It can wirelessly transmit data to long-distance. It is built-in high-speed and low power-consuming MCU and SX1276 modulation chipset. This chipset is applied with the forward error correction technique which greatly improves interference immunity and advances sensitivity. The coding can detect errors and automatically filter out errors and false data LR-101H provides multi-channels. It supports various settings like baud rate, transmission power, and transmission speed, etc. LR-101H is suitable for long-distance transmission or harsh environments. Product feature  Ultra-high sensitive receiving ability by LoRa spread spectrum modulation technology  Long-distance transmission (1kM)  Support setting various parameters like baud rate, transmission power, and transmission speed  Multi-channel, dual data buffer (each 256 Bytes)  Instant wake up over the air  Four operating modes  Built- in watchdog  PIN connector for easy development and test Hardware Specifications Chipset SEMTECH LoRa SX1276 Antenna RPSMA/50Ω Frequency 903-927 MHz Transmission power 100mW (MAX.) Transmission media UART UART Baud Rate: 1200/2400/4800/9600(Default)/19200/38400/57600bps Parity: 8N1/8E1/8O1 Operation Voltage 3.0V~6V Current consumption Receiving: 13 mA(typical) ， Transmitting: 120 mA(typical) Sleeping: 2.2uA(typical) Transmission distance 1kM(0.81Kbps) Receiving sensitivity [email protected] Operation Temperature -40°C~ 85°C Humidity 5%~95%(Non-condensing) Dimension 30mm x 18mm(PCBA) Connector PIN type, pitch 2.54mm Pin Definition LR-101H Pin Definition Pin Signal name I/O Description 1 GND - Ground 2 VCC - 3.0V~6.0V 3 RXD Input UART input 4 TXD Output UART output 5 BZ Output Module’s operation status 6 P2 Input Pin2 for switching operation mode 7 P1 Input Pin1 for switching operation mode Product Size Operation Mode There are four operating modes of LR-101H. 1. Normal mode 2.Wake-up mode 3.Power-saving mode 4.Setup mode. The four operation modes are switched by the signal level of P1 and P2. Mode 1: Normal mode (P1=0, P2=0) UART is opened. Wireless channel is opened. Penetrating transmission. Mode 2: Wake-up mode (P1=0, P2=1) UART is opened. Wireless channel is opened. The only difference from normal mode is that its preamble is longer than normal mode’s, so that it can make sure the receiver could be waked in the power-saving mode. Note: The receiver could be waked no matter it is in normal mode or wake-up mode or power-saving mode. The receiver would automatically add the RSSI at the end of the received data. Mode 3: Power-saving mode (P1=1, P2=0) UART is closed. The wireless channel is in power-saving mode. You can set up an interval from 0.5 to 5 seconds to wake up in power-saving mode to check if there is preamble. If the receiver receives preamble, it will open UART, and wake MCU to process the received data and return data. After that, it will return to the power-saving mode. Mode 4: Setup mode (P1=1, P2=1) UART is closed. Wireless channel is closed. It could only be configured. Application Note 1. For proper operation of LR-101H, do not leave P1 or P2 floating. Do keep P1 and P2 at fixed level; otherwise it might cause the module instable. 2. Antenna is the important part in the communication system. The quality of antenna would directly influence the communication. Please take the antenna type and antenna’s electrical characteristics into consideration while integrating LR-101 into product.
