Math & Automatic Touch Keyboard for micro:bit

Add real-time clock and environment sensing (pressure, temperature, & humidity) capabilities to the micro:bit with the Kitronik RTC Board. MakeCode compatible.  

With the development of IoT, there are so many mature IoT platforms emerging in both domestic and overseas market, but most of them are mainly designed for the professional, which could be very hard for the non-experts to get started. Therefore, we specifically developed this micro: IoT, a micro:bit-based IoT expansion board. Use the board together with DFRobot Easy IoT platform, lower the barrier of using IoT. This micro: IoT board is pretty cute and delicate, on which we integrated Wi-Fi, OLED, 2-way motor drive, 6-way IO port, 2-way IIC, 1-way serial port, 1-way buzzer, 3-way RGB, 2-way servo, Li-ion battery holder, charging circuit, emergency power interface, etc. So many resources for you to program! Even without complicated background knowledge, you can build your IoT applications in few steps! We designed the board as a cloud shape to make it more suitable for the theme of IoT. As for power supply, we selected CR123A 3.6V lithium rechargeable battery. This kind of battery features small size, high capacity, and high safety. What’s more, we add short circuit and reverse connection protection for the product to further improve the safety in using Li-ion Battery. It's an easy-to-use and efficient IoT teaching tool, using this product, you can learn lessons related to IoT, such as:

Sense the world around you with enviro:bit! It's loaded with sensors for air and weather, colour and light, and sound, and slots right onto your micro:bit. Just slot in your micro:bit, then code enviro:bit with the block-based Microsoft MakeCode editor, or with MicroPython in the Mu code editor. The sensors go hand-in-hand really well with the LED matrix on micro:bit, letting you graph sensors readings or have the LEDs react to sound, for example. Features Comes fully-assembled and ready to use BME280 temperature, pressure, and humidity sensor TCS3472 light and colour sensor MEMS microphone Compatible with micro:bit Microsoft MakeCode and MicroPython support No soldering required!

Environment Science Board for micro: bit is designed with highly symbolic trees, houses, and snowy mountains. On a wide and easy-to-use PCB, it integrates many sensor modules of nature and science. Including UV sensor, temperature sensor, humidity sensor, air pressure sensor, sound sensor, color sensor, light sensor, water temperature sensor, TDS water quality sensor, buzzer, OLED display, etc. This kit is rich in knowledge, including a wide range of applications. It is initial to observe and ease to play. Extended GPIOs are set and it supports gravity series sensors. The bottom is designed with PMMA (acrylic） to enhance the ease of use and durability.

Description The MonkMakes Sensor Board allows you to detect sound levels, temperature and light levels. It features ring pad connectors for use with crocodile clips make it easy to connect to the board to a microbit. Sound Level:It senses sound level with a MEMs, which is a microphone on a chip that also features a pre-amplifier circuit. You can then use the plot bar graph block in the Microsoft MakeCode editor to display the result on the microbits LED matrix. Temperature Level:The temperature output from the board is a voltage that indicates the temperature. This is then measured using an analog input on the micro:bit. If you want your temperatures in Fahrenheit, then multiply the temperature in degrees C by 9, divide the result by 5 and then add 32. Light Level:The light sensor uses a photo-transistor to measure the light level and produces an output voltage that increases as the light level increases. It has 3V and GND connectors on both sides of the board which make it possible to power another board, such as the Relay Board or Powered Speaker Board. Features: 3V and GND connections can be made from either side and allow you to power a second board such as the MonkMakes Relay Board or MonkMakes Speaker. LED ‘power on’ indicator. Reverse polarity protection. All three sensors are analog and can be connected to pins P0, P1 and P2 using alligator clips. Detects sound level with a MEMs (microphone on a chip) and a pre-amplifier. Uses a thermistor to measure temperature. Light level detection with a photo-transistor (0 to 1023). All three sensors are analog and can be connected to pins P0, P1 and P2 using alligator clips.
