Enjoy short circuit protection, indicated by the red LED. The (protected) voltage can be selected using a jumper (+5V or +3.3V). It can be powered by the mini USB (Power) connector, or this connector can be used as a breakout in your experiments. The +3.3V is regulated on the board itself. Switch to a custom supply when the +12V and -12V rails are needed as well (these are unprotected voltages).

It provides a clear separation of input (at the bottom) and output (at the top). Handy for (low-voltage) TTL, Arduino, ESP32, ESP8266 and LVCMOS experiments. Also for vintage computer experiments where an 8-bit bus is involved. Two parts are always ready to use: a button and a LED (with resistor).

All signals of the extension interface can be bridged using jumpers. For example: the four high-nibble input-bits can be tied to the output when they are not used on the breadboard. Super Breadboards can be chained vertically to do larger experiments.

Optionally, an 8-bit Workbench™ can be attached at the top. With this you have an annotated 8-bits binary LED display. It talks hexadecimal and octal. A clicky Digitast action-button provides a properly debounced signal for use with microprocessors. With it you can further learn about logic and see how number systems work. For binary data-input, a Binary Keyboard can be attached at the bottom. This provides a joyfull toggle experience for 8-bit data input.

Extend and combine this Super Breadboard with our other kits to learn and do (vintage) computer experiments. Visit our store to get more information on those products. A discount is applied when you order a combination of these kits that connect together.

- Shipping is tracked (you receive the tracking number), unless impossible to your country.

- For USA: package can be tracked with USPS as soon as it is in your country. USA shipping rates include all import duties, which are paid by me (the seller).

- No insurance, my experience is this is a farce anyway.

- Item ships within 3 business days (unless the item is a pre-order campaign, check its duration and lead time).

- Delivery is usually done within 10-15 business days, but may rarely take 4 weeks.
