Discover the World's Smallest PM Sensor from Bosch and SparkFun

The SparkFun Qwiic Particulate Matter Sensor features Bosch’s BMV080—the world’s smallest particulate matter sensor—measuring just 4.4 × 3.0 × 3.0 mm³, over 450 times smaller than comparable devices on the market. The air quality sensor uses an innovative design based on ultra-compact lasers with integrated photodiodes. It applies sophisticated algorithms to track the PM concentration directly in free space, without requiring a fan. It can detect PM1, PM2.5, and PM10 in real time to provide actionable data.

Within the enclosure is a breakout board populated with the BMV080 sensor, connected via its flexible cable with the FPC 13-pin 0.33mm connector. On the back of the board is a horizontal Qwiic connector to reduce the amount of soldering on the board.

The 1GB DDR4 RAM version of the Raspberry Pi 4 can run two 4K monitors simultaneously via two micro HDMI ports and features the long-asked-for, true Gigabit Ethernet. This creates a much higher-performing multimedia experience with the new Pi! In addition to two USB2 ports, the Raspberry Pi 4 also has two USB 3 ports, making data transfers much quicker over USB.

Check out this single-port, 30W PoE+ Injector, which enables PoE supply to PoE-enabled Raspberry Pi boards. This device can supply 55V, 550mA, and 10/100/1000 Mbps data rates to the Pi through a single ethernet cable connection. The power cable is sold separately. This will work with all Raspberry Pi single-board computers from the 3B+ onward (excluding the Zero series).

N20 motors are very popular for small-scale robot applications because they're super compact, powerful, and durable. The entire motor fits within the 12mm x 10mm profile of the gearbox, which has a gear ratio of 31.5:1 and a 10mm long 3mm diameter D-shaft. This pair also includes magnetic encoders with 14-pole magnets, enabling a resolution of 882 counts per revolution of the output shaft. They are rated for up to 12V, at which they can achieve a speed of 1000RPM at 0.06A.
