Parallax P2 microSD Add-on Board

This adapter provides a convenient way to connect a microSD card to the Parallax Propeller P2 microcontroller, and optionally to any other microcontroller or breadboard project.

The adapter connects a microSD card to any P2 development board with a standard 26 way accessory header. Connecting this accessory to any P2 accessory header allows for general data read/write capabilities (such as data logging or reading program data). Connecting this accessory to the special P2 programming header (IO pins 56-63) would also allow booting from a firmware image stored on the microSD card.

Compatible development systems include the P2 Eval Board Rev C (#64000), and the P2 Edge Module Breadboard (#64020) or P2 Edge Mini Breakout Board (#64019) with a P2 Edge Module (#P2-EC).

The adapter also has seven 0.1 pitch through-hole pads which provide connection to all of the microSD card signals, and accept a standard vertical or right-angle pin header (not supplied) for connection to other microcontrollers or breadboards, such as for the Parallax FLiP try-it kit.

P2 microSD Add-on Board Features

• Connects a microSD card (not included) to the Propeller 2 Accessory Header
• Allows booting from a binary firmware file saved on the microSD card when connected to the P2 programming header (IOs 56-63)
• Connect to any 26 way accessory header for general data reading and writing
• Unpopulated pads allow access to all the microSD card power and control signals, handy for attaching logic probes, or connecting the adapter to a breadboard and/or other microcontroller
