[Introduction]：E49-400T30S est un module de transmission de données sans fil rentable introduit par Chengdu ebyte. Il existe quatre modes de fonctionnement. Chaque méthode de transmission a ses propres caractéristiques et peut être appliquée à divers scénarios d'application. Le e49 - 400t30s supporte parfaitement les applications de qualité industrielle et est soumis à des essais rigoureux en usine pour assurer sa fiabilité industrielle et la conformité des lots.
| Pin number | Pin name | Pin Orientation | Pin Usage |
|---|---|---|---|
| 1 | GND | Input | Module ground |
| 2 | VCC | Input | DC Module power positive reference, voltage range: 3.3 ~ 5.5V DC |
| 3 | AUX | Output | Used to indicate the working state of the module; the user wakes up the external MCU, and outputs a low level during the power-on self-test initialization; (can be left floating) |
| 4 | TXD | Output | TTL serial output, connected to external RXD input pin; |
| 5 | RXD | Input | 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 (can not be suspended, 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 (can not be suspended, 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 |
| 18~20 | NC | Input/Output | NC pin, this pin needs to be left floating (for subsequent expansion) |
| 21 | NC | Input | download port --VCC (Hanging, users do not need to pay attention) |
| 22 | NC | Input | download port –SWDIO (Hanging, users do not need to pay attention) |
| 23 | GND | Input | download port --GND (Hanging, users do not need to pay attention) |
| 24 | NC | Input | download port --SWCLK (Hanging, users do not need to pay attention) |
