When and where did you get your copy? The versions I see now at https://store.arduino.cc/usa/arduino-mega-2560-rev3 look updated and current.
can't remember. off the arduino.cc web site, about... 7-8 days ago?
LMV321 ? Seems to be available from several vendors, and on ali-express for cheap. Beware the non-V version, which isn't a rail-to-rail-y.
ah good advice. yeah i just saw the LM321, was going to use that... will make sure it's the LMV321. eagle std libs has the LMV321M5 LMV321M5/NOPB Texas Instruments | Integrated Circuits (ICs) | DigiKey splutter $0.38 in 1k volumes? that's got to have been cloned to be at such low prices on taobao...
ok so added a 12mhz XTAL on the STM32F070 - still cut up about that... LMV321M5 replacing the LM358... nearly there.
