IoTaaP Expander
IoTaaP Expander enables you to use four modules at the same time. Expander can be powered by external PSU or from main board.
Expand your possibilities
IoTaaP Expander has an onboard voltage regulator that will provide stabile 3.3V for your modules thanks to AP2114H-3.3TRG1 LDO regulator. The expander can be powered by external 5V power supply and by selecting jumper configuration it can be used to power your development board, but also to be powered by a development board. Selection depends on the number and type of the shields that are going to be used on the expander board.
Schematic
Pinout
IoTaaP expander replicates IoTaaP Embedded pinout four times. You will find male headers on the bottom side used to connect the module to the main development board.
