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

This fully-featured UDA1334A I2S Stereo DAC breakout is a perfect match for any I2S-output audio interface. It’s affordable but sounds great! The NXP UDA1334A is a jack-of-all-I2S-trades: you can use 3.3V – 5V logic levels (a rarity), and can process multiple different formats by setting two pins to high or low. The DAC will process data immediately, and give you a clear, analog, stereo line level output. It’s even cool with MCLK-less I2S interfaces such as the Raspberry Pi (which it’s ideal for) – a built in PLL will generate the proper clock from the bitclock signal.

For inputs, you can use classic I2S (the default) or 16-bit, 20-bit or 24-bit left justified data. You can set it up to take an input system/master clock but we default-set it to just generate it for you, so you only need to connect Data In, Word Select (Left/Right Clock) and Bit Clock lines. If you want, there’s a mute pin and a de-emphasis filter you can turn on.

We put in plenty of ferrite beads, a low-dropout regulator, and the recommended band-pass filter so you get a very nice clean output. With a sine-wave generator we swept through 20-20KHz and saw no attenuation or distortion. Plug into either the 3.5mm stereo headphone jack or the breadboard-friendly pads. We think you’ll be pleased with this DAC!

Each order comes with one I2S Stereo DAC breakout and some header you can solder on.

Package Includes:

1 x Adafruit I2S Stereo Decoder – UDA1334A Breakout

The SparkFun ATECC608A Cryptographic Co-processor Breakout allows you to add strong security to your IoT node, edge device, or embedded system. This includes asymmetric authentication, symmetric AES-128 encryption/decryption, and much more. This ATECC608A has limited Arduino support and the complete datasheet is under NDA with Microchip.

This breakout board includes two Qwiic ports for plug and play functionality. Embedded in the chip is a 10Kb EEPROM array that can be used for storing keys, certificates, data, consumption logging, and security configurations. Access to the sections of memory can then be restricted and the configuration locked to prevent changes. Each ATECC608A Breakout ships with a guaranteed unique 72-bit serial number and includes several security features to prevent physical attacks on the device itself or logical attacks on the data transmitted between the device.
