Visit DigiKey at Maker Faire Rome 2025 for hands-on demos of Arduino, Adafruit, Raspberry Pi, & other cutting-edge new technologies, plus exclusive giveaways.

The Raspberry Pi 500+ features a mechanical RGB keyboard, upgrades memory to 16GB, and includes a pre-loaded 256GB SSD with the latest Raspberry Pi OS.

In this technical post, we explore the widely used CH340 IC from WCH, a popular USB-to-serial converter.

In this post, we measure the BMP280 barometric pressure sensor in Normal mode and Forced mode using the Nordic Power Profiler Kit II (PPK2).

Learn how dynamic and planar magnetic drivers create sound using magnets, diaphragms, and current.

The UNIHIKER K10 is now fully compatible with major programming platforms.

As Internet of Things (IoT) applications continue to evolve, developers using the ESP32 series often face challenges such as congested 2.4GHz bands, data transmission bottlenecks, and inefficient multi-device collaboration.

DFRobot’s DAC module selection guide, dividing modules into 0-2.5V/VCC, 0-5V/10V, 4-20mA categories. It details each product’s SKU, chip, channels, I/O, resolution, accuracy, features, includes functional diagrams, helping choose the right one.

This guide compares FireBeetle V1 vs V2 (ESP32/ESP8266/Arduino versions), breaking down key differences in features, hardware/software compatibility to help pick the best for smart home/IoT.

A comprehensive comparison of pH sensors tailored for various applications from Arduino enthusiasts to industrial monitoring.

When working on the UNIHIKER K10 AI vision recognition project, we often need to recognize our own face or point the camera in a different direction. However, since the K10's camera is fixed on the board, this can be difficult. To solve this, we can use a 24-pin FPC Extension Board and an FPC cable.
