Have some USB logic analyzer, multimeter or oscilloscope and bumping
up against the frustation of a shared earth ground? The Offspring
(known for being electrical engineers) wisely sang "Ya gotta keep'em
isolated!" Power and signal isolation improves common-mode voltage,
enhances noise rejection, and permits two circuits to operate at
different voltage levels.
This handy little low-cost USB isolator is exactly what you need to
provide protection against harmful noise, ground loops, surges, and
spikes. Works with any 1.5Mbps (low speed) or 12Mbps (full speed) USB
device. Not for high speed USB devices, often used for video cameras
(check your product to make sure its low/full compatible) Based on
Analog Device's USB isolators
It is particularly useful when paired with USB testing instruments,
you need to separate or isolate your eath ground (thru the USB
connector to the computer to the power plug) from your circuit for
high voltage, accident-protection, or floating ground needs. Best of
all, this USB isolator even has its own isolated 5V power supply that
can supply 100mA! Protect your computer or laptop, use one of these in
between your ports.

thorough command line tools that make it simple to deploy your code,
set WiFi credentials, and easily manage authentication needs. With the
Tessel 2 you will be able to interact with the physical world from
sensing to actuation to connecting with other devices. It should also
be noted that though the Tessel 2 is programmable in JavaScript it
does possess the ability to support other languages as well!
The Tessel 2 is equipped with a slew of on-board features including
two 10-pin module ports to add sensors and other external hardware,
two USB ports for camera peripherals and flash storage, a 10/100
supported ethernet port, and a microUSB connector for power and
tethered programming. Each Tessel 2 offers an 802.11 b/g/n WiFi setup,
a 580MHz Mediatek router-on-a-chip, a 48MHz SAMD21 coprocessor, and
64MB of DDR2 RAM with 32MB of flash.
Needless to say, the Tessel 2 has been designed from the ground up
with the fastest possible path to producing your projects. Simply plug
and play multiple modules and high-level APIs and you have a
development board that is levels ahead of most other development
boards!

The datasheet for the DS3231 explains that this part is an "Extremely Accurate I²C-Integrated RTC/TCXO/Crystal". And, hey, it does exactly what it says on the tin! This Real Time Clock (RTC) is the most precise you can get in a small, low power package.
Most RTCs use an external 32kHz timing crystal that is used to keep time with low current draw. And that's all well and good, but those crystals have slight drift, particularly when the temperature changes (the temperature changes the oscillation frequency very very very slightly but it does add up!) This RTC is in a beefy package because the crystal is inside the chip! And right next to the integrated crystal is a temperature sensor. That sensor compensates for the frequency changes by adding or removing clock ticks so that the timekeeping stays on schedule.
This is the finest RTC you can get, and now we have it in a compact, breadboard-friendly breakout. With a coin cell plugged into the back, you can get years of precision timekeeping, even when main power is lost. Great for datalogging and clocks, or anything where you need to really know the time.
Comes as a fully assembled and tested breakout plus a small piece of header. You can solder header in to plug it into a breadboard, or solder wires directly.
A coin cell is required to use the battery-backup capabilities! We don't include one by default, to make shipping easier for those abroad, but we do stock them so pick one up or use any CR1220 you have handy.

Wouldn't it be cool to drive a tiny OLED display, read a color sensor,
or even just flash some LEDs directly from your computer? Sure you can
program an Arduino or Trinket to talk to these devices and your
computer, but why can't your computer just talk to those devices and
sensors itself? Well, now your computer can talk to devices using the
Adafruit FT232H breakout board!
What can the FT232H chip do? This chip from FTDI is similar to their
USB to serial converter chips but adds a 'multi-protocol synchronous
serial engine' which allows it to speak many common protocols like
SPI, I2C, serial UART, JTAG, and more! There's even a handful of
digital GPIO pins that you can read and write to do things like flash
LEDs, read switches or buttons, and more. The FT232H breakout is like
adding a little swiss army knife for serial protocols to your
computer!
This chip is powerful and useful to have when you want to use Python
(for example) to quickly iterate and test a device that uses I2C, SPI
or plain general purpose I/O. There's no firmware to deal with, so you
don't have to deal with how to "send data to and from an Arduino which
is then sent to and from" an electronic sensor or display or part.
This breakout has an FT232H chip and an EEPROM for onboard
configuration.

With this 1-channel relay module you can easily control large loads with 5V of your Arduino or Raspberry Pi. The control lines of the relay are connected to screw terminals on the board. The load to be switched is also connected via screw terminals. For safety reasons, you should only operate the relays up to 30V. You can use a jumper on the relay module to switch the control from low level trigger to high level trigger.
