Lithium Polymer LiPo Battery (3.7V, Single-Cell) Lithium Polymer LiPo Battery (3.7V, Single-Cell)
Lithium Polymer LiPo Battery (3.7V, Single-Cell) from ₹ 99.99 ₹ 199.00
We offer a wide range of single cell Lithium ion polymer (also known as 'lipo' or 'lipoly') batteries, that are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.2V. While the nominal voltage of the battery remains at 3.7V, which is also a safe voltage to store the battery at.  The batteries have come with either a 2-pin JST-PH connector or "no connector" and include the necessary protection circuitry. The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use), which means that the battery will cut-out when completely dead at 3.0V. It will also protect against output shorts. However, even with this protection it is important to use a LiIon/LiPoly constant-voltage/constant-current charger to recharge and at a rate of 2A or less (500mA is best). We suggest our Micro Lipo charger, which has a 100mA default rate. You can also set the Micro Lipo to 500mA rate for a faster charge. NOTE: We can provide custom LiPo batteries for BULK orders on demand.

Brass Rigid Motor Shaft Coupler (1 pc) from ₹ 99.99 ₹ 149.99
Couplings are devices used to connect two shafts together and are divided into two categories: Rigid and Flexible.Both are used for the purpose of transmitting power, rigid couplings being more limited in applications as compared to flexible couplings. Rigid couplings are used where shafts are already positioned in precise lateral and angular alignment. Their design does not allow for any misalignment between shafts, but are generally able to transmit more power than flexible couplings.  Tighten the set screws to fasten these couplings to your shaft. Set screws bite into the shaft to hold the couplings in place. All are lightweight, corrosion-resistant aluminum. Diameter: 9mm Length: 20mm

Platinum (PT100) RTD Temperature Sensor Amplifier - MAX31865 Platinum (PT100) RTD Temperature Sensor Amplifier - MAX31865 - ThinkRobotics.in
Platinum (PT100) RTD Temperature Sensor Amplifier - MAX31865 from ₹ 259.99 ₹ 599.00
The MAX31865 is an easy-to-use resistance-to-digital converter optimized for platinum resistance temperature detectors (RTDs). An external resistor sets the sensitivity for the RTD being used and a precision delta-sigma ADC converts the ratio of the RTD resistance to the reference resistance into digital form. The MAX31865's inputs are protected against overvoltage faults as large as ±45V.  For precision temperature sensing, nothing beats a Platinum RTD. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is actually a small strip of Platinum with a resistance of 100 ohms at 0°C, thus the name PT100 The MAX31865 handles all of your RTD needs, and can even compensate 3 or 4 wire RTDs for better accuracy. Connect to it with any microcontroller over SPI and read out the resistance ratio from the internal ADC. A 430Ω 0.1% resistor as a reference resistor on the breakout is used. We even made the breakout 5V compliant, with a 3.3V regulator and level shifting, so you can use it with any for For Arduino or microcontroller. NOTE: RTD sensor is optional! ● Integration Lowers System Cost, Simplifies Design Efforts, and Reduces Design Cycle Time Simple Conversion of Platinum RTD Resistance to Digital Value Handles 100Ω to 1kΩ (at 0°C) Platinum RTDs (PT100 to PT1000) Compatible with 2-, 3-, and 4-Wire Sensor Connections SPI-Compatible Interface 20-Pin TQFN and SSOP Packages ● High Accuracy Facilitates Meeting Error Budgets 15-Bit ADC Resolution; Nominal Temperature Resolution 0.03125NC (Varies Due to RTD Nonlinearity) Total Accuracy Over All Operating Conditions: 0.5NC (0.05% of Full Scale) max Fully Differential VREF Inputs 21ms (max) Conversion Time ● Integrated Fault Detection Increases System Reliability ±45V Input Protection Fault Detection (Open RTD Element, RTD Shorted to Out-of-Range Voltage, or Short Across RTD Element) Specifications Resources Datasheet Libraries Sample Code Tutorials
