X-NUCLEO-IDS01A4/5 Hardware description
• The X-NUCLEO-IDS01A4, X-NUCLEO-IDS01A5
are evaluation boards based on the SPIRIT1 RF
modules SPSGRF-868 and SPSGRF-915
• The SPIRIT1 module communicates with the
STM32 Nucleo developer board host
microcontroller though an SPI link available on the
Arduino UNO R3 connector.
