 One of the key features of the Analog Discovery Studio is the versatility offered by the Canvas boards. Entire designs, demonstrations, and hands-on teaching tools can be swapped in and out with ease, taking advantage of multiple voltage lines and USB data lines provided by the Analog Discovery Studio. One of the key features of the Analog Discovery Studio is the versatility offered by the Canvas boards.

-On board microprocessors and systems present on canvases can be configured through the provided USB data lines, allowing for custom embedded labs that take advantage of the supplied voltage rails to measure data from different sensors. Variable voltage and dedicated +12V, -12V, +5V, +3.3V supplies and multiple ground lines are provided to support a variety of peripherals.+On board microprocessors and systems present on canvases can be configured through the provided USB data lines, accessible through the USB hub integrated into the Analog Discovery Studio, allowing for custom embedded labs that take advantage of the supplied voltage rails to measure data from different sensors.

-The Analog Discovery Studio has 10 power pins (pogo pins) that are located in the top center of the landing area to provide power to the loaded canvas. The two sets of 5 pogo pins have a 2.54 mm (100 mil) pitch and are each 2.25 mm in diameter. A slot in each of the corners is also provided for standoffs to magnetically attach the canvas to the Analog Discovery Studio. Digilent used 3/4 inch (19.05 mm) steel standoffs with a 1/4 inch (50.8 mm) outer diameter and a 6-32 thread. The screws used on the canvases to secure them to the standoffs are 6-32 x 0.250 inch (50.8 mm) machine screws. +The Analog Discovery Studio has 10 pins (pogo pins) that are located in the top center of the landing area to provide power and data to the loaded canvas.

-Trance widths extending from the pogo pins provided by the Analog Discovery Studio are dependent on the custom canvas copper weight and current usage. If using the same machine screws used by Digilent, the total thickness of the canvas should not exceed 2.36 mm. +Trace widths extending from the pogo pins provided by the Analog Discovery Studio are dependent on the custom canvas copper weight and current usage.
