After the trouble with the breakout board, some fixes were found. Attaching pull-up resistors to the RST, SDA, and SCK pins helped considerably. The signal was still not entirely reliable but reinitializing the pins as inputs with pinMode() alleviated a lot of the problems. The solderless breadboard may have unreliable power terminals which could be the source of some of the unreliability.

A DIP chip was installed on the breadboard to test the fixes on another chip and they worked well. With the chip on the board, it was also possible to change the address to check the undocumented addressability of the library.
