What is it?

Makerfabs Maduino Lora Radio (868M) is a main board based on the ATmega328 and RFM98W 868MHz 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 mini current consumption. We use the Arduino pro mini 3.3V 8MHz bootloader in this board and use the CP2104 as USB to serial to upload the code by Arduino IDE.

Spec:

• 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℃
• 168 dB maximum link budget
• +20 dBm - 100 mW constant RF output vs
• +14 dBm high efficiency PA
• Programmable bit rate up to 300 kbps
• High sensitivity: down to -148 dBm
• Bullet-proof front end: IIP3 = -12.5 dBm
• Low RX current of 10.3 mA, 200 nA register retention
• Fully integrated synthesizer with a resolution of 61 Hz
