Expand your board’s storage with an I2C-enabled EEPROM chip. EEPROM stands for Electronically Erasable Programmable Read-Only Memory. It allows for values to be written and stored for long periods of time while using very little power. Most microcontrollers even have EEPROM directly in their circuitry, such as the ATmega328P (Arduino Uno chip), which has 1KB […]
