[Introduction]:E30-170T20D est un module d'émetteur-récepteur sans fil de 20 dbm. Il fonctionne à 148-173,5 MHz, fournit un moyen facile d'utiliser et une solution de faible puissance pour la transmission de données sans fil. En raison de la basse fréquence, le module présente une forte capacité de pénétration et de diffraction. Il est fortement recommandé pour les situations compliquées avec des obstacles.
Pin No. | Pin Item | Pin Direction | Pin Application | |
---|---|---|---|---|
1 | M0 | Input(weak pull-up) | Work with M1 & decide the four operating modes. Floating is not allowed, can be ground. | |
2 | M1 | Input(weak pull-up) | Work with M0 & decide the four operating modes. Floating is not allowed, can be ground. | |
3 | RXD | Input | TTL UART inputs, connects to external TXD (MCU, PC) output pin.Can be configured as open-drain or pull-up input | |
4 | TXD | Output | TTL UART outputs, connects to external RXD (MCU, PC) input pin.Can be configured as open-drain or push-pulloutput | |
5 | 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 as open-drain output or push-pull output (floating is allowed). | |
6 | VCC | Input | Power supply 2.3V-5.5V DC | |
7 | GND | Input | Ground | |
