DAC, DAC, Goose!
A new 12-bit DAC is now available, and it's Qwiic capable!
Hello everyone and welcome back to another Friday Product Post here at SparkFun Electronics! We've been off for the last few weeks building up boards and kits that you have been ordering over the last few months, but this week, we made sure to take the time to release a board that was missing from our catalog, update a popular PNT board, and we took a look at some older boards that we thought could be dropped in price a bit.
We start the week with SparkFun's very own MCP4725 Qwiic 12 Bit DAC Breakout! This super economical digital-to-analog converter provides true analog generation with non-volatile memory and straightforward I2C integration, ensuring your microcontroller can handle analog tasks efficiently and consistently. Following that, the GNSS Timing Breakout upgrades to the ZED-F9T-20B from u-blox for some increased security and expanded reception options. Finally, make sure you stick around for some price drops on our existing DAC and ADCs. Let's dive in!

While most microcontrollers simulate an analog voltage using Pulse Width Modulation (PWM) to create a digital square wave, many projects require a smoother signal. The SparkFun MCP4725 Qwiic 12 Bit DAC Breakout allows you to get precise voltage outputs from a microcontroller over a Qwiic connection. This Digital-to-Analog Converter is an excellent choice for applications where PWM simply falls short, offering the precision needed for demanding electronics projects.
The SparkFun GNSS Timing Breakout is a specialized tool designed for applications where time is just as critical as position. Featuring the u-blox ZED-F9T-20B GNSS receiver, this board offers an impressive five nanoseconds of timing accuracy under clear skies without requiring any external GNSS correction data. Whether you are maximizing the efficiency of a 5G IoT network, synchronizing a distributed sensor grid, or building a high-precision NTP server, this breakout provides the ultra-accurate time reference you need.
This new version of the GNSS Timing breakout replaces the original ZED-F9T module, with the updated ZED-F9T-20B.
This Week's New Price Drops:
The SparkFun MCP4725 DAC Breakout provides accurate, 12-bit analog voltage output via I2C and features onboard EEPROM to store settings even after power loss. This makes it an excellent choice for sound generation, custom musical instruments, and a wide variety of creative electronics projects where standard digital signals fall short.

Running out of analog pins on your microcontroller is a common problem and the SparkFun Qwiic 12-Bit ADC is the simple, reliable solution. Built around the Texas Instruments ADS1015, this board adds four channels of I2C-controlled analog input to your project, configurable as four single-ended inputs or two differential pairs. To ensure you get the most accurate reading possible, the chip features a programmable gain amplifier (PGA). This allows you to "zoom in" on very small changes in analog voltage, adjusting the full-scale range from ±6.144V down to ±0.256V. This flexibility ensures you maximize the 12-bit resolution regardless of your sensor's output range.

Sometimes, the standard 10-bit or 12-bit ADC built into your microcontroller just isn't enough. When you need to measure minute changes in voltage with extreme accuracy, you need the SparkFun Qwiic 24-Bit ADC. Built around the Texas Instruments ADS1219, this board provides four channels of high-resolution analog input, configurable as four single-ended inputs or two differential pairs. To help you measure even the smallest signals (like those from strain gauges or scientific sensors), the chip features a programmable gain amplifier (PGA) with x1 and x4 gain settings. This allows you to "zoom in" on tiny voltage fluctuations with incredible precision all the way down to a resolution of 61.04nV per count!
