Maduino Lora Radio 915Mhz - Makerfabs

Maduino Lora Radio is a mainboard based on the ATmega328 and LoRa 915MHz module. The LoRa Radio allows the user to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. We use the Arduino pro mini 3.3V 8MHz bootloader on this board and use the CP2104 as USB to serial to upload the code by Arduino IDE.

Features:
BAT Input Voltage: 3.4-4.2V
ATmega328: 8MHz, 32KB flash, 2KB SRAM
Integrated Power Control System
Interface: I2C/SPI/UART/20*GPIO
Arduino Compatible
Working Temperature: -40 – 85℃
Programmable bit rate up to 300 kbps
127 dB Dynamic Range RSSI
Uses the License-free ISM band: "European ISM" @ 433MHz/868MHz/915MHz
+5 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software)
~100mA Peak during +20dBm transmit, ~30mA during active radio listening
Range of approx. 2Km, depending on obstructions, frequency, antenna, and power output

Package List:
1 x Maduino Lora Radio (915M)
