[Introduction]:Le module de transmission de données sans fil EWT226-900H30S est un kit de test conçu par EBT, basé sur le module LoRa pour tondeuses à gazon EWM226-900H30S. Il intègre une puce CH340X haute performance, réduisant considérablement le cycle de développement. Pour plus d'informations sur l'EWM226-900H30S, veuillez consulter le site web officiel afin de télécharger la documentation relative à ce modèle.


| Serial Number | definition | illustrate | Remark |
| 1 | Type-C | DC 5.0V power supply and communication interface | Standard Type-C interface, plug and play. |
| 2 | VCC | Module VCC power supply jumper | Default power supply: DC 3.3V |
| 3 | PWR | Power indicator light | Power supply is normal, indicator light is constantly on. |
| 4 | RX | Serial port receiver indicator light | The indicator light flashes when receiving data via serial port. |
| 5 | TX | Serial port transmit indicator light | The indicator light flashes when the serial port is transmitting. |
| 6 | IO1 | RXD1 buffer status indicator | The RXD1 buffer is indicated by an indicator light; a lit light means it is not empty, and an off light means it is empty. The size of each serial port data packet cannot exceed 1000 bytes. |
| 7 | RESET | Reset button | - |
| 8 | IPEX | IPEX1 antenna interface | - |
| 9 | Senior High School | SMA-K antenna interface | - |

| Pin number | Pin Name | Pin direction | describe |
| 1 | TXD2 | - | The feet must be suspended in the air. |
| 2 | RXD2 | - | The feet must be suspended in the air. |
| 3 | NRST | input | The module reset pin is triggered by a low level, and the pull-low time must be greater than 100µs. |
| 4 | IO1 | Output | The RXD1 buffer is an empty indicator pin; a high level indicates an empty buffer, and a low level indicates a non-empty buffer. The size of each serial port data packet cannot exceed 1000 bytes. |
| 5 | IO2 | Output | The master-slave module synchronization indicator pin will output a 1Hz square wave signal after synchronization. |
| 6 | LED_TX | Output | The serial port transmit indicator pin outputs a high level when transmitting data and a low level when idle. |
| 7 | LED_RX | Output | The serial port receive indicator pin outputs a high level when receiving data and a low level when idle. |
| 8~10 | VCC | input | Module power supply interface, DC 3.0~3.6V |
| 11~13 | GND | - | power ground |
| 14 | SWEDING | - | The feet must be suspended in the air. |
| 15 | SWCLK | - | The feet must be suspended in the air. |
| 16 | GND | - | power ground |
| 17 | CONFIG | input | The mode configuration pin is low to input configuration mode and high to input data transmission mode. |
| 18 | 1PPS | input | 1PPS input pin |
| 19 | TXD1 | Output | Serial port output pin |
| 20 | RXD1 | input | Serial input pin |
| 21 | IO3 | - | The feet must be suspended in the air. |
| 22 | IO4 | - | The feet must be suspended in the air. |
| 23 | RSV | - | The feet must be suspended in the air. |
| 24 | GND | - | power ground |
