Stepping Up Precision
Upgrade your bench with high-resolution sensing and robust motor control using the new Qwiic ADS1219 and PD Stepper, plus a variety of essential components.
Hello everyone and welcome back to another Friday Product Post here at SparkFun Electronics! This is the last Friday Product Post before the Thanksgiving holiday here in the States. This week, we have quite a few products to get through, but we'll start off with two new products that, we think, will become stamples to your workbench. We start with the new Qwiic ADS1219 24 Bit ADC that will help you measure even the smallest signals (like those from strain gauges or scientific sensors). Next, we have the new PD Stepper controller and driver for the standard NEMA 17 motor. The best part? It attaches directly to the back of the stepper motor! following that, we have a few more products from our Production stock that we are making available for sale including an RTC, MOSFET, and more!
As we mentioned earlier, next week is Thanksgiving in the United States, so SparkFun will be closed Thursday, November 27th and Friday, November 28th in observance of this holiday weekend. Any orders qualifying for same day shipping placed after 2:00 p.m. MST on Wednesday, Nov 26th will be processed on Monday, December 1st (and yes, that IS Cyber Monday).

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.
Stepper motors are fantastic for precision projects, but the setup is often a headache. You usually need a microcontroller, a separate driver board, a bulky 12V or 24V power supply, and a mess of wires to connect them all. The PD Stepper from Things by Josh solves this problem by consolidating everything into a single, powerful, and compact unit that mounts directly to the back of your NEMA 17 motor.
The RV-1805-C3 is an ultra-low power Real-Time Clock (RTC) module designed for high efficiency and reliability. This surface-mount device integrates the crystal (XTAL) directly into a hermetically sealed ceramic package, eliminating the need for external clock tuning and ensuring accurate timekeeping even in harsh environments.
This is a P-channel metal-oxide semiconductor field-effect transistor (MOSFET) designed for high-efficiency power management. With a drain-source voltage of 30V and a continuous current rating of 3.8A, it features very low on-resistance and a low gate threshold voltage. This makes it "logic level" compatible, allowing direct control via 3V-5V devices.
This high-reliability SMD tactile button is designed for compact interfaces. With a footprint of just 5.25mm and a low-profile height of 1.5mm, it fits easily into tight enclosures like remote controls, handheld instruments, or wearable devices.
The MIC5205 is an efficient linear voltage regulator with ultra-low-noise output, very low dropout voltage (typically 17 mV at light loads and 165 mV at 150 mA), and very low ground current (600 µA at 100 mA output). The MIC5205 offers initial accuracy better than 1%.
That's it for this week at SparkFun. We'll have more new products for you in two weeks after the Thanksgiving, on December 5th after our Thanksgiving Holiday. If you aren't already a subscriber to our New Product Newsletter, you really should be! As always, we can't wait to see what you make! Shoot us a tweet @sparkfun, or let us know on Instagram, Facebook or LinkedIn. Please be safe out there, be kind to one another! Happy hacking!
