The LD1117V33 is a low-dropout (LDO) positive voltage regulator with a fixed 3.3V output. With on-chip trimming providing ±1% output voltage tolerance and built-in current and thermal limiting, it's a reliable choice ...

SKU: AF-5188 | Brand: Adafruit

The Adafruit DS3231 Precision RTC with STEMMA QT connectors is a highly accurate I2C real-time clock featuring an integrated temperature-compensated crystal oscillator (TCXO). Unlike standard RTCs that rely on an exte...

SKU: AF-935 | Brand: Adafruit

The MCP4725 breakout board provides a 12-bit digital-to-analogue converter (DAC) over I2C. Send a digital value and the VOUT pin outputs the corresponding analogue voltage — ideal for generating waveforms, adjustable ...

SKU: DF-DFR0151 | Brand: DFRobot

The DS1307 Real Time Clock module developed by one of our designers: Waiman. The module comes fully assembled and pre-programmed with the current time (ok, so it's our current time - MST). The included Lithium co...

SKU: AF-5664 | Brand: Adafruit

Need to use multiple I2C devices that share the same address? The PCA9546 4-Channel STEMMA QT / Qwiic I2C Multiplexer lets you connect up to four same-address I2C devices with completely solderless wiring. Five JST SH...

SKU: SF-COM-16473 | Brand: SparkFun

The classic 555 timer/oscillator IC from Texas Instruments — one of the most versatile and widely used integrated circuits in electronics. With just a few external resistors and capacitors, it can generate timing dela...

SKU: SF-COM-15105 | Brand: SparkFun

This diode-transistor photocouplers consist of an LED, optically coupled to a high speed photodetector to transmit electrical signals between circuits while still isolating your system from higher voltages. The 6N137 ...

SKU: AF-2164 | Brand: Adafruit

The classic L7805 linear voltage regulator in a TO-220 package, capable of delivering a clean, regulated 5.0 V output (±2%) from an input voltage of 7–35 V. With built-in current limiting and thermal shutdown protecti...

SKU: AF-2166 | Brand: Adafruit

A low-dropout (LDO) 3.3 V linear voltage regulator based on the ST L4931 in a TO-92 package. With just 0.4 V dropout, it delivers a clean, regulated 3.3 V output from input voltages as low as 3.7 V — well suited for s...

SKU: AF-1875 | Brand: Adafruit

Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V de...

SKU: SF-COM-08636 | Brand: SparkFun

The MCP3002 is a 10-bit analog-to-digital converter (ADC) with a simple SPI interface, available in a breadboard-friendly 8-pin DIP package. Use it to add analog input capability to microcontrollers that lack an ADC, ...

SKU: SF-COM-00527 | Brand: SparkFun

The LM317TG is a three-terminal adjustable positive voltage regulator with an output range of 1.2V to 37V and up to 1.5A output current. Only two external resistors are needed to set the desired output voltage, making...

SKU: SF-COM-00315 | Brand: SparkFun

The SN754410 is a quad half H-bridge motor driver IC capable of driving DC motors, stepper motors, and other inductive loads. It accepts TTL 5V logic inputs and can drive motors from 4.5V to 36V at up to 1A continuous...

SKU: AF-3296 | Brand: Adafruit
