This PSU board is designed to fit directly on to a standard breadboard such as our BB400T and BB830. to give 2 power rails, 5V or 3.3V, Rail voltages are switch selectable. It can powered by 7-12V at the DC socket or 5V via the micro USB socket.
Solderless Female to Female Jumper Leads in a set of 40
This set of coloured female to female jumper leads can be used together or peeled apart into smaller sets or single leads. They are great for prototyping with boards like Arduinos and Raspberry Pi.
With 10 different colours and 4 of each colour, it's easy to keep track for quick fault finding.
Colours: Red, Orange, Yellow, Green, Blue, Grey, Purple, Brown, Black and White
This handy compact panel meter will display the voltage and current clearly. It is ideal for a bench power supply or any project that requires accurate voltage and or current measurement. The meter can either be powered from the supply it is measuring if it is between 4.5-30VDC or from an independant power source.
Voltage Measurment : 0 - 100VDC
Current Measurment : 0 - 10ADC
Working Voltage : 4.5 - 30VDC
Dimensions : (W)48mm x (H)29mm x (D)22mm
Connetions
Red (Thick) - Voltage in for Current Measurment
Black (Thick) - Voltage out for Current Measurment
PIR sensor module for Arduino and other microcontroller projects
The HCSR501 is a PIR (Passive Infra-Red) sensor that can detect the presence of people by measuring the infrared radiation radiated by the body. It can be used in a vast and diverse number of projects, including but not limited to: automated lighting systems, burglar alarms, automated door systems, etc.
Principle of operation All objects with a temperature above absolute zero (0 kelvin) emit electromagnetic radiation. The higher the temperature of the object, the smaller the wavelength of the radiation emitted. The normal human body temperature is 37°C (310.2 kelvin) and it therefore emitts infrared radiation (mostly at a wavelength of 12µm). The PIR sensor can sense when a person has walked into its field of view by measuring the difference in the infrared radiation received from the ambient environment and the human body.
Voltage : 5-20VDC
Power Consumption: 64mA Logic output: 3.3V Range: 7 metres, (<120°) Lock Time: 200 miliseconds Operating temperature range: between -15°C and 70°C
2A DC-DC Step Up Voltage Regulator With USB (Boost Converter)
This tiny step-up voltage regulator uses high frequency switching to make a very efficient DC-DC converter. It can take 2V to 24VDC in (or 5VDC via USB) and step it up to a higher voltage, up to a maximum of 28V at up to 2A (output). The voltage is set with the small multi-turn potentiometer.
Voltage in : 2V - 24VDC
Voltage out : 2.5V- 28VDC
Maximum Output Current : 2A
Dimensions : 36mm x 17mm

Photoresistor module for Arduino and other microcontroller projects
This module has a light dependent resistor (LDR) that will change value (resistance) depending on how much light there is on the sensor.
