SKU: SF-PRT-15217

The SparkFun LiPo Charger Plus is the souped-up power option in the SparkFun line of single-cell lithium polymer (LiPo) battery chargers. With this iteration, we've changed the input charge connector to USB-C and provided charge rate selection as well as optional thermal protection. Charge, power...

SKU: AF-372 · MPN: 372

An epoxy-coated precision NTC thermistor with a 10kΩ resistance at 25°C and ±1% accuracy. The resistance decreases as temperature rises and increases as it cools, making it straightforward to measure temperature with a simple voltage divider circuit. The epoxy coating allows the thermistor to be...

SKU: SF-SEN-00250

10K thermistor with a negative temperature coefficient. Good choice for temp-sensing applications when you need a reliable NTC thermistor. Vishay part #: NTCLE100E3103JB0 Note: You get only one thermistor. Document:  Datasheet Bildr Tutorial

SKU: LB-10K-5

A pack of five NTC thermistor temperature probes, each with a 1-metre wire lead for remote temperature sensing. These 10 KΩ (at 25°C) NTC sensors are sealed in a cylindrical metal probe for durability and are suitable for measuring temperatures from −30°C to +110°C. NTC thermistors decrease in r...

SKU: TB-RN3436

A 1 kΩ NTC (negative temperature coefficient) thermistor in a 5 mm radial dipped-epoxy package. The resistance decreases as temperature increases, making it suitable for temperature sensing, thermal compensation, and monitoring applications. Rugged ceramic construction with tinned copper leads fo...

SKU: TB-RN3444

A 100 kΩ NTC (Negative Temperature Coefficient) thermistor in a radial dipped-epoxy package. These ceramic sensors change resistance rapidly with temperature, making them ideal for temperature measurement, compensation, and thermal protection circuits. Key Features NTC Ceramic Construction – R...

SKU: TB-RN3442

A 47 kΩ NTC (Negative Temperature Coefficient) thermistor in a compact 5 mm radial package. NTC thermistors decrease in resistance as temperature rises, making them ideal for temperature sensing, thermal protection, and compensation circuits. Dipped in epoxy for durability, this through-hole com...

SKU: AF-1570 · MPN: 1570

A compact 3.7 V lithium-ion polymer (LiPo) battery with approximately 100 mAh capacity (0.4 Wh). Thin, lightweight, and powerful, this cell is suited for small wearable projects, IoT devices, and compact electronics where space is limited. The battery comes pre-wired with a genuine 2-pin JST-PH ...

SKU: LB-00254

A 3.7 V lithium-ion polymer (LiPo) battery with a generous 2500 mAh capacity (~10 Wh). Thin, lightweight, and fitted with a 2-pin JST-XH connector for reliable connections to compatible chargers and development boards. Includes built-in protection circuitry to guard against overcharging, over-di...

SKU: AF-4755 · MPN: 4755

The Adafruit Universal USB/DC/Solar Lithium Ion/Polymer Charger (bq24074) charges 3.7V/4.2V LiPo or LiIon batteries from virtually any power source — USB Type-C, DC adapter, or solar panel — with a wide 5–10V input range. Its near-MPPT solar tracking automatically draws the maximum current availa...

SKU: AF-576 · MPN: 576

Put a temperature meter anywhere with this very handy display. This panel meter displays the temperature of the attached waterproof 1% thermistor in °C. It does require a DC voltage to run, at 4.5-30VDC. It has reverse polarity protection in case you swap the power leads by accident. To use, sim...

SKU: MR-TEMP

The Temperature Cubelet contains a tiny thermometer (actually, a thermistor) that detects temperature. It’s calibrated to output a 0 in freezing conditions and 255 in hot, sunny conditions of about 35C.Cubelets are magnetic blocks that can be snapped together to make an endless variety of robots....

SKU: AF-519 · MPN: 519

Measuring stretch forces isn't easy - unless you have some conductive rubber cord! This cord is 2mm diameter, and 1 meter long, made of carbon-black impregnated rubber. Usually this material is used for EMF gasketing, but its also very fun to play with.In a 'relaxed' state, the resistance is abou...
