Thank you very much for your support and advice in 2021！
As the new year has come, we list the top 10 DFRobot Bestselling of 2021. Let's check what those tops are!
This microcontroller supports WiFi and Bluetooth dual-mode communication and features a small size, ultra-low power consumption, on-board charging circuit, and easy-to-use interface, which can be conveniently used for smart home IoT, industrial IoT applications, wearable devices, and so on.
The DFPlayer Mini is a small and low-cost MP3 module player with a simplified output directly to the speaker.
I'm Maqueen Plus V2, the latest version of the STEAM educational robot Maqueen Plus. Optimized with more expansion ports, larger capacity power supply, and larger body, I can be perfectly compatible with more peripheral components like HuskyLens AI camera and Maqueen Mechanic kits, which makes me an accessible STEAM robot teaching tool for primary and secondary students. I'm not only suitable for classroom teaching, but also can be used for after-school extended exercises and robot competitions.
This kit includes Solar Power Manager 5V and Semi-Flexible Monocrystalline Solar Panel (5V 1A).
Beetle CM-32U4 is a micro Leonardo controller with an onboard charging chip.
As an upgraded version of the DFRobot Beetle Board, this board is greatly optimized in integration and usability, which makes it well applicable to Arduino projects that require compact size and long service life.
This expansion board not only leads to 9 micro:bit onboard GPIO interfaces, but also comes with 4-way motor drives and 8 servo interfaces, of which 4-way motor drives can be reused as 2-way stepper motor drives.
Ultrasonic distance sensor determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse. This is an easy-to-use commercial-grade ultrasonic sensor module of high performance and reliability, featuring a much smaller blind zone, wider sensing angle, and a certain penetration power(smog, dust) compared with other similar sensors.
The water pressure sensor can compatible with multiple Arduino controllers. Coordinate with a DFRobot Gravity IO Expansion Shield, the water pressure sensor can be plugged into an Arduino board, wiring-free. Put it with Solenoid Valve, Water Turbine Generator and other sensors, you can build a smart water control system.
Introduction: DFrobot Huskylens is equipped with multiple functions, such as face recognition, object tracking, object recognition, line tracking, color recognition, and tag(QR code) recognition.
Introduction: Gravity: Analog TDS Sensor/Meter for Arduino is an Arduino-compatible TDS Meter Kit for measuring the TDS value of the water, to reflect the cleanliness of the water. TDS meter can be applied to domestic water, hydroponic and other fields of water quality testing.
