Two year ago Arduino launched MKR WAN 1300 board powered by Arduino Zero compatible Microchip Atmel SAMD21 32-bit ARM Cortex M0+ MCU and a Murata CMWZ1ZZABZ LoRa module based on Semtech SX1276 and STMicro STM32L microcontroller.
The company has now announced a new improved LoRa board – MKR WAN 1310 – with lower power consumption thanks to a new battery charger , a 2MB SPI flash which enables data logging and other OTA (Over-the-Air) functions, and a crypto chip that can securely store credentials and certificates.
