Ebyte SI4463 UART 2Km Range 170MHz 20dBm DIP 21*36mm CE RoHs FCC LoRa Wireless Transmitter RF Module
[Introduction]：E30-170T20D is a 20dBm wireless transceiver module. It operates at 148-173.5MHz, provides an easy way to use& low-power solution for wireless data transmission. Due to the low frequency, the module features strong penetration and diffraction ability. It is highly recommended for the complicated situations with 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 | |
