Maduino LoRa is a board based on the ATmega328 microcontroller (with bootloader Arduino pro mini 3,3V – 8 MHz) and module LoRa™ RFM98W a 433 MHz. It use the CP2104 as USB to serial converter to upload the code by Arduino iDE. It has a reset button and four jumpers to select I/O digital pins of module RFM98W (DIO0→D2 / DIO1→D6 / DIO2→D7 / DIO3→D8) that can be to connect to microcontroller. Programming via IDE occurs by selecting the tab: ATmega328 (3.3V, 8 MHz). Maduino allows to send data and reach extremely long ranges at low data-rates. It is particularly suitable for use in remote controls, smart meters, Home Automation, personal loggers, wireless sensor network, wireless PC peripherals, etc.
