About the 8 switch array PCB

8 switch array is an open source PCB design by BeeHive-org, published on GitHub under the MIT license. It is a 2-layer board measuring 45.5 × 48.5 mm, with 14 components from 5 distinct parts.

Other key parts include the 296-1600-5. By type, the board carries 12 connectors, 1 IC and 1 capacitor.

From the project

BeeHive: a flexible open hardware platform for behavioural experiments

In order to allow to use arbitrary type and number of simple tools such as low power electronics (LEDs, fans, etc) in experiments, a set of 8 switch arrays was developed. The 8 pin version utilizes a 74HC595 shift register, allowing to connect more components with less amount of pins. The power fed to the element being switched can vary from 5 to 12 volts.

An 8 switch array behaves exactly like a 74HC595 shift register but transistor switches allow bigger currents to flow through given loads

8 switch array: common questions

How big is the 8 switch array PCB?

The 8 switch array measures 45.5 × 48.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 8 switch array?

14 components, from 5 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the 8 switch array design files?

From the BeeHive-org/BeeHive repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the 8 switch array design in my own project?

Yes, under the terms of its MIT license, which BeeHive-org chose for the repository.
