This module is a cost efficient and convenient way to make use of Arduino UNO shield in combination with an Arduino NANO development board.
The NANO module will be placed in the socket on the adapter board.
The expansion module comes with an on-board 3.3V voltage regulator with max. 1A output current, enough to supply many 3.3V sensors and accessories with power.
The stackable “Arduino headers” shown on the last picture in the gallery are not included in the kit, but we have a set of those headers available in the store.
