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).
