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.
- MCU – Microchip Atmel SAMD21 32-bit ARM Cortex M0+ MCU @ 48 MHz with 32 KB SRAM, 256 KB flash (8KB for bootloader)
- External Storage – 2MB SPI flash
- Digital I/O Pins – 8x digital I/Os, 12x PWM, UART, SPI, and I2C, 8x external interrupts
- Analog Pins – 7x analog inputs (8/10/12-bit ADC), and 1x analog output (10-bit DAC)
- DC Current per I/O Pin – 7 mA
- LPWAN connectivity
- Murata CMWZ1ZZABZ LoRa module based on Semtech SX1276 and STMicro STM32L
- Antenna power – 2dB
- Carrier frequency – 433/868/915 MHz
- Working regions – EU/US
- USB – 1x micro USB port for power and programming
- Security – ATECC508 secure element (ECC508 crypto chip)
- Misc – Reset button, 6x LEDs, 32.768 kHz RTC
- 5V via micro USB port or VIN pin
- 2-pin header for rechargeable Li-ion or Li-Po battery
- I/O Operating Voltage – 3.3V
- Power Consumption – As low as 104uA
- Dimensions – 67.64 x 25 mm
- Weight – 32 grams
The board can connect to Arduino Create, your own LoRa network using the Arduino Pro Gateway for LoRa, an existing LoRaWAN infrastructure like The Things Network, or other boards using P2P connectivity. You can read the getting started guide to find out how to use the board.
Arduino MKR WAN 1310 board is sold for $37.95 excluding taxes and shipping.
