Protonema stamps provide various functions for building projects.
The Raspberry Pi Pico stamp allows for experimentation with microcontrollers using the RP2040. All I/O lines are available, plus a higher precision 3.0 volt reference for analog to digital conversion.
The LED Matrix stamp is an 8x8 LED matrix that can be used to display small images and create simple games. It is connected to a processor stamp using multiplexed GPIO lines.
The prototyping stamp provides a breadboard-style layout for quickly and easily soldering through-hole components to create custom stamps.
The LED Display stamp is a 4 digit seven-segment LED display that can be used to display small numeric values. It is connected to a processor stamp using multiplexed GPIO lines.
The quad 3.5mm jack stamp allows you to connect 3.5mm cables to your project, for example, when prototyping Eurorack synth modules. Two jacks are labelled for inputs, and two jacks are labelled for outputs.
The dual potentiometer stamp allows you add two variable resistors to your project.
The Intelligent Display stamp is a 4 character smart display that can be used to display small text messages and custom graphics. It is connected to a processor stamp using a simple serial protocol.
The sliders stamp two slide-style variable resistors to your project, each with a LED.
Provides eight LED indicators to monitor digital signals when experimenting with digital logic.
Use these as a starting point for creating your own stamps.
