Frequently Asked Questions
Q: What voltage levels are supported by the relay modules and boards in this collection?
A: Our modules and boards cover a wide range of operating voltages. For example, the 1-Channel Relay Module supports 3.3V, 5V, 12V, and 24V control signals, making it compatible with virtually all popular microcontrollers and single-board computers. Always check the individual product page for exact voltage specifications before connecting to your circuit.
Q: Are these modules compatible with Arduino, Raspberry Pi, and ESP32?
A: Yes! The vast majority of modules and boards in this collection are designed to be platform-agnostic. They use standard I²C, SPI, UART, or GPIO interfaces supported by Arduino, Raspberry Pi, ESP32, STM32, and other popular development platforms. Datasheets and pinout details are available on each product page to help you get started quickly.
Q: What is a DC-DC buck converter module and when do I need one?
A: A DC-DC buck converter steps down a higher input voltage to a lower, stable output voltage with high efficiency — no excess heat like a linear regulator. Our 12V to 5V DC-DC Buck Converter Module is ideal for powering 5V microcontrollers or USB devices directly from a 12V car battery or power supply, making it perfect for automotive, robotics, and embedded projects.
Q: Which display module is best for a small microcontroller project?
A: For compact builds where space and power consumption matter, the 1.3″ OLED Display Module (128×64, SSH1106) is an excellent choice — it's bright, sharp, and draws very little current. If you need colour graphics, consider the 1.8″ 128×160 TFT LCD Display Module ST7735S, which delivers a full-colour 128×160 pixel display over SPI at 3.3V.
Q: Do you sell modules suitable for RF and software-defined radio (SDR) applications?
A: Absolutely. Our 10kHz–6GHz Low Noise Amplifier (LNA) Module provides 20dB of gain across an ultra-wideband frequency range and is specifically designed to complement SDR receivers, improving sensitivity and signal clarity for radio enthusiasts and RF engineers alike.
