The TP4056 1A Li-ion Lithium Battery Charging Module with Current Protection – Mini USB is a compact device designed to charge individual lithium ion (Li-Ion) cells that lack their own protective circuit, such as 16550s, with a single cell capacity of 3.7V and 1 Ah or higher. This battery charging module employs the TP4056 charger IC and DW01 battery protection IC to provide a charge current of 1A, which will cease upon completion of the charging process. https://robocraze.com/products/tp4056-lithium-battery-charging-board #PCB #TP4056 #battery

The Texas Instruments TPA3140D2 is a high-efficiency, Class-D audio power amplifier designed for driving bridged-tied stereo speakers with outputs up to 10 W per channel into 6 Ω or 8 Ω loads. With advanced EMI suppression technology, including spread spectrum control and a 1SPW modulation scheme, the TPA3140D2 ensures robust performance while minimizing electromagnetic interference. Operating within a wide supply voltage range from 4.5 V to 14.4 V, this amplifier eliminates the need for heat sinks due to its up to 90% efficient Class-D operation. Integrated SpeakerGuard™ protection features such as automatic gain limit (AGL), adjustable power limiter, and DC protection enhance speaker safety and audio quality. Additionally, the TPA3140D2 includes comprehensive protection against pin-to-pin, pin-to-ground, and pin-to-power short circuits, as well as thermal protection with auto recovery. The device offers four selectable fixed gain settings and supports both single-ended and differential analog inputs, making it suitable for a variety of consumer audio applications including televisions, wireless speakers, mini speakers, and USB speakers. The TPA3140D2 is available in a 28-pin HTSSOP package, ensuring ease of integration into compact designs.

This project uses an Arduino Mega microcontroller connected to 5 flexible sensors and a mini speaker with position and acceleration sensors to create an interactive device. It uses AMS1117 voltage regulators to provide regulated power, a CH340C for USB communication, and includes capacitors and resistors for circuit balance. Ideal for IoT and edge computing tasks. #referenceDesign #project #ArduinoMega #flexSensors #miniSpeaker #motionSensor #IoT #edgeComputing #reusable #module #Arduino #template
