1. Adafruit MicroSD card breakout board+
Breakout board with a microSD socket and level shifter for easy connection of the circuit to 5V systems.
- Onboard 5V-3V voltage regulator, 150mA - suitable for power-hungry cards.
- Integrated level shifter makes it suitable for 3V, 3.3V, and 5V projects.
- Activity LED for writing and reading.
- Four mounting holes.
- Push-push socket for easy insertion and removal of the card.

Wiring to the Arduino (for using the SDfatLib):
GND to Ground (yes, really!)
5V to 5V
CLK to Pin 13
DO to Pin 12
DI to Pin 11
CS to Pin 10.
2. Adafruit ADS1115 16-Bit ADC 4 Ch. w/Gain Amplifier
For microcontrollers without an analog-to-digital converter or when
you want a higher-precision ADC, the ADS1115 provides 16-bit precision
at 860 samples/second over I2C. The chip can be configured as 4
single-ended input channels, or two differential channels. As a nice
bonus, it even includes a programmable gain amplifier, up to x16, to
help boost up smaller single/differential signals to the full range.
We like this ADC because it can run from 2V to 5V power/logic, can
measure a large range of signals and its super easy to use. It is a
great general purpose 16 bit converter.
The chip's fairly small so it comes on a breakout board with ferrites
to keep the AVDD and AGND quiet. Interfacing is done via I2C. The
address can be changed to one of four options (see the datasheet table
5) so you can have up to 4 ADS1115's connected on a single 2-wire I2C
bus for 16 single ended inputs.
To get you started, we have example code for both the Raspberry Pi
(in our Adafruit Pi Python library [1]) and Arduino (in our ADS1X15
Arduino library repository [2]) Simply connect GND to ground, VDD to
your logic power supply, and SCL/SDA to your microcontroller's I2C
port and run the example code to start reading data.

3. Adafruit Magnet sensor
This door sensor is a reed switch made of ABS plastic. Normally, the reed is open (no connection between the two terminals). The other half is a magnet. As soon as the magnet is less than 13 mm away from the switch, the switch closes (connection between the two terminals). These sensors are mostly used to determine whether a door or drawer is open or closed. Therefore, both parts of the sensor have mounting holes, and 4 screws are included in the package.

- High-quality controller with RAM buffering to relieve the microcontroller.
6. Adafruit RGB Matrix HAT RTC for Raspberry Pi
With this HAT for the Raspberry Pi A+/B+, you can easily control all HUB75 RGB LED matrices with 16x32, 32x32, or 32x64 LEDs. You can even cascade multiple matrices; the power of the Raspberry Pi is sufficient to control approximately 32x128 LEDs. A 5V power supply is required to power the LEDs. This is not included in the package along with the LED matrices and the Raspberry Pi and must be ordered separately. The matrix is delivered as a kit. All SMD components are already soldered; only the Pi header, HUB75 connector, and power connector need to be soldered. If you prefer not to do this yourself, we can provide the shield pre-assembled for an additional charge. A CR1220 coin cell battery is required for the RTC (not included). Simple design: just plug it in and run the Python code, protection switch: a 5V power supply can be directly connected to the reverse-polarity protected connector on the HAT, onboard level shifter: converts 3.3V to the required 5V, DS1307 Real Time Clock: so your Pi keeps track of time even when restarted.
7. Adafruit Pi-EzConnect Terminal Block Breakout HAT

10. Adafruit Neopixel Stick
Use only one microcontroller pin to control as many LEDs as you can chain together! Each LED is addressable, as the driver chip is located within the LED. Each LED has a constant current drive of about 18 mA, ensuring that the color remains very consistent even when the voltage varies. No external current-limiting resistors are needed, making the design sleek. Power the whole setup with 5 VDC (4-7 V works) and you are ready to rock.
