[pacsat-dev] MRAM

At Thursday night's meeting Chris brought up having more MRAM on future boards.

The daughter board uses four smaller capacity chips due to the number required for the six boards created.

The MRAM chips on the current board can be replaced but it will have to be done using a heat gun due to the pin characteristics of the chips.

We could do some board swapping as no spares exist and I can replace the modules and test this time as we have capable software.

One meg (128x8) regular chips (non-automotive/flight) cost approximately $10 each and four meg (512kx8) are approximately $21 each in single lots.

Discounts start at purchases of 10 but are not that substantial.
