Pass the Buck
A new Analog MEMs Microphone Breakout is now available as well as two new 5V Buck Regulators.
Hello everyone and welcome to another Friday Product Post here at SparkFun Electronics! This week, we have a handful of new products to show off and since you loved the Audio Codec Breakout so much the other week, we'll start with the new Analog MEMs Microphone Breakout! These two boards pair perfectly together so if you are looking for a board with a ridiculous Acoustic Overload Point and high dynamic range, we couldn't recommend this one more! Following that, we have 5V versions of our BabyBuck and Buck Regulator Breakouts. We wrap the week with a new, super-thin speaker. On to our new products!
An ultra-high AOP for your Audio project!
The SparkFun Analog MEMS Microphone Breakout makes it easy to work with the Vesper VM2020 analog microphone. The VM2020 is an ultra-high Acoustic Overload Point (AOP), high dynamic range, differential analog output piezoelectric MEMS microphone. What separates this from other analog MEMS microphones is that it was designed to be used in loud environments. Additionally, this microphone consists of a piezoelectric sensor and circuitry to buffer and amplify the output. It has an acoustic overload point of 152dB SPL for audio capture in loud environments.
The SparkFun 5V BabyBuck Regulator Breakout features the AP63357 from Diodes Inc., a 3.5A synchronous buck converter with a wide input voltage range of 3.8V to 32V. The fully integrated 74mΩ high-side power MOSFET/40mΩ low-side power MOSFET provides a high-efficiency step-down DC/DC conversion.
This full-size, 1in. x 1in. version of our SparkFun 5V Buck Regulator Breakout is configured to provide a regulated 5V output and features a high-voltage EN (enable) control pin that is rated up to 32V. The fully integrated 74mΩ high-side power MOSFET/40mΩ low-side power MOSFET provides a high-efficiency step-down DC/DC conversion.
If you want to get some sound out of your project but have a tight space budget, this is a good way to do it. This 2.5W, 4 Ohm speaker is only 28mm in diameter and just over 4mm thick. The cable is roughly 180mm long and terminates in a 2-wire JST connector.
That's it for this week. 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! We'll be back with more new products next week so make sure to check back then. Happy hacking!
