Frequently Asked Questions

Q: Are these development board modules compatible with Arduino and ESP32?

A: Yes! The vast majority of our display modules, ICs, and breakout boards are designed to work seamlessly with popular platforms including Arduino (Uno, Nano, Mega), ESP32, ESP8266, and Raspberry Pi. Each product listing includes pinout details and compatibility notes to help you get started quickly.

Q: What is the difference between I2C and SPI OLED display modules?

A: I2C OLED modules (like our 0.96" I2C OLED Display Module) use just 2 data lines (SDA & SCL), making them great for projects with limited GPIO pins. SPI modules (like the 0.91" SPI SSD1306 OLED) use more pins but offer faster data transfer rates, which is beneficial for frequently refreshed displays.

Q: Can I use the PMOLED transparent display in wearable or portable projects?

A: Absolutely. The 1.5" Transparent PMOLED Display is specifically designed with DIY wearables and compact portable devices in mind. Its transparent panel and SPI interface make it an eye-catching choice for smartwatches, HUDs, and custom enclosures.

Q: What are ferrite core inductors used for in maker electronics?

A: Ferrite core inductors, such as our 10-Pack Adjustable Ferrite Core Inductor Coils (13–34µH), are used in RF tuning circuits, noise filtering, power supply designs, and impedance matching. The adjustable core allows you to fine-tune inductance values for precise performance across 25–100MHz frequency ranges.

Q: Do you sell components in bulk or multi-packs for lab stocking?

A: Yes! Many items in our Development Boards & Modules collection are available in convenient 10-packs, including our PT2399 audio ICs, ferrite inductors, RGB keyboard LEDs, and SMA connectors. Multi-packs offer better value per unit and ensure you always have spares on hand for your projects.
