The W5500 Ethernet Module is a high-speed SPI to Ethernet Module interface board powered by WIZnet's W5500 Hardwired TCP/IP embedded Ethernet controller IC.
This PZEM-004T V4 is a multi-function AC power monitor module used for measuring the AC voltage, current, active power, frequency, power factor and active energy via a non-invasive Current Transformer(CT) and TTL serial communication.
The PCA9306 module is a two-way I2C/SMBus voltage-level translator using the PCA9306 IC. This PCA9306 module is built to connect low-voltage controllers like 1.0 - 3.3V with higher-voltage devices up to 5V.
The BQ27220 is a high-precision low-power fuel gauge IC manufactured by Texas Instruments. The BQ 27220 device uses the Compensated End-of Discharge Voltage (CEDV) algorithm to monitor the battery parameters.
The L4941 is a 5V low dropout positive voltage regulator. It can regulate the output voltage even when the input voltage is only slightly higher than the output voltage. This is beneficial in battery-operated systems where maximizing battery life is crucial.
The NCP3170 is a synchronous buck regulator with integrated switching elements. It has a wide Input Voltage Range from 4.5V to 18V and it can deliver up to 3A output current. The NCP3170 uses current mode control for fast transient response and easy loop compensation.
The TDA7293 is a powerful class AB audio amplifier IC suitable for high-quality audio systems. The TDA7293 features a DMOS power stage, which offers high efficiency and low distortion. The TDA7293 can deliver up to 100 watts of power with an 8-ohm load.
The LA4440 is a high-performance, dual-channel audio power amplifier IC manufactured by Sanyo. It is a low-cost cost widely used audio amplifier IC. Once was one of the most popular choices for car stereos and portable boomboxes.
