About the unit
Through this unit,
pupils should be able to:
- understand the
design features and operation of electronic control sub-systems
- identify the need
for and constraints on the development of electronic systems
- design, model
and test simple electronic circuits
- design printed
circuit board (PCB) masks and use them to create a PCB, if appropriate
- combine circuit
and product design to produce a high-quality electronic product
- design and model
potential products to show what they will look like and to confirm that
they are appropriate for their intended purpose.

Product evaluation
Organise a range
of activities that give pupils an opportunity to:
- examine, describe
and evaluate how electronics are used in sensing products
- explore situations
in which electronic devices could usefully enhance the care of someone
or something
- explore the use
of feedback in products
- explore and evaluate
the working of a range of electronically controlled devices, including
those that incorporate embedded computer control
- examine some of
the values issues, in particular environmental issues, that are raised
by the development of electronic systems.

Design and make
assignment
During the DMA, pupils
would be expected to:
- research the background
to the setting, seeking the opinions of potential users of the product
and using the information they collect to inform their own designing
- draw up a detailed
design specification for an electronic product, in a setting that they
choose, specifying criteria, eg aesthetics, technical function, usability,
reliability, maintenance, quality, health and safety implications
- carry out preliminary
product and electronic modelling to explore and test their thinking
and correct their working before deciding on a final proposal
- use a sequence
of drawings, including PCB designs, to clarify and communicate detail
before making
- make a compact
casing that houses the product's components effectively.
