STM32 and LoRa? (photogallery)Print

STMicroelectronics and Semtech released a new development board for IoT (Internet of Things).
The development board is designed for LoRaWAN? network and it supports A and C classes.
The package includes two parts - boards. The first board contains Nucleo-64 development board with STM32L072 microcontroller and the second board contains LoRa? module.
Nucleo-64 STM32L072:
- Cortex? -M0+ core
- 192 Kbytes of Flash
- 20 Kbytes of RAM
- 6 Kbytes of EEPROM
- LCD, crystal-less USB, T-RNG, PCROP ...

LoRa? module:
- 157 dB maximum link budget
- +20 dBm, 100 mW constant RF output versus Vsupply
- +14 dBm high efficiency PA
- Programmable bit rate up to 300 kbps
- High sensitivity: down to -137 dBm
- Bullet-proof front end: IIP3 = -12.5 dBm
- 89 dB blocking immunity
- Low RX current of 10 mA, 200 nA register retention
- Fully integrated synthesizer with a resolution of 61 Hz
- FSK, GFSK, MSK, GMSK, LoRa? and OOK modulations
- Built-in temperature sensor and low battery indicator 1.65 V to 3.6 V power supply

Nucleo-64 development board is supported by IAR, Keil, AC6 System Workbench for STM32 and another.

The price of package is around ?31 ($41).
