HOME / PRODUCTS / RF MODULE / ST-RF-LORA-STM32W
The new ST-RF-LORA-STM32W is based on Sub-GHz Wireless Microcontrollers. Arm Cortex-M4 @48 MHz with 256 Kbytes of Flash memory, 64 Kbytes of SRAM. LoRa, (G)FSK, (G)MSK, BPSK modulations. AES 256-bit. Multiprotocol System-on-Chip.
This module is designed to be extremely low-power and are based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 48 MHz. This core implements a full set of DSP instructions and an independent memory protection unit (MPU) that enhances the application security.
The operating temperature/voltage ranges are –40 °C to +105 °C and a comprehensive set of power-saving modes allows the design of low-power applications. Size of the module was reduced to fit to many IOT application, an external antenna connector has been added to extend wireless range.
