Happy Friday, everyone! This week, we have three new products that we've been excited to launch, starting with the new SparkFun Cryptographic Development Kit. This is a simple kit that provides everything you need to secure your next IoT project or idea (it also uses the ATECC508A, so you won't need to sign an NDA to use it)! Following that, we have a new version of our Qwiic Air Quality Sensor - this one improves the SGP30 to the new SGP40. We round out the week with a new wireless version of the new Raspberry Pi Compute Module 4.

It's been a bit. Welcome back, product videos!

SparkFun Cryptographic Development Kit


With the SparkFun Cryptographic Development Kit you will get everything you need to learn the fundamentals of cryptographic authentication and how to use the ATECC508A Cryptographic Co-Processor Breakout with the Artemis RedBoard to add a soaring level of security to your projects.

SparkFun Air Quality Sensor - SGP40 (Qwiic)

SparkFun Air Quality Sensor - SGP40 (Qwiic)


The SparkFun SGP40 Air Quality Sensor provides a measurement of the quality of the air in your room or house. The SGP40 is based on Sensirion's CMOSens® technology and uses a metal oxide (MOx) sensor with a temperature controlled micro hotplate and provides a humidity-compensated volatile organic compound (VOC) based indoor air quality signal. Both the sensing element and VOC Algorithm feature an unmatched robustness against contaminating gases present in real world applications enabling a unique long term stability as well as low drift and device to device variation.

The Raspberry Pi Compute Module 4 represents a huge change for the Compute Module line. The biggest change being the move from the DDR2 SODIMM connector form factor to a high density connector on the bottom of the board. But true to the line, the Compute Module 4 packs all the best features of the Raspberry Pi Model B 4 into a more favorable form-factor for embedded or OEM applications. This model has 2GB of LPDDR4-3200 SDRAM and 32GB of eMMC Flash storage along with the wireless capability (2.4GHz and 5GHz IEEE 802.11b/g/n/ac wireless LAN and Bluetooth 5.0)

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! Please be safe out there, be kind to one another, and we'll see you next week with even more new products!

Never miss a new product!
