GBA 32MB Development Flash Cart

$4.00$18.00

A development flash cart for the GBA which allows for 32MB (x2 if you can toggle the A24 pin on the flash chip). Just putting this out there in case any developers are interested in it, you never know.

This flash cart is only intended to be used for developers seeking to play around with CPLDs who just want a GBA board to get started with which is why the board finish is HASL. There are 7 pins broken out on the CPLD which can be used for anything you like – perhaps you would like to write to a certain address and have one of those pins toggled or you could use those pins to bit bang I2C, SPI, etc and communicate with any device you like.

We won’t be able to offer support for this board so you’ll need to know what you’re doing. If you purchase the pre-programmed option, the CPLD will be pre-programmed so the flash cart will be ready to be flashed up to 32MB.
