Adafruit MCP9600 I2C Thermocouple Amplifier - K, J, T, N, S, E, B and R Type T
US$22.34
Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The Adafruit MCP9600 does all that for you, and can be easily interfaced with any microcontroller or single-board-computer with I2C. Inside, the chip handles all the analog stuff for you, and can interface with just about any thermocouple type: K, J, T, N, S, E, B and R type are all supported! You can also set various alerts for over/under temperature, and read the thermocouple (hot) temperature and the chip (cold) temperature. All this over common I2C.

2.13" Flexible Monochrome eInk / ePaper Display - 212x104 Monochrome
US$26.95
This display is true E-Ink / E-Paper, once an image is displayed it will stay even once you remove all power. The image is also high contrast and very daylight readable. It really does look just like printed paper! This flexible display sports a 2.13" monochrome (black and white) display. It has 212x104 black ink pixels on a white-ish background. This is the same resolution as the 2.13" Tri-Color display, but doesn't have a red ink layer. The monochrome displays also take a lot less time to update, only a couple seconds instead of 15 seconds.

Adafruit INA260 High or Low Side Voltage, Current, Power Sensor
US$16.15
This breakout board may well be the last current sensing solution you ever need to buy. Not only can it do the work of two multimeters, but it can do it with amazing precision and flexibility. With it you can measure high or low side DC current, the bus voltage, and have it automatically calculate the power. It can do so over impressive voltage, current, and temperature ranges with better than 1% accuracy, all while delivering the data in an easy to use format over I2C.

Adafruit HUZZAH32 – ESP32 Breakout Board
US$19.06
This breakout is basically the 'big sister' of our HUZZAH 8266, but instead of an ESP8266 it has the '32! We've pared down our popular Feather ESP32, removing the battery charger and USB-serial converter. You just get a regulator, some protection diodes, two buttons and an LED. For some projects, where price and size are at a premium, you can program this board over the 'FTDI cable' breakout when needed, and leave it alone otherwise.

Adafruit TPL5110 Low Power Timer Breakout
US$7.63
The Adafruit TPL5110 Power Timer is a stand-alone breakout that will turn any electronics into low-power electronics! It will take care of turning your project on/off using a built in timer that can vary from once every 100ms up to once every two hours. Basically, the TPL will turn on periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely turn off the power. If the TPL does not receive a signal by the set time-out, it will reset the device like a watchdog timer.

Adafruit TPL5111 Low Power Timer Breakout
US$9.17
The Adafruit TPL5111 Low Power Reset Timer is a stand-alone breakout that will turn any electronics into low-power electronics! It will take care of enabling & disabling your electronics using a built in timer that can vary from once-every 100ms up to once every two hours. Basically, the TPL will set an enable pin high periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely disable the project by setting the enable pin low. If the TPL does not receive a signal by the set time-out, it will reset the device like a watchdog timer.

TV-B-Gone Kit - Universal v1.2
US$29.95
The TV-B-Gone is a kit that, when soldered together, allows you to turn off almost any television within 150 feet or more.  It works on over 230 total power codes - 115 American/Asian and another 115 European codes.  You can select which zone you want during kit assembly. This is an unassembled kit which means that soldering is required - but it’s very easy and a great introduction to soldering in general.  The kit’s powered by 2x AA batteries - that aren’t included - and the output comes from 2x narrow beam IR LEDs and 2x wide-beam IR LEDs.

ADXL343 - Triple-Axis Accelerometer (+-2g/4g/8g/16g) w/ I2C/SPI
US$9.17
Analog Devices has followed up on their popular classic, the ADXL345, with this near-drop-in-replacement, the ADXL343. Like the original, this is a triple-axis accelerometer with digital I2C and SPI interface breakout. It has a wide sensitivity range and high resolution, operating with an 10 or 13-bit internal ADC. Built-in motion detection features make tap, double-tap, activity, inactivity, and free-fall detection trivial. There's two interrupt pins, and you can map any of the interrupts independently to either of them.
