This is a D1 Key Expansion Board 1 Button Shield. This Button shield is commonly used with a great variety of applications. By default, the button is connected to the D3 I/O port on the WiFi D1 mini. If you wish to use another I/O port, just cut off the connection to D3 and solder it to another pad, as needed.

Features:

1. The button is connected to the D3 I/O port on the WiFi D1 mini.
2. This button is used to Control light operations.

Package Includes:

1 x D1 Key Expansion Board 1 Button Shield
1 x Berg Pins

This is a STEMMA I2C breakout for the Infineon OPTIGA TRUST M SLS 32AIA.

OPTIGA Trust M is the next generation of Trust X. OPTIGA Trust M brings RSA 1K/2K + ECC256/384.

A crypto authentication chip much like the ATECC608 STEMMA we put into the shop last week, but with: ECC NIST P256/P384, SHA-256, TRNG, DRNG, RSA® 1024/2048 and 4.5K of user memory.

This chip can store your private keys securely, as well as generate true random numbers, which is what we’ve got going on in this demo below. Check out https://github.com/Infineon/optiga-trust-m for the Arduino library

Comes with a bit of 0.1″ standard header in case you want to use it with a breadboard or perfboard.  Four 2.5mm (0.1″) mounting holes for easy attachment.

Package Includes:

1 x Adafruit Infineon Trust M Breakout Board

The DS3502 I2C Digital Potentiometer allows you to let your microcontroller adjust the resistance for you! Talking over an I2C bus, your Arduino, CircuitPython board,  or Python-powered computer can talk to the DS3502 and tell it to vary its resistance at your back and call.

Working with the DS3502 is easy as an I2C controllable pie. We’ve put it on a breakout PCB with the required support circuitry and SparkFun qwiic compatible STEMMA QT connectors to allow you to use it with other similarly equipped boards without needing to solder.

This handy little helper can work with 3.3V or 5V micros, so it’s ready to get to work with a range of development boards. The DS3502 is a simple chip that does one thing well and so it’s very easy to work with. Wire it up and set the value for the wiper, that’s it. To make things even easier we’ve gone and written Arduino and CircuitPython/Python 3 drivers to simplify interfacing with your new knob-replacing friend.

The wiper value is a 7-bit number meaning there are 128 possible levels of resistance to choose from 0-10K ohms. You can even set a default value that will be set on power-up. The analog voltage-controlled can be from 4.5-15.5V. Additionally, you can use the address jumpers or pins to set the I2C address to one of four values, allowing you to have four DS3502s on the same I2C bus.

Package Includes:

1 x Adafruit DS3502 I2C Digital 10K Potentiometer Breakout – STEMMA QT/Qwiic

Arduino Nano IO Expansion For Arduino Nano is specifically designed to facilitate an easy connection between  Arduino Nano. In essence, it expands for the Arduino Nano controller to link those devices in a simple and trouble-free manner. NANO IO Shield Expansion Board For Arduino Screw Terminals is a small simple Arduino Nano extension board, it will be the Nano all pins of derivation, convenient connection. IO Expansion Shield For Arduino Nano is specifically designed to facilitate an easy connection between Expansion Shield For Arduino Nano and many other devices. In essence, it expands for the Arduino Nano controller to link those devices in a simple and trouble-free manner. This is a terminal adapter for the Arduino Nano.
