[Introduction]:Le module EWM226-900H30S est un module de transmission de données sans fil LoRa à saut de fréquence, conçu pour les tondeuses à gazon. Il offre une puissance d'émission maximale de 30 dBm, plusieurs modes de transmission, fonctionne dans la bande de fréquence 868/915 MHz et dispose d'une sortie de niveau TTL. Il est adapté à des applications telles que les tondeuses à gazon et les systèmes de topographie.


| Pin number | Pin Name | Pin direction | Pin Applications |
| 1 | GND | - | Module ground wire |
| 2 | TXD2 | - | The feet must be suspended in the air. |
| 3 | RXD2 | - | The feet must be suspended in the air. |
| 4 | RESET | input | The module reset pin requires a low-level reset, and the pull-low time must be greater than 100µs. |
| 5 | IO1 | Output | The RXD1 buffer is an empty indicator pin; a high level indicates it is empty, and a low level indicates it is not empty. The size of each serial port data packet cannot exceed 1000 bytes. |
| 6 | IO2 | Output | The master-slave module synchronization indicator pin will output a 1Hz square wave signal after synchronization. |
| 7 | GND | - | Module ground wire |
| 8 | GND | - | Module ground wire |
| 9 | LED_TX | Output | The RF transmit indicator pin outputs a high level when transmitting data and a low level when idle. |
| 10 | LED_RX | Output | The RF receiver indicator pin outputs a high level when receiving data and a low level when idle. |
| 11 | GND | - | Module ground wire |
| 12 | VCC | input | Power supply interface: DC 3.0~3.6V |
| 13 | VCC | input | Power supply interface: DC 3.0~3.6V |
| 14 | GND | - | Module ground wire |
| 15 | GND | - | Module ground wire |
| 16 | GND | - | Module ground wire |
| 17 | SWEDING | - | The feet must be suspended in the air. |
| 18 | SWCLK | - | The feet must be suspended in the air. |
| 19 | CONFIG | input | The mode configuration pin is low to input configuration mode and high to input transmission mode. |
| 20 | 1PPS | input | 1PPS input pin |
| 21 | TXD1 | Output | Serial port output pin |
| 22 | RXD1 | input | Serial input pin |
| 23 | GND | - | Module ground wire |
| 24 | GND | - | Module ground wire |
| 25 | NC | - | The feet must be suspended in the air. |
| 26 | NC | - | The feet must be suspended in the air. |
| 27 | RSV | - | Reserved pins must be left floating. |
| 28 | GND | - | Module ground wire |
| 29 | ON | - | Antenna interface (50 ohms characteristic impedance) |
| 30 | GND | - | Module ground wire |
