KYOCERA AVX's LoRa Module ETH-LORA-M-AX-01 is an SMT
mounted cost efficient and low power radio module that operates in theunlicensed 868/915 MHz bands. It combines a LoRa™ transceiver SX1272
of Semtech Corporation [1] with Ethertronics chipset and technologies
to maximize the link budget and RF performance. A sensitivity of up
to -138 dBm and a maximum output power of +19 dBm results in a linkbudget of more than 156 dB. The increase in the link budget results inmuch longer range and robustness without the need for additional components.

Real-World Performance and Implementation
Designed for global market, pre-certified KYOCERA AVX's ETH-LORA-M-AX-01
helps reducing time consuming for radio development and related costs.
Compared to other available modules in the market, ETH-LORA-M-AX-01 is
embedded with proprietary Impedance Matching and Active Steering™
capabilities to optimize the RF performance on its own in order to achieve an
excellent ultra-long range spread spectrum communication.
ETH-LORA-M-AX-01 is designed with power saving techniques so that thecurrent consumption is low even when in communication.

16 MHz* UART interface is available now. SPI and I2C are coming soon with Firmware Update

For the current firmware version, ETH-LORA-M-AX-01 supports UART to interface with the host using AT
commands. The UART interface consists of only two lines RXD (input) and TXD (output) thus simplify theconnection with the host. To save power consumption, this module support low power mode: Deep Sleep andStop. In deep sleep mode, the module can wake up from UART command, while in stop mode the wake-up pin(P11) must be connected to the RX line of this module on the user’s PCB, so that the character sent by user
can wake up the module. Please refer to document about the integration guideline [2] and at command [3] formore details.
