AT24C02C-STUM-T
Public Made by Adomby adom
Microchip EEPROM, SOT-23-5. Pinout extracted from the datasheet, KiCad symbol/footprint/3D.
← Commit history
symbol: the part is a 5-lead SOT-23 - the shipped footprint has 5 pads and the datasheet confirms it for this ordering suffix - but the symbol carried the 8-pin SOIC pinout. Pinout taken from this part's datasheet for its own ordering suffix. The library failed validate because the symbol declared pins the footprint has no pad for (connect-pad-unresolved), which also blocked its orderable attributes. Rebuilds the .lbr, re-derives pin 1 and pads.json.
