Hello everyone, and welcome to this week's Friday Product Post. We have five new products available today, starting with the Qwiic SGP30 Air Quality Sensor. The SGP30 board is another graduate from SparkX, and one of the most capable air quality sensors in our catalog. After our new sensor we have the new Raspberry Pi 4 Desktop Kit (a 2GB version and a 4GB version) that lets you hook up your own HDMI capable monitor, turning it into a cheap PC for your home or office! Last up today are two new Zio Qwiic boards, an OLED board and a 16-servo controller. Let's take a closer look!

Air quality readings within 15 seconds!

SparkFun Air Quality Sensor - SGP30 (Qwiic)

1 Retired

The SparkFun SGP30 Air Quality Sensor tracks the quality of the air in your room or house by monitoring the volatile organic compounds (VOCs) around you. Indoor air quality (IAQ) sensors are great for measuring CO2 and VOCs, but some of them require a burn-in time of 48 hours, and a 20-minute start up time. By comparison, the SGP30 Air Quality Sensor can return valid IAQ readings within 15 seconds of powering up! The SGP30 communicates via I2C, so naturally we broke out the pins on the sensor to Qwiic connectors so you can easily connect it to SparkFun's ever growing Qwiic Ecosystem!

The SparkFun Raspberry Pi 4 Desktop Kit includes everything you need to turn any monitor with an HDMI port into a desktop PC. If you're looking to create a PC or Media Center with the Raspberry Pi 4 (in the form of a 2GB version and a 4GB version), this is the kit for you. All the components were chosen and tested to create the highest quality experience and allow the Pi to work to its full potential. The raw 64GB memory card has blazing fast read/write speeds that bring updates down to three minutes! The card included in this kit passes the Raspberry Pi SD Card Speed Test and comes blank with no distribution, allowing you to choose from a multitude of operating systems or projects built specifically for the Pi.

Zio Qwiic OLED Display (0.91 in, 128x32)

This Zio OLED Display features a whopping 128x32 pixels in a small 0.91” (diagonal) frame – that’s 4,000 itsy-bitsy LEDs. As an OLED, it comes with all the perks of being able to emit light (unlike LCDs). There's no backlight layer here, which means it’s thinner, consumes less power, and has higher contrast. With this size, it can display up to three lines of text.

Zio 16 Servo Controller (Qwiic)

2 Retired

With the Zio 16-Channel 12-bit PWM controller using the PCA9685 from NXP Semiconductors, you can control up to 16 servos or other PWM-controllable components via I2C. Each output can be off or on (no PWM control), or set any channel to its own PWM frequency and duty cycle. The PCA9685 operates with a supply voltage range of 2.3 V to 5.5 V, and both the inputs and outputs are 5.5-volt tolerant. Servos can be connected directly to output pins (up to 25 mA, 5.5 V) or controlled with external drivers for more power-hungry applications.

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 or Facebook. We’d love to see what projects you’ve made!

Never miss a new product!
