This is a super cool and tiny device! It offers three functionality, you could use this as your digital clock or read some temperature with the provided temperature probe on the back and even use it as a voltmeter to read low dc voltages if you are in a pitch. This device uses a four character seven segment display and neatly connected in the back the controller board that offers these features. Although the manufacture boast this device as a voltmeter, we tested to read up to 20vdc as the capability of this device. This unit comes with a JST-PH connect to supply power that can range from 4-20vdc. It is a an excellent choice for installing in cars that use a 12vdc battery.

CANBus protocol are commonly found in cars and in the industrial field for signal processing. There are many variations to this protocol, we recommend using this device as a 3.3v CANBus device. This product is perfect for beginners that are not familiar with this protocol to physical test and solidify their theoretical knowledge on the protocol. This version compared to the ARD-617 is more clear and organized in terms of the pinout. One side is for interfacing the canbus, whereas the other side is solely related to interfacing with your microcontroller!

This is a high voltage and current switch based on the IRF540, the breakout board allows users to connect a 5v microcontrollers to operate high wattage devices without worrying about frying their microcontroller. Essentially this device operates like a relay with the exception that a relay can withstand unexpected surge currents caused by parasitic capacitances present in any circuit, cables, and so on. An unfortunate trade-off, however, is that the larger contacts require larger package sizes.Whereas this electronic switch takes less space offering almost the same features.

Want to program your RGB LED strip to be a bit more "rhythmic" or "unpredictive"? This RGB LED Strip Shield contains all the components you need to build a super cool RGB (or other three channel) LED project with your Arduino. The shield has 3 outputs with pulse width modulation. Each can control any 12V load, at up to 3A. The shield has build-in IR receiver which allows the LED strip being controlled by an IR remote controller. A buildin fuse protects the LED strip from over current or any shortage by any reasons. It cares your hard work. This shield makes it possible to drive about 10 meter length RGB LED Strip with your Arduino processor, which almost require 10Amps(@12V) driving capability.

DFRobot FireBeetle series are low power consumption microcontrollers designed for Internet of Things (IoT) development. This Bluetooth controller combines Bluetooth Low Energy 4.1 with Arduino controller, offering functions similar to the former Bluno series but with lower power consumption. FireBeetle BLE 4.1 is compatible with Bluno series (BLE 4.0) and performs much better. It equipped with more stable DIALOG Bluetooth 4.1 chip, supporting maximum 4Kbyte/s transmission rate and low power consumption (25uA POWER DOWN). It can be directly applied to low power consumption application such as wearable and intelligent tools and so on. It also supports multiple Bluetooth cascade, KISS connection (approach connection) and compatible with Bluno series. Its connection can be realized by holding host BOOT and moving to the target peripheral device.
