Hardware description - STEVAL-IDI001V1-Exp
STEVAL-IDI001V1-Exp is an expansion board that allows the interoperability between
STEVAL-IDI001V1, STM32-Nucleo and X-NUCLEO expansions. Expansion boards can be
connected either via Arduino or Morpho connectors. The hardware is compatible with
STM32-Nucleo and it is possible to use the STEVAL-IDI001V1 as a sensor-Hub by
connecting an STM32-Nucleo to the STEVAL-IDI001V1-Exp. The STEVAL-IDI001V1-Exp
is equipped with Morpho connectors (upward and downward) and Arduino UNO R3
connectors (upward) to accommodate multiple boards. It is also equipped with STEVAL-
IDI001V1 connectors. Three different power supply options are available: STM32-Nucleo (if
plugged), STEVAL-IDI001V1 USB or an external 5 V power supply.
