How to Use I2C EEPROM with Arduino
https://www.electronics-lab.com/how-to-use-i2c-eeprom-with-arduino/
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 […]

Samsung Electronics introduced the 108 megapixel (Mp) Samsung ISOCELL Bright HMX, the first mobile image sensor in the industry to go beyond 100 million pixels. With the latest addition, Samsung will expand its 0.8μm image sensor offerings from its recently announced ultra-high 64Mp to 108Mp, a resolution equivalent to that of a high-end DSLR camera. […]
PSRR of low dropout voltage regulators
https://www.electronics-lab.com/psrr-low-dropout-voltage-regulators/
Here’s an app note about PSRR of LDO from Microchip. The Power Supply Rejection Ratio is the ability of a device, such as a Low Dropout Voltage regulator, to reject the various perturbations that can be found in its input supply rail by providing a greatly attenuated signal at the output. Generally, the main source […]
