There's one more area where the design is not protected against ESD, the SD/SIM connector.
Against EMI, we have RC filters on the SDIO side and C with implied R on the SIM side. Now, the lack of ESD protection doesn't seem to have caused problems in GTA02, so I'd be reluctant to open another construction site to add ESD protection there. However, I'd like to have a plan B that could be implemented in case of trouble (but only then). That would be to replace the small capacitors (C7501-7510) with TVSs, which also have a small capacitance. Does this sound reasonable ? - Werner _______________________________________________ gta02-core mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/gta02-core
