eeprom for HATS - find a supplier

Wed May 13, 2015 8:16 pm

Hello,

I'm trying to find a UK supplier of eeproms suitable for the HAT specification, in small quantities,
just an assortment to play with. I'm not sure what the specifications mean when I read the data sheets.
I would appreciate some help.

Regards
