Accurate timekeeping, even during power outages.

Most power banks will automatically turn off their USB ports when the power/current being drawn is lower than a certain value. This makes it impossible to...

Keep your power bank running with ultra-low power devices using the compact USB-C KeepAlive module, featuring automatic pulse technology to prevent automatic shutoff when powering microcontrollers, Raspberry Pi Picos, or other small electronics.

Keep your power bank from auto-shutting off with this pre-assembled USB KeepAlive adapter, designed to maintain power delivery for low-current devices like microcontrollers, Raspberry Pi Pico, and other USB-powered projects.

Never hunt around for another crystal again, with the Si5351A clock generator breakout from Adafruit! This chip has a precision 25MHz crystal reference and internal...

4017 Decade Counter/Divider CMOS IC (Complementary Metal-Oxide-Semiconductor) logic chips are popular due to their lower power consumption, wider range of power supply voltages (3-15V) than those offered by TTL (Transistor-Transistor Logic) and a reduced need for extraneous circuitry, simplifying the design process and reducing circuit board size.

The CD40106BE consists of six Schmitt-trigger circuits. Each circuit functions as an inverter with Schmitt-trigger action on the input. The trigger switches at different...

The SparkFun Servo Trigger is a small robotics board that simplifies the control of hobby RC servo motors. When an external switch or logic signal changes state, the Servo Trigger is able to tell an attached servo motor to move from position A to position B. To use the Servo Trigger, you simply connect a hobby servo and a switch, then use the on-board potentiometers to adjust the start/stop positions and the transition time. You can use a hobby servos in your projects without having to do any programming!

Build your own USB KeepAlive circuit to prevent power banks from auto-shutting off when powering low-current devices like Raspberry Pi Pico or microcontrollers with this DIY soldering kit featuring a 555 timer design.

This module features a fixed-gain, 38 kHz modulated IR sensor and a corresponding IR LED with oscillator circuit to make a tiny proximity sensor. This high-brightness version draws an average of 16 mA at 5 V and has a typical sensing range up to approximately 24 inches (60 cm).

Good stability and far more accurate than MCU internal oscillators.

This module features a fixed-gain, 38 kHz modulated IR sensor and a corresponding IR LED with oscillator circuit to make a tiny proximity sensor. This low-brightness version draws an average of 8 mA and has a typical sensing range up to approximately 12 inches (30 cm).

The sequencer allows you to connect up to eight outputs and control them in sequential patterns. Sequences that would take as long as 4 days to program without littleBits will only take you seconds!
