Hello everyone and welcome to another Friday Product Post here at SparkFun Electronics! This week we have three new products, and it all starts off with the new Qwiic Buzzer, which includes an ATtiny84 with custom firmware to control the piezoelectric buzzer over I2C. Since it is equipped with two Qwiic connectors, this little audio board requires zero soldering to incorporate into your projects! Following that, we have a brand new and more economical MicroMod Single Pair Ethernet Kit. All you’ll need to get started with this kit is a MicroMod Processor Board! We wrap the week with a new black enclosure case for the extremely popular Raspberry Pi 5. Now, let’s jump in and take a closer look at all of this week’s new projects!

Look at all that Buzz!

The SparkFun Qwiic Buzzer adds simple beeps and buzzes to your projects via I2C. Make some noises to alert you when something interesting (or urgent) happens. Simply connect a Qwiic cable and load up some pre-written code to an Arduino to start making noises!

The board includes an ATtiny84 with custom firmware to control the piezoelectric buzzer over I2C. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still broke out 0.1″-spaced PTH pads if you prefer to use a breadboard to access the board’s I2C, power, trigger, and reset pins on the board’s edge. A 2.2kΩ pull-up resistor is included on the data and clock lines.

What IS Single Pair Ethernet, anyway?

The SparkFun MicroMod Single Pair Ethernet Kit demonstrates 10BASE-T1L Two-Wire Ethernet protocol within the SparkFun MicroMod ecosystem by using two SparkFun MicroMod Single Pair Ethernet Function Boards and including all the accessories to run a proof of concept example over 0.5 meters of cable, which can be helpful before installing application nodes 1700 meters apart to monitor remote equipment.

This kit is intended and includes the required hardware to provide proof of concept communication over 10BASE-T1L Ethernet. This connector type is no longer the main medium for Ethernet of the 10BASE-T1L variety. A MicroMod Processor board is not included with this kit and will need to be purchased separately for the parts included with this kit to function properly.

The Raspberry Pi 5 case is a refinement of the Raspberry Pi 4 case. With improved thermal features to support the higher peak power consumption of Raspberry Pi 5, it integrates a variable-speed fan. The fan is powered and controlled from a dedicated connector on the Raspberry Pi 5 PCB.

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!
