[Introduction]:E70-915NW30S est un module de réseau stellaire fonctionnant à 915MHz, basé sur les protocoles Ti cc1310 et 15.4-stack importés à l'origine, avec un coordonnateur et un terminal. Il existe des modes de transmission longue distance, standard et haute vitesse. Jusqu'à 200 noeuds peuvent envoyer des données à un coordonnateur. Utiliser la commande at standard de l'industrie pour fonctionner
| 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 |
