Hello everyone! We have a couple new products this week, starting with our new Qwiic-enabled Pulse Oximeter and Heart Rate Sensor! That’s not all, though – we also have a new 55-piece Electric Hobby Screwdriver and a USB Power Meter with a Color TFT LCD.
Before we get to new products, keep in mind that today, September 13th, is the LAST day to take advantage of our Two Weeks of Free Event. If you want to pick up one of three free Qwiic sensors with the purchase of a Qwiic RedBoard or Artemis RedBoard, make sure to check out before 11:59 p.m. MT today!
Now, on to the new products!
The SparkFun Pulse Oximeter and Heart Rate Sensor is an I2C-based biometric sensor, utilizing two chips from Maxim Integrated: the MAX32664 Biometric Sensor Hub and the MAX30101 Pulse Oximetry and Heart Rate Module. While the latter does all the sensing, the former is an incredibly small and fast Cortex M4 processor that handles all of the algorithmic calculations, digital filtering, pressure/position compensation, advanced R-wave detection and automatic gain control. We’ve provided a Qwiic connector to easily connect to the I2C data lines, but you will also need to connect to two additional lines. This board is very small, measuring at 1 in x 0.5 in (25.4 mm x 12.7 mm), which means it will fit nicely on your finger without all the bulk.
This Electric Hobby Screwdriver Set is great for dealing with small screws in a variety of applications, all enclosed in a handy plastic carrying case with a magnetic lid. The real magic of this tool is the extensive bit collection included: 55 magnetic H4 hex bits (plus an extension rod)! Also included is a magnetic project mat to keep the screws you remove organized and prevent them from running away.
This USB Power Meter is a versatile little tool that can provide voltage readings down to 0.01V and current to 0.001A, displayed on the built-in color TFT LCD while your device is connected to a power source. You can also measure the capacity and power of battery packs/power banks, as well as temperature and cable impedance!
