Breadboard Canvas
SKU: 410‐385
The Breadboard Canvas provides a replaceable physical interface for the Analog Discovery
Studio. The large breadboardable surface features two regular sized solderless breadboards
appropriate for medium to large circuits. Two small breadboards provide connection to the six
available power supplies (3.3V, 5V, ±12V, and ± variable), and connections to the included I/O.
Two switches, LEDs, and buttons have been included on the Breadboard Canvas to provide
these typically hard to breadboard components with an easy‐to‐use interface. Each of the
power supplies can be switched on and off via slide switches to make powering off and on
circuits as convenient as possible. Power supply status is indicated by the power indicator LEDs.
This is the same Breadboard Canvas that is included with the Analog Discovery Studio.
Breadboard Canvas Reference Manual
The Breadboard Canvas is a replaceable and removable prototyping surface for the Analog
Discovery Studio. The bulk of the Breadboard Canvas consists of 2 regular sized breadboards
and three power rails. At the top of the board, two small breadboards contain the power access
pins for the power supplies, and pin breakouts for the included I/O. Two switches, LEDs, and
buttons are integrated into the Breadboard Canvas for convenience. The power supply access
pins can be switched on and off via the power supply switches, and the status is indicated by
the power indicator LEDs. The Breadboard Canvas is included with the Analog Discovery Studio.
Mechanical Design
The Breadboard Canvas is designed to connect to the Analog Discovery Studio via standoffs.
Magnets are located within each of the holes that the standoffs slot into in order to hold the
Canvas in place. The Breadboard Canvas can be removed from the Analog Discovery Studio and
swapped out with other canvases.
Warning! Do not swap out Canvases while the Analog Discovery Studio is turned on.
Breadboards
The Analog Discovery Studio Breadboard Canvas has two regular‐size breadboards and three
power rails mounted to the canvas surface.
Power Supplies
Each of the Analog Discovery Studio's power supplies, both variable and fixed, are connected to
the canvas, accessible via the power supplies breadboard.
The power access pins for the variable supplies, labeled V+ and V‐, are connected to the Analog
Discovery Studio's programmable power supplies. They can be programmed to voltage levels
from 1 to 5V (V+) and ‐1 to ‐5V (V‐) through the use of WaveForms' Power Supplies instrument.
Four fixed supplies are available, +12V, ‐12V, 5.0V, and 3.3V.
The power access pins can be enabled or disabled via the set of four switches adjacent to the
power supplies breadboard.
Green status LEDs, associated with each supply, turn on when power is available on that pin
(when the supply is enabled, and the ADS is turned on).
Since each power supply is sourced directly from the Analog Discovery Studio, the minimum
and maximum current and power available for each supply depends on the Analog Discovery
Studio's specifications. See the Analog Discovery Studio Specifications for more information.
Built‐in Components
The Analog Discovery Studio Breadboard Canvas features a variety of common components
which can be used within a circuit under test.
Each of the components described in this section is accessed via pins on the small breadboard
adjacent to SW2, referred to as the Built‐in IO Breadboard.
User Switches
Two switches are available on the Breadboard Canvas. When switched to the “On” position
(switched away from the breadboard surface), they provide a connection between the 5.0V
power rail and the corresponding pins (SW1, SW2) on the Built‐in I/O Breadboard. The 5.0V
power rail must be enabled to use the buttons.
A circuit diagram detailing how the switches are connected to the Built‐in I/O Breadboard can
be seen below.
User Buttons
Two user buttons are also available. When pressed, they provide a connection between the
5.0V power rail and the corresponding pins (BTN1, BTN2) on the Built‐in I/O Breadboard. The
5.0V power rail must be enabled to use the buttons.
A circuit diagram detailing how the buttons are connected to the Built‐in I/O Breadboard can be
seen below.
User LEDs
Three light emitting diodes, each of a different color, red, green, and yellow, are available on
the Breadboard Canvas. These LEDs can be controlled by providing power to the corresponding
pin on the Built‐in I/O Breadboard.
A circuit diagram detailing how the LEDs are connected to the Built‐in I/O Breadboard can be
seen below.
