Arduino

About 75 boards across every Arduino generation: 5V Uno/Mega/GIGA, 3.3V MKR and Portenta, plus DFRduino and Bluno compatibles. Confirm the voltage rail before stacking any shield.

Boards · Arduino boards · 77 parts

Add-ons

About 270 add-ons across Pi HATs, Arduino shields, and FeatherWings. The same function — motor control, PoE, display — usually ships once per host connector family. Get the host board right first.

Other MCUs

Specialists: Teensy for high-clock audio and USB, Adafruit SAMD boards running CircuitPython or the Arduino IDE, proper STM32 eval kits, and the micro:bit classroom ecosystem. Schematik builds target ESP32, Arduino Uno, and Pico; come here when you have a specific reason to.

Pi Pico

The Raspberry Pi MCU line — Pico, Pico 2, and third-party boards on the same silicon — plus a deep bench of Pico-pinout displays, loggers, and radio modules that do nothing without a Pico plugged in.
