TCA9548A 1-to-8 I2C Multiplexer ₹ 239.99 ₹ 435.00
You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize "Uh oh, this chip has a fixed I2C address, and from what I know about I2C, you cannot have two devices with the same address on the same SDA/SCL pins!" Are you out of luck? You would be, if you didn't have this ultra-cool TCA9548A 1-to-8 I2C multiplexer! Finally, a way to get up to 8 same-address I2C devices hooked up to one microcontroller - this multiplexer acts as a gatekeeper, shuttling the commands to the selected set of I2C pins with your command. Using it is fairly straight-forward: the multiplexer itself is on I2C address 0x70 (but can be adjusted from 0x70 to 0x77) and you simply write a single byte with the desired multiplexed output number to that port, and bam - any future I2C packets will get sent to that port. In theory, you could have 8 of these multiplexers on each of 0x70-0x77 addresses in order to control 64 of the same-I2C-addressed-part. Some header is required and once soldered in you can plug it into a solderless-breadboard. The chip itself is 3V and 5V compliant so you can use it with any logic level.

This is a programmer expansion shield that allows your for Arduino board to modify the fuse bits and burn bootloader into external chip and other for Arduino boards.  On-board buzzer and LED indicators, indicating whether the burning is successful, it is convenient for Arduino board designers to batch burning. Feature:  Compatibility: As it uses SPI pins of ICSP interface, compatible with for Arduino UNO R3 / for Arduino Mega2560, can change to the bootloader burner when it is directly plugged onto the two boards.  Operating voltage: 5V  Operating current: 500mA (max)  On-board buzzer, if the fuse bit is successfully modified, it will sound once, and then if burning bootloader is OK, it will sound once again. If it is not two beeps, burning is failed. You can capture the sound instead of LED lights, so this will improve the efficiency of burning.  On-board LED indicators, HEART BEAT led lights up like a breathing light when powered normally. During programming, the PROG indicator flashes until it finishes. If the programming is unsuccessful, the ERROR indicator (red) will light.  Onboard 28P locking seat for Atmega328P, Atmega168P, Atmega8 bootloader burning.  Onboard ISP_6PIN interface, for the external for Arduino board bootloader burning. On-board ISP_10PIN interface.  On-board FT232RL and CH340G USB to TTL programmer interface for uploading code to the chip on the 28P locking seat.  Specifications Resources Sample Code for programming ATmega328p Tutorial

Si5351 I2C 25MHZ Controller Clock Generator ₹ 589.99 ₹ 999.00
Description: Never hunt around for another crystal again, with the Si5351A clock generator breakout from Adafruit! This chip has a precision 25MHz crystal reference and internal PLL and dividers so it can generate just about any frequency, from <8KHz up to 150+ MHz.   The Si5351A clock generator is an I2C controller clock generator. It uses the onboard precision clock to drive multiple PLL's and clock dividers using I2C instructions. By setting up the PLL and dividers you can create precise and arbitrary frequencies. There are three independent outputs, and each one can have a different frequency. Outputs are 3Vpp, either through a breadboard-friendly header or, for RF work, an optional SMA connector.   We put this handy little chip onto it's own breakout board PCB, with a 3.3V LDO regulator so it can be powered from 3-5VDC. We also put level shifting circuitry on the I2C lines so you can use this chip safely with 3V or 5V logic. Best of all, we even have a great tutorial and library to get you started! Our code is designed for use with the for Arduino microcontroller and IDE but is easily ported to your favorite platform with I2C support.
