Blank ATmega328P chip - ready for you to mess around with

It can resist the strong light environment of 60klux and realize high-frequency and high-precision distance measurement indoors and outdoors

like other LEDs it's not recommended to drive them in 'voltage' mode

Can update IoT firmware directly from Raspberry Pi no other accessories required

MB7374 HRXL-MaxSonar-WRST7 SF_Sound and this little module canFeatures of the weather resistant MB7374, HRXL MaxSonar WRST7, include millimeter resolution, short to long distance detection, range information from 500mm to 5000mm for the nearest detectable target, heightened sensitivity over our standard sensors, a 6Hz read rate, and various output options: pulse width, analog voltage, and TTL serial. The MB7374 from the HRXL MaxSonar WRS line of outdoor sensors is a rugged ultrasonic sensor component module.
