Unlock the secrets of nature with code, engineering, and the Kitronik Environmental Control Board for BBC micro:bit (V1 & V2)! This versatile board provides sensor inputs and control outputs ideal for environmental automation projects such as plant watering and greenhouse systems.The board slots a BBC micro:bit directly into an integrated edge connector, enabling input from the onboard BME 280 environmental sensor (temperature, barometric pressure, and humidity), a Real-Time Clock (RTC), and more. It features an onboard piezo buzzer, 2 x 1A high-power outputs suitable for water pumps, heater pads, or fans, 3 status ZIP LEDs, a ZIP LED expansion connector, and a servo output. Additionally, it offers 3 breakout micro:bit pins for croc-clip connections and pads for 3V and GND.Power the board using the onboard 3xAA battery holder or a 2.1mm DC Jack with an on/off switch and power indicator. The board provides a regulated 3V supply to power the micro:bit and a solar cell input to charge rechargeable batteries, promoting renewable energy integration.Code the board easily with MakeCode using Kitronik's custom blocks for simple programming, or dive deeper with Blocks, JavaScript, and Python for advanced projects. The board is also available as part of the Kitronik Smart Greenhouse Kit.Features: Compatible with BBC micro:bit V1 and V2 Onboard BME 280 sensor for temperature, humidity, and barometric pressure Real-Time Clock (RTC) for accurate timekeeping Onboard piezo buzzer 2 x 1A high-power outputs for devices such as pumps and fans 3 status ZIP LEDs and ZIP LED expansion connector Servo output and croc-clip breakout pins Power options: 3xAA battery holder, 2.1mm DC jack, solar cell input Regulated 3V supply for micro:bit power MakeCode custom blocks and compatibility with JavaScript and Python editors Technical Specifications: Operating Battery Voltage (Vcc): +5V max Operating 2.1mm Jack Voltage: +5V DC max (Centre Positive) Solar Cell Input: +5V max High Power Outputs: 2 channels (1A max each) High Power Output Control Pins: Pin 13, Pin 14 Additional I/O Pins: Pin 0, Pin 1, Pin 2 ZIP LED Control Pin: Pin 8 Piezo Buzzer Control Pin: Pin 12 Servo Control Pin: Pin 15 BME280 and RTC Control Pins: Pin 19, Pin 20 (I2C Lines) BME280 Operating Range: Pressure 300hPa - 1100hPa, Temperature -40°C to 85°C, Humidity 0% to 100% RH Contents:1 x Kitronik Environmental Control Board for BBC micro:bitDimensions: Length: 74.5mm Width: 66mm Height: 29mm Requires: BBC micro:bit V1 or V2 3 x AA Batteries or suitable power supply Optional accessories: water pump, silicone tubing, mini prong moisture sensor, crocodile clips, ZIP Stick, solar cell, rechargeable batteries, servo Resources: Datasheet Seven MakeCode online tutorials for Kitronik Smart Greenhouse Kit Guide to Adding a Solar Panel
