Analog Discovery Canvas Reference Manual

The Analog Discovery Canvas is a replaceable and removable prototyping surface for the Analog Discovery Studio that can also be connected to the Analog Discovery to easily switch designs between devices without having to rewire or reassemble the design. The Analog Discovery Canvas provides 2 full solderless breadboards, a 2×15 header for connecting to an Analog Discovery, a 2×10 header for connecting to an Analog Discovery Studio, 4 solderless breadboards with access pins to inputs and outputs, 5 LEDs for power supply indication, 4 power switches, and 2 pin headers for 1+, 2+, W1, and W2 signals.

Mechanical Design

The Analog Discovery 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 Analog Discovery 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.


The Analog Discovery Studio Canvas has two regular-size breadboards and two power rails mounted to the canvas surface. There are also 4 breakout solderless breadboards for mapping I/O from either the Analog Discovery Studio or an Analog Discovery 3. Please note, if you do not have either an Analog Discovery Studio or Analog Discovery 3 plugged into the Analog Discovery Studio Canvas, the I/O connections on the four breakout solderless breadboards are not functionally connected to anything.

Analog Discovery Studio Outputs

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.

Shared Digital 1

The Shared Digital 1 breakout breadboard offers three connection points for ground, one for External Trigger 1 (TRIG 1/T1), and individual points for Digital I/O 0 (DIO 0) through Digital I/O 7 (DIO7).

Shared Digital 2

The Shared Digital 2 breakout breadboard offers three connection points for ground, one for External Trigger 2 (TRIG 2/T2), and individual points for Digital I/O 8 (DIO 8) through Digital I/O 15 (DIO15).

Analog Discovery I/O

The Analog Discovery I/O breakout breadboard offers four connection points for ground, as well as connection points for Oscilloscope Channel 1 (1+ and 1-), Oscilloscope Channel 2 (2+ and 2-), Wavegen Channel 1 (W1), Wavegen Channel 2 (W2), V+ and V-.
