Learn, explore, combine!
Pozitrum PoziKit is a safe, easy-to-set-up learning kit that teaches electronics and coding with real parts from the very first step.
Every child one day wonders what is inside their toy and wants to open it up.
Most do, and find a green board, tiny grey and black parts, and colourful wires.
After a while, they close the lid because they cannot make sense of what they see.
We set out so that this curiosity never fades.
Real parts, easy start.
Technical
Every block contains a real sensor of the kind used in everyday devices. Learners discover not only the code but also how that sensor works.
Practical
Connect, learn, build. No fiddling with wires, libraries or pin settings; nothing plugs in backwards, no module burns out, and the excitement to learn stays.
Free
Our learning content is free and open to everyone. Projects are not tied to a predefined path; the only limit is imagination.
Connect, build, change!
Preparation such as wiring, libraries and pin settings has been made simple.
- STEP 1
Connect
With a PizzaCable, a sensor block connects to any PizzaSocket on the P-Board. When you hear the “click”, the physical connection is secure.
- STEP 2
Build
PoziTag introduces the block; the P-Board supplies the right voltage and sets up the library and pins. Learning and building start right away!
- STEP 3
Change
With free and open learning content, students move from concept to project. They can change the code or the block and see for themselves what happens. The only limit is imagination.
P-Board
P-Board is the station where all blocks connect and your code runs.
5 PizzaSockets
Connects up to five blocks at once. The P-Board recognises each block and supplies the right power; when a block is removed, its socket switches off on its own.
Built-in OLED display
Sensor readings and messages can be shown on the on-board display, so no separate display module is needed.
Wi-Fi and Bluetooth
With wireless support, projects can talk to other devices without cables.
Three programmable buttons
The blue, yellow and red buttons can be used from the very first lesson; what each one does is decided by your code.

Real sensors, real curiosity!
Every PoziKit sensor block shares the same structure: a screw-on lid, a real sensor, a PoziTag ID card, a PizzaSocket and an outer case.
Everyday Electronic Parts
We use real modules of the kind found in parking sensors, motion-activated lights, TVs and phones.
PoziTag
Sensor information is stored on the PoziTag ID card in the block. The sensor is left unchanged; only setup gets easier.
Screw-on Lid
Open the screw-on lid on top of each block to examine the sensor inside.
PizzaSocket
A single socket carries both data and power. No tangled wires, no trouble.
Plugs in one way, works the first time.


- One Connection: Power and data share the same socket.
- Safe Plug-in: The insulated body ensures safe contact.
- One Way: The socket cannot be plugged in backwards.
- Smart Protection: No power until the block is recognised.
For every curious mind, at any age and any level.
Students and Families FROM PRIMARY SCHOOL
Building their first project with their own hands, students see for themselves what their code changes. Younger learners use it safely with a parent alongside.
Teachers and Schools CLASSROOM
No time lost on setup; the lesson starts straight with the topic. Free learning content built around the lesson plan lets learning continue at home.
Makers and Engineers ADVANCED
With real sensors and real code, prototyping is fast, without the hassle of wiring and setup. Every project built with the kit is the first step towards something new.
Five kits from white to black, one ecosystem.
As curiosity grows, so does the kit. There is no need to start over to move up a level; an upgrade kit adds new blocks, and none of the blocks you already have go to waste.
- PoziKit White
6 blocks
First projects with light, sound and touch
- PoziKit Blue
12 blocks
Reading a sensor and producing an output
- PoziKit Yellow
18 blocks
Designing systems with multiple parts
- PoziKit Red
24 blocks
Devices that log data and take control
- PoziKit Black
30 blocks
Complex systems that sense position and motion
Our learning content is free and open to all.
Each topic starts with a concept, continues with a guided project using annotated code, and ends with the student solving a new problem on their own.
We came to invent, not to watch!
Pozitrum is a technology start-up that develops hardware, software and learning content to teach electronics and software with real parts.
Our Mission
To teach electronics and coding safely, clearly and lastingly, from the very first step.
Our Vision
Tomorrow’s defence and space technologies begin with today’s curiosity. To be the learning infrastructure that nurtures this curiosity without interruption, from primary school to university.
We only make the first steps easier; the curiosity is still real!
