The SparkFun Photodetector Breakout is an updated version of the SparkFun Particle Sensor Breakout and includes the MAX30101, a highly sensitive optical sensor and successor to the MAX30105 and MAX30102. The MAX30101 Breakout utilizes a photon detector to measure the amount of returning light reflected back from the LEDs. This is useful for various applications like particle (i.e. smoke) detection, proximity measurements and even photoplethysmography.

Two new SparkX boards also released this week: the Qwiic Power Switch and the Qwiic PT100. The Qwiic Power Switch (QPS) will help you control some of the high-power Qwiic boards in the world, while the Qwiic PT100 will allow you to measure temperature with a 100 Ohm Platinum Resistance Thermometer (PRT).

These 2x20 pin female headers (in 13.5mm/9.8mm and 16mm/7.3mm sizes) allow you to extend the reach of any board with the standard 2x20 GPIO pin footprint, like the Raspberry Pi, Google Coral, and NVIDIA Jetson. You can also solder it to Pi HATs that do not have headers on the board (assuming that the board is only populated on the top, or the height of the components do not get in the way if it is a two-layer board).

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!
