected externally in series (it can be suspended). |
| 36 | RXD | Input | TTL UART inputs, connects to external (MCU, PC) TXD output pin. Can be configured as open-drain or pull-up input. |
| 37 | TXD | Output | TTL UART outputs, connects to external RXD (MCU, PC) input pin. Can be configured as open-drain or push-pull output |
| 38 | AUX | Output | To indicate module ’s working status & wakes up the external MCU. During the procedure of self-check initialization, the pin outputs low level. Can be configured aspush-pull output (suspending is allowed). |
| 42 | PA_EN | Output | Internal single chip microcomputer control PApin, high level effective, connected 45 pin |
| 43 | LNA_EN | Output | Internal single chip microcomputer control LNA pin, high level effective, connected 44 pin |
| 44 | LNA_EN | Input | Internal single chip microcomputer control LNA pin, high level effective, connected 43 pin |
| 45 | PA_EN | Input | Internal single chip microcomputer control PApin, high level effective, connected 42 pin |
| 48 | ANT | - | Antenna 50 ohm impedance |
