At the same time, the IoT:bit with an on-board buzzer for outside sound and an on-board RTC clock for timing without a power supply. Let's create your own IoT micro bit by makecode!

IoT:Bit: A RELIABLE TOOL TO ESTABLISH CONNECTION ACROSS DEVICES The IoT boards can help anyone fully grasp the digital apparatus of computers. Establishing interconnected networks amongst devices can be crucial in data analysis. IoT-based components are often used to speed up this task for a micro bit. IoT bit is a device that works as an internet extension for a micro bit. It is applied on circuit boards to improve the means of productivity by creating valid communication with the micro bit. IoT bit is a very compact tool that is made with complicated circuitry within itself. Anyone who wishes a reliable internet WIFI extension board for their micro bit should try out this component. Various sorts of tasks done by them can be improved manyfold through this seemingly minuscule module.

DESIGNED WITH A VARIETY OF FEATURES The IoT-based module is equipped with many handy features that can ensure the efficiency of the micro bit. The IoT bit uses an ESP8266 as a board for WIFI expansion for data transactions through the micro bit. Led by GVS, the board also has extended IO ports for the micro bit, which lets you add a variety of other parts. The onboard buzzer can be triggered from the outside, and the RTC clock within can stay functional even without a power supply. The IoT bit also has an earphone jack and an integrated buzzer. The design is very simplistic compared to the functions, as you can construct them any way you please. The four LEGO-like holes make them very adaptable when used in a micro bit.

RELIABLE HARDWARE The IoT:bit is a valuable component that itself is made out of smaller components. The hardware of any electrical entity can be deemed very important. Through the micro bit, the direct current is supplied via a USB at five volts. The expectation for maximum current is around 800mA, which is appropriate to keep the micro bit functional. The hardware stays operational from -25 to 80 degrees Celsius. The WIFI module used for the micro bit is labeled ESP8266. The ESP12F is very reliable as it is widely used in components similar to IoT bit. The passive buzzer is worth mentioning too. The RTC timing mechanics lets the device memorize the pace of time even after cutting off the power supply of the micro bit. RTC battery for the micro bit is something you can add in yourself. The battery requires a CR1220 cell. The coding port is a serial port in the micro bit that can delineate the IO slot.

EASY TO INSTALL & ACCEPTABLE SIZE Adding components to a micro bit can be difficult as it is a miniature computer. The IoT boards are very sizable addition to the micro bit. It has a surface area of fewer than 50 centimeters and is 23 millimeters in depth. The printed circuit board is an essential part of the entire system. The PCB thickness is about 1.5mm. IoT bit has four adaptable slots, which let them get attached to the micro bit. Each of these holes is 2.4mm in diameter.

INTERPHASE VARIABLES There is much to discuss a variety of functions visible on the interphase of IoT bit. The micro bit you use will probably have lots of potential in it, which you could not utilize because of not having the right component. IoT bit has a GVS leaded function had grants access to the electronic building module and also a functional 12C communication device. No need to reset the time every time you start the micro bit because of the RTC timing system.

This is a micro servo It only weights 20g and provides a 1.6kg.com torque. It will comes with a 3-pin control cable and mounting hardware.

Almost all the micro bit servo in the market have to be driven by 5V, but the normal working voltage for micro:bit is 3V. It is embarrassing to drive a 5V servo with a micro:bit. Thus, we have customized these two servos that can be driven by two batteries with the lowest working voltage at 2.7V. It is the first batch of the micro bit servo designed for the micro:bit in the market.

The high linearity makes its control more accurate. It is designed for micro:bit with high-linearity, which gives you a smooth feel of control.

Low working voltage, compatible to 3V-5.5V(With 2.7V at least), designed for micro:bit.

ELECFREAKS micro:servo is a kind of 360 deg analog servo. It is light and portable, a little bigger than 5 cent coin. It works at 3V voltage and uses pulse width to adjust speed of the servo rotation, which also can be used to make small robot modules, mechanical arm modules and intelligent car modules.

Smart Ai lens kits is an Artificial Intelligence module compatible with 3.3v~5v micro:bit expansion board which can be programmed graphically. Buy Smart Lens from us. Our ELECFREAKS micro:bit Smart AI lens kits are designed for children. The Smart AI lens kits can be applied in card identification, line-tracking, ball tracking, color identification, one-button to the quire, and face tracking.

The Elecfreaks Smart Home Material Pack is a customized wooden accessory pack for Octopus sensors. It is designed with fixing holes reserved for IOT:bit, Sensor:bit, Servo, and Octopus sensors, which enables us to show better results when building cases.

Compared with the complicated screw installation method, Elecfreaks have adopted an extremely friendly bolt-fixing method. Moreover, the assembly of this product is also very convenient. Just press it, and it can be assembled without any other accessories.

Elecfreaks Smart Home Material Pack is a wooden accessory set specially tailored for Octopus series sensors. It is no longer an ordinary circuit connection, but can show the use of sensors in a more scenario-based manner.

Often used with :
ElecFreaks Micro:bit Smart Home Kit
Elecfreaks Micro:bit Smart Climate Kit

ELECFREAKS micro:bit Tinker Kits is sourced from Singapore's training organization TINKER ACADEMY which has a professional team and a strong academic background. A variety of octopus sensors and lots of micro bit projects tutorials to help you create dozens of amazing digital maker micro bit projects! ELECFREAKS Octopus:bit is a kind of breakout board for micro:bit. It can lead out GPIO port, serial port, IIC port, and SPI port on the micro:bit board. The biggest feature of Octopus:bit is that it can switch electric level for some GPIO ports, which makes micro:bit available to be adapted to 5V sensors.

Plant Monitoring Device : Upload your code into the micro:bit and stick that moisture sensor into the base of your plant. You pots will be able to tell you when your plants are thirsty!
Music Machine: Since there are 5 buttons, we need to code 5 similar conditional statements. Each button controls a sound of a particular pitch. So press each buttion, we will get sounds of different pitches.
Electro-Theremin: We want to make sure the highest potentiometer value still corresponds to the highest note we can play. Check out the value of the lowest and highest notes in the micro:bit piano keys. Twist the knob to control alien noises!
Smart Light: Upload your code into your micro:bit. Walk into the dark with your new smart light, or place it in a room to brighten up when you walk in.

ELECFREAKS XGO Robot Kit V2 for micro:bit is a bionic quadruped robot dog kit specially designed for artificial intelligence education for teenagers. It can be combined with the micro:bit to perform graphical programming on MakeCode, which is more suitable for teenagers to learn to program.

ELECFREAKS XGO Robot Kit V2 for micro:bit is a bionic quadruped robot dog kit specially designed for artificial intelligence education for teenagers. It can be combined with the micro:bit to perform graphical programming on MakeCode, which is more suitable for teenagers to learn to program. With 15 DOF, it can perform and interact like a real pet dog, as well as pinch and carry with its robotic arm, allowing children to learn mechanics, electronics, programming, and AI as they play with it, and getting them prepared for the future life of AI.

Compared with the XGO V1, the XGO Robot Doc Kit V2 has three more high-quality digital servos, which can support more vivid and dynamic movements.

The XGO Robot Dog Kit V2 is equipped with a 6-axis IMU, joint position sensors, and current sensors to provide its own attitude feedback, which can be used for algorithm verification and secondary development. At the same time, it also has a speaker sensor, which makes the product more vivid.

Programme the joystik:bit to control XGO V2 through the makecode platform

Use the self-developed APP to control XGO V2

XGO Robot Dog Kit V2 is equipped with a 3-axis arm, which can realize intelligent gripping, pushing and handling
