This real-time clock module (RTC) uses the DS3231 chip that integrates a crystal resonator and a temperature compensator, which improves the long-term accuracy of...

The Raspberry Pi is a great low cost computer with thousands of different uses but one thing it does not come with is a real-time clock. This means that every time you switch off your Raspberry Pi it forgets what the time is and you have to manually set it again next time you switch your Raspberry Pi on.

The Pico-RTC-DS3231 is a RTC expansion module specialized for Raspberry Pi Pico. It incorporates high precision RTC chip DS3231 and uses I2C bus for communication. More external sensors are allowed to be connected thanks to the stackable design.

Digital calipers are an absolute essential. Here at SparkFun we use them all the time. These premium calipers come with an extra battery and auto shut-off. Measurements can be taken in either metric or standard. The calipers are 6" in length and make a great addition to any tool set.

The real-time clock RTC breakout module employs the SD3031 chip with an integrated crystal oscillator and temperature compensator and a built-in 70-byte...

The Fermion: BLE Sensor Beacon has a built-in 11-bit ADC, Fermion version, and multiple I/Os that can be multiplexed to SDA/SCL while broadcasting over...

Are you still looking for a low cost thermometer? Did you get one? Aha! Here it is! This is a new waterproof digital thermometer with display. It is suitable for greenhouse, fish tank, swimming pool and other application scenarios which require temperature measurement. It is completely waterproof to a depth of one meter for long time. And it can continuously work for half the year with only 2 AG13 button cell.

This RTC module is specifically designed for the Raspberry Pi. It communicates with Raspberry Pi through I2C bus and includes a Maxim DS1307 on the board to keep a real time clock for a long time after the Pi has powered down. Just set a serial port, and you have a convenient way of online debugging using TTL. Supports Raspberry Pi B/A+/B+/2 model B/3 model B.

Ever wanted a simple way of activating your robot from across the room? We designed this remote controller to be as simple, small, and affordable so that for the majority of the projects you've built, you will no longer need to move constantly to swtich it on/off.

The SparkFun IN100 NanoBeacon Lite Board offers a 2.4 GHz wireless low energy BT beacon breakout with exceptional low power consumption features...

What's the difference between Pi and Arduino? We all know Raspberry Pi is a mini-computer running on Linux operating system; while Arduino is a microcontroller running on simple I/Os. Both of them focuses on very different areas. Compared with Arduino, the Pi gets much better computing performance.

This smart SMD tester is essentially a pair of multimeter tweezers. This allows you to troubleshoot circuits with small SMD parts without having to fumble with large probes or long wires. Test resistors, capacitors and diodes one-handed!

The RTC module is specifically designed for Raspberry Pi. It communicated with Raspberry Pi through I2C bus. There is a Maxim DS1307 and CR1220 button...
