— | The digital voltmeter-ammeter is designed to measure the DC voltage and current of the connected power source. The module can be used in power supplies that require visualization of output parameters. It can also be used to measure voltage and current readings within a circuit of devices. The module consists of two seven-segment red indicators. The voltage measurement range is from 0 to 99.9 V, and the current is from 0 to 9.99 A. The accuracy of the device readings is ± 1%. The measurement update rate is about 200 ms/time. This voltmeter-ammeter features a built-in shunt, which eliminates the need for an external shunt to measure current. The meter board has 5 pins: red wire: external device current measurement 0 - 9.99 A black wire: "ground" yellow thin wire: external device voltage measurement 0-100 V red thin wire: power supply of the device with a voltage of 4.5 - 30 V black thin wire: "ground" There are two ways to connect a digital voltmeter-ammeter: If the voltage of the measured power source is in the range from 4.5 to 30 V and has a common wire with the meter, then the device can be connected to its power supply. If the voltage of the measured source is higher than 30 V, it is necessary to use an external power supply with a voltage of 4.5 to 30 V to power the device. This meter is sold already calibrated. If necessary, calibrate the device, you need to use two tuning resistors. Using the I_ADJ potentiometer, the accuracy of the current measurement is adjusted, and the variable resistor V_ADJ changes the accuracy of the DC voltage. | 17.5 | — | — | 1 PC. | — | — | — | — | — | — | — | — | |||||||

— | The TDA8932 is a high quality, single channel, low frequency D-class amplifier. To date, the use of pulsed audio frequency amplifiers has greatly expanded. Thanks to this, this module can be used in speakers, home theater, car speakers, etc. The amplifier board has a small size and a wide supply voltage range, so it can also be used in portable speakers. The module is designed on the TDA8932 chip. The microcircuit has 32 outputs and is made in the SO32 package. The TDA8932 is a powerful class D amplifier. The microcircuit has DMOS (Diffusion Metal Oxide Semiconductor) transistors that act as output switches. The power rating of the amplifier is 35W into an 8 ohm load. The maximum output current of the module is 8 A. The conversion frequency of the module is 320 kHz, which provides an extremely low distortion factor (less than 0.1%). The efficiency of the module is over 90%. Thanks to all these advantages of the amplifier, it is capable of producing good sound quality. Also, the module has protection against: short circuit (short circuit) and overheating. The TDA8932 amplifier board has 6 pins: IN+: input signal IN-: common wire of the connected device OUT+: output signal OUT-: speaker common wire POWER+: Amplifier supply voltage POWER-: "ground" Power is supplied from the power supply or other external power source. The power supply voltage range of the amplifier is 10 to 30 V, but 12 to 24 V is recommended. | 13 | — | — | 1 PC. | — | — | — | — | — | — | — | — | |||||||
