Cumulus New PCBs Ordered
Posted by retromaster on December 21, 2010
A small update this time. I’ve finished the new Cumulus PCB design (revision B) and just yesterday ordered a few units from a manufacturer in China. Usually I manufacture my own prototypes before ordering from a manufacturer, but this time I did not do that, mainly to save some time. Hopefully there are no (major) problems/mistakes with the design :).
Here is a quick summary of what’s new: Integrated LCD and buttons, 40-pin connector (for use with CumuluBus), better routing on critical lines (to further avoid crosstalk), elimination of 74221-based circuitry and crystal oscillator for driving the PIC and the CPLD.
