[Introduction]：E70-915NW14S 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.

| 17 | 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 series externally, and a 1M pull-up resistor shall be added (it shall not be suspended, otherwise, it can be grounded). |
| 18 | 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 series externally, and a 1M pull-up resistor shall be added (it shall not be suspended, otherwise, it can be grounded). |
| 19 | RXD | Input | TTL UART inputs, connects to external TXD output pin. Can be configured as open-drain or pull-up input. For details, please refer to parameter setting. |
| 20 | TXD | Output | TTL UART outputs, connects to external RXD input pin. Can be configured as open-drain or push-pull output. For details, please refer to parameter setting. |
| 21 | TMSC | Input | JTAG TMSC |
| 22 | TCKC | Input | JTAG TCKC |
| 25 | 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 as open-drain output or push-pull output, see parameter settings for details. A 1K protection resistor needs to be connected in series when using(it can be suspended) |
| 26 | VCC | - | Module power supply positive reference, voltage range: 2.2V ~ 3.8V DC |
| 28 | 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). |
| 32 | RESET | Input | Module reset pin |
| 35 | LINK | Output | To indicate module ’s current network connection status. Can be configured as open-drain output or push-pull output, see parameter settings for details. A 1K protection resistor needs to be connected in series when using. (it can be suspended) |
