Product of the day: our Motoron M3T453 family makes it easy to control DC motors through an I²C interface, with a wide 4.5-44V operating range and 0.8A continuous (2A peak) per channel. Each unit can control up to three motors, and units can be chained with other Motorons to control dozens of motors with a single I²C bus. Different versions offer different connector options, including JST SH-style connectors that work with our assortment of JST SH-style cables. Today we're highlighting the version with soldered 0.1″-pitch headers, on sale for $15.95!

New products: eagle-eyed observers might have spotted that the "first production" picture we shared the other day was actually of the products released today: the large, 6-layer version of the carrier for the Allegro MicroSystems ACS37100 current sensor, which uses tunneling magnetoresistance (TMR) to deliver 10MHz bandwidth. Our initial stock of chip continues to be limited, but you can try one out today for an introductory special price of $17.95.

Product of the day: our versatile 6-channel Micro Maestro makes it easy to control servos through USB, TTL serial, or internal scripting. The channels can also be configured as general-purpose digital outputs or analog inputs for use with sensors or other devices. Free PC/Linux software is available for configuration, creating motion sequences, and writing scripts, and an SDK is available for writing your own software. Get one today for $21.95.

New products: our large carrier board versions with 6 layers of 2 oz copper make the most of the new Allegro MicroSystems ACS37200, which feature an innovative package with just 50 µΩ typical primary conductor resistance and a high isolation voltage rating. As with the other similar products we have released recently, quantities are limited until we can get higher production volumes of these new components. The first two variants we have available are the ±200A, 3.3V and ±100A, 5V versions. Try one out today for $22.95!

New product: if you've been watching our new product announcements this month, you probably figured out this one was coming: the new D24Z3F5 isolated regulator combines a Texas Instruments UCC33420 isolation module with a buck regulator in front of it, providing an isolated 5V output from a 5.5-36V input. Try one on introductory special for just $5.25!

Product of the day: our carriers for the Texas Instruments TPS2116 power multiplexer make it easy to switch up to 2.5A between two power sources in the range of 1.6V to 5.5V. This is often handy when making devices that can be powered from USB and another source, so we've included a USB C connector on these boards (though the mux can be used without using the USB aspect of the boards). There are two versions available, one with priority given to the USB power source, and the other with USB set as the secondary source. Grab some today for $3.95 each!

Product of the day: our compact carriers for Allegro MicroSystems APM81815 step-down voltage regulator are our highest input voltage regulators, supporting a 72V maximum (80V abs. max) input voltage while delivering up to 1.5A at 3.3V, 5.0V, 5.35V, or 12V out (max continuous current depends on operating conditions; see our performance graphs for details). Pick up some today for $5.75 each.

New products: check out the tiny 2x3mm package straddling the isolation slot on our new Texas Instruments ISO652x 2-channel digital isolator carriers! We have the two "non-F" versions available so far that default to a high state when the other side is not powered, and the F versions will be available as soon as our or orders of these cool chips arrive. Try one now for just $1.50 each!
