ATmega328 Board with 868 MHz LoRa
SKU 3085-MADUINOLORA868EAN 8219671107198Item type: AssembledArduino compatible
Description
Maduino is an Arduino-compatible board built around the ATmega328 microcontroller (with the Arduino Pro Mini 3.3V – 8 MHz bootloader) and an on-board LoRa™ RFM95W module at 868 MHz. It uses a CP2104 chip as its USB-to-serial converter, comes with a small external antenna with a UFL connector, and has a reset button plus four jumpers for selecting which digital I/O pins of the RFM95W module (DIO0→D2 / DIO1→D6 / DIO2→D7 / DIO3→D8) are wired to the microcontroller. To program it from the IDE, select the board: ATmega328 (3.3V, 8 MHz)
