miniTesla

miniTesla is a solderless electronics prototyping system based on an ingenious spring connector originally developed by Philips in the 1960s. This connector provides mechanic as well as electric connectivity. We have further improved the original system by eliminating the need for carrier boards for discrete transistors, and by adding additional ways to connect components providing three layers of interconnectivity. We are also providing convenient interfaces to popular platforms such as Raspberry Pi and Arduino. For more details refer to our free manual.

8-pin DIP by miniTesla

Some of the most popular chips come in 8-pin, arranged as 2 rows of 4 pins, DIP packaging. Think about the famous 555 timer chip or dual-operational amplifiers such as the LM358. You can also find comparators (LM393) and audio amplifiers (LM386). You can put two optocouplers PC817 into the socket. Some microcontrollers such as the ATtiny85 also fit.

You are not limited to only inserting integrated circuits. If you do not want to bend the leads of a transistor you can put it into this socket. In fact, there is space for two transistors.

It is a very handy socket, and if you have larger...

DIY Toggle Switch by miniTesla

This board allows you to build a neat little toggle switch. Additionally to the printed circuit board, you will receive an M4 brass screw, an M4x20 mm long nylon hex spacer, a 3-hole long trace, and two M4 screws with nuts. You will also need three spring contacts (not included in this kit) to connect the switch to your circuit.

Mini Breadboard Breakout kit by miniTesla

A breakout board for a mini breadboard with 170 tie points, and 34 distinct connection groups (1-17 A and B). This is very convenient to connect integrated circuits or any other electrical component which you cannot directly clamp into the spring contacts but which fits into a breadboard.

This kit requires soldering. To solder the mini breadboard onto the PCB, first, remove the adhesive backing from the mini breadboard. Put the breadboard upside down on the table so that the exposed contact rows on the back are visible. Place the PCB with the central opening over the breadboard. Align the...

Mini Breadboard Breakout sub-board by miniTesla

A breakout board for a mini breadboard with 170 tie points, and 34 distinct connection groups (1-17 A and B). This is very convenient for integrated circuits or any other electrical component which you cannot directly clamp into the spring contacts but which fits into a breadboard.

This sub-board comes ready-made, meaning the mini breadboard is already soldered onto the PCB. If you want to solder it yourself you can purchase the cheaper Mini Breadboard Kit.

Rotary Switch 1-out-of-9 sub-board by miniTesla

This is a rotary switch that connects a common (COM) pin with one out of 9 pins. This is a through-hole component and thus this sub-board can only be used on the edge of a pegboard, either immediately above or below the pegboard.

Toggle Switch sub-board by miniTesla

Our toggle switch has three positions: left, middle, and right. The left switch position connects the middle pin to the left pin. The middle is a neutral position where the middle pin is not connected to anything. In the right position, the middle pin is connected to the right pin. You can use this toggle switch as a simple on-off switch, or as a selector between two alternatives.

2.1 mm Female Barrel Connector sub-board by miniTesla

The most widely used barrel connector is the 2.1 mm one. They are often used for low-voltage power supplies and wall adaptors. You will probably have several of these lying around from old or broken toys and other equipment. They make great power supplies for various projects. This sub-board allows you to easily connect them to the miniTesla system.

This one has a plug insertion detection, a switch that is closed and thus connected to the sleeve if no plug is inserted. Once a plug is inserted this switch opens. This is useful to automatically switch between battery operation, when no plug...

10k Ohm Potentiometer with Pushbutton sub-board by miniTesla

A potentiometer, or variable resistor, with three pins labeled CW, CCW, and wiper. The wiper moves between the CW (clockwise) and CCW (counterclockwise) endpoints and therefore the resistance between the wiper and the endpoints changes with the position of the potentiometer. The resistance between CW and CWW is a constant 10k Ohm.

Additionally, this potentiometer has a built-in momentary pushbutton by pressing down on the dial. When pressed the SW1 and SW2 pins are connected.

Header or Breadboard Connector (10 pins) by miniTesla

This board is particularly useful to interface with a breadboard. It has 10 pins and therefore 10 adjacent rows of a breadboard can be connected to. This is currently the only sub-board that has to be used on top of our spring contacts. The 10 pins are inserted into the breadboard. The holes attach to the top of the spring contacts. It is also recommended that you remove the adhesive backing from the breadboard to match the clearance below the header contacts.

Some components, such as integrated circuits, can nicely be inserted into a breadboard. This connector allows an easy interface to mix and...
