Connect Hardware

The hardware connections are simplified using the available hardware from Microchip and Mikroe. The PIC24FJ256GA7 Curiosity Development Board supports the microSD board but not the MCP2221A Breakout Module. Jumpers will be used to connect the PIC24FJ256GA7 Curiosity Development Board to the MCP2221A Breakout Module. We will cover the required hardware connections. 

Attach microSD Click board

Attach the microSD Click board™ into the mikroBUS™ A Interface of the PIC24FJ256GA7 Curiosity Development Board.

Do not insert the microSD card at this time.
