MS23SF1-4YE5AIR
Overview
The MS23SF1-4YE5AIR is a high-performance LoRaWAN transceiver module featuring an integrated Arm Cortex-M4 core running at 48MHz. Designed for long-range communication in the 868MHz and 915MHz ISM bands, it provides a programmable bit rate and 24 GPIOs for complex sensor interfacing.
Why Choose This Part
This module combines a powerful Arm Cortex-M4 microcontroller with 256KB Flash and 64KB RAM, allowing it to handle both communication stacks and local application logic. The 120mA run current during transmission and 4.2uA quiescent current profile make it suitable for battery-operated LPWAN endpoints.
Applications
Getting Started
Development typically involves using the Arm Keil MDK or GCC toolchain to program the onboard Cortex-M4 MCU. An external antenna is required for operation, which should be matched to the 868MHz or 915MHz operating frequency. Use the 24 available GPIOs to interface with digital sensors via UART, SPI, or I2C.
