WHAT'S NEW TOP SELLERS QWIIC MICROMOD REDBOARDS THING+ TUTORIALS

While most microcontrollers only simulate an analog voltage using Pulse Width Modulation, this breakout board allows you to generate a true analog signal. The SparkFun MCP4725 Digital-to-Analog Converter (DAC) Breakout provides accurate, 12-bit analog voltage output via I2C and features onboard EEPROM to store settings even after power loss. This makes it a great choice for a wide variety of electronics projects where standard digital signals can't quite give you what you need.

To DAC, or Not to DAC

The ESP-VoCat is an AI voice interaction development kit built around the ESP32-S3, combining wireless connectivity, a circular touchscreen, microphone array, speaker, and battery support into a compact platform for developing voice-enabled and AI-powered devices. The ESP-VoCat is designed for applications such as AI assistants, smart speakers, interactive toys, desktop robots, and smart home controllers, and supports offline voice wake-up, sound source localization, and cloud-based AI services.

It's Cute & it Talks Back to You

The Benewake TF-NOVA LiDAR Distance Sensor is a compact, solid-state LiDAR sensor designed for obstacle detection, presence detection, and area ranging applications. Unlike conventional point-ranging LiDAR sensors, the TF-NOVA projects a 14° × 1° laser line, allowing it to detect objects across a wider horizontal area without mechanical scanning or multiple sensors. It provides a 0.1 to 14m measurement range with up to 900Hz measurement rates, making it well suited for robotics, autonomous platforms, industrial automation, and other applications where compact area detection is required.

Small Areas Require Precise Distance Data
