[Introduction]:E32-433T33S est un module de port série sans fil (UART) basé sur la solution LoRa de SEMTECH. Il dispose de plusieurs modes de transmission, utilise la technologie à spectre étalé LoRa et fonctionne de 410 MHz à 441 MHz (la valeur par défaut est 433 MHz).
| serial number | pin | Pin direction | Remark |
| 1 | GND | Input | Module ground |
| 2 | VCC | Input | Positive reference of module power supply, voltage range: 3.3~5.5V DC |
| 3 | AUX | output | Used
to indicate the working status of the module; the user wakes up the
external MCU, and the output is low during the initialization of the
power-on self-test Level; (can be suspended) |
| 4 | TXD | output | TTL serial port output, connected to external RXD input pin; |
| 5 | RXD | enter | TTL serial port input, connected to the external TXD output pin; |
| 6 | M1 | Input (very weak pull-up) | Cooperate with M0 to determine the 4 working modes of the module (not floating, if not used, it can be grounded) |
| 7 | M0 | Input (very weak pull-up) | Cooperate with M1 to determine the 4 working modes of the module (not floating, if not used, it can be grounded) |
| 11 | ANT | output | Antenna interface (high frequency signal output, 50 ohm characteristic impedance) |
| 12 | GND | - | Fixedly |
| 13 | GND | - | Fixedly |
| 14 | GND | - | Fixedly |

| 22 | RESET | Input | Module
reset pin, low level trigger, it is recommended that customers use a
single chip microcomputer connection, reset processing and resume work
in unexpected situations |
