The Kitronik environmental control board provides a variety of sensor inputs and connection points for the BBC micro:bit and the ability to control outputs for devices such as a water pump, fan, servo motor or heating element. This makes it ideal for feedback control systems The BBC micro:bit mounts directly to the board via an integral end connector. The micro:bit can then read the input from the integrated BME 280 ambient temperature, barometric pressure and humidity sensor, as well as the real-time clock. There is a built-in piezo transducer, 2 1A outputs, 3 ZIP status LEDs, a ZIP LED extension connector and servo motor output. In addition to these, 3 BBC micro:bit terminals are separated into croc-clip connectors as further inputs and outputs, along with pads for 3V and GND Power is supplied via the built-in 3xAA battery socket or the 2.1 mm DC socket. There is an on/off switch to control the power supply to the board and there is a green LED to indicate when the board has been powered up. The board also generates an adjustable 3V power supply which is fed to the end connector to power the mounted BBC micro:bit, removing the need to power the BBC micro:bit separately Features: Build automated systems that react to environmental changes The board has a number of sensor inputs that can be coded to control the board’s outputs There is a built-in BME 280 environmental temperature, barometric pressure and humidity sensor and a separate real-time clock (RTC) The board also features an integrated piezo transducer, 2 x 1A outputs, 3 ZIP status LEDs, a ZIP LED extension connector and servo motor output. In addition to these, 3 BBC micro:bit terminals are separated into croc-clip connectors as further inputs and outputs, along with pads for 3V and GND It can be powered via the built-in 3xAA battery holder or the 2.1 mm DC socket, while power is controlled via the on/off switch with adjacent LED indicator There is also a solar cell input that can be used in conjunction with rechargeable batteries The board generates an adjustable 3V power supply to power the micro:bit via the i/o connections of the end connector Program it with MakeCode
