X-NUCLEO-IDS01A4
Sub-1 GHz RF expansion board based on the SPSGRF-868
module for STM32 Nucleo
Data brief
Description
The X-NUCLEO-IDS01A4 is an evaluation board
based on the SPIRIT1 RF module SPSGRF-868
expansion of STM32 Nucleo boards. The
SPSGRF-868 module operates in the 868 MHz
ISM band and is ETSI certified. Identification of
the operating frequency of the X-NUCLEOIDS01Ax (x=4 or 5) is performed through two
resistors (R14 and R15). It is compatible with the
MORPHO and Arduino UNO R3 connector
layout. The X-NUCLEO-IDS01A4 interfaces with
the STM32 microcontroller via SPI connections
and GPIO pins. The user can change some of
the GPIOs by mounting or removing the resistors.
