X-NUCLEO-STMODA1 Data brief STMod+ connector expansion board for STM32 Nucleo Features STMod+ connector compatible with STM32 Nucleo boards Full STMod+ support for a range of interfaces: SPI, UART, IC, RESET, INTERRUPT, ADC, PWM and general purpose I/Os STM32 Nucleo support through Arduino UNO V3 connector Set of 15 Jumpers to allow multiple configurations and expand the range of possible use cases RoHS compliant Description The X-NUCLEO-STMODA1 provides an easy way to expand your STM32 Nucleo board with the STMod+ connector, which allows interaction with the new set of STM32 Nucleo development boards using this connector. It provides an easy way to evaluate the STMod+ board solution together with other STM32 Nucleo boards. The STMod+ is a 2x10-pin connector providing a set of interfaces such as SPI, UART, IC and other functions such as RESET, INTERRUPT, ADC, PWM and general purpose I/Os. The X-NUCLEO-STMODA1 has a female STMod+ connector with 2 mm pitch. The X-NUCLEO-STMODA1 expansion board is equipped with a set of jumpers for the added flexibility of allowing you to also use the board with the STM32 B-L475E- IOT01A discovery kit node board.
