ABRA Electronics :: Parallax :: Propeller Chips, Kits and Accessories :: 128K Expansion Card

128K Expansion Card

Need more space for your games and applications? The Hydra 128K Memory Expansion Card is just what you need. The card fits into the 20-pin expansion interface on the Hydra and comes with 128K serial EEPROM of non-volatile storage. You can store Hydra programs directly on the card with no special programming, simply insert the card, program the Hydra, and the program is stored on the card's first 32K. Then use the remaining 96K for data and or other application data generated in real-time.

For example, with the proper software you can store 4 different Hydra programs on a single card and then "load" one of the images with a bootloader program or other application that can read the card memory. Additionally, the card has a small "prototype" area on it for thru-hole components that you can add to the card. Enough space to fit a single 8-pin thru hole device and / or extra passive components to add functionality to the card.

Technical Specifications:

Card has a 128Kx8 serial EEPROM with 400KHz access rate, full 20-pin labeled header and power LEDs.
Size: 1x2"
