Board size: 50mmX37mm Finished Size: 50mmX37mmX17mm (length X width X height maximum position size, contains copper foot height) Instructions: 1. The first test should be a fully charged battery. 2. Connect the battery to be tested positive to positive input, a negative input to the negative, can not be reversed (with load reversal may damage the circuit)! Load connected to the output of the positive and negative output, to work through the tester micro USB power supply (not available desktop or laptop USB powered), then the battery voltage. 3. Direct start test need only one press of the “OK” button, the tester can automatically develop an appropriate termination voltage of the battery full charge voltage, and will start flashing after the test three times. Need to develop artificial termination voltage only when the battery voltage display state by pressing “+” or “-” buttons to modify the termination voltage display beginning with P, behind the representative voltage resolution 0.1V, set up after pressing the “OK “start testing. 4. After the start of the test the tester will control the load of the electronic switch is turned on, the test data shows that the process will release capacity (Ah), current discharge current (A) and battery voltage (V) between the wheel was. When the battery voltage reaches the set cut-off voltage, load control switches off the tester display data stays in capacity (Ah) and above and the corresponding indicator flashes quickly together, now displays the actual capacity of the battery is discharging capacity, about the press “OK” to terminate flashing allows stable data display, press again “OK” button to return to the power-on state can just replace the battery test the next section …… Error codes and their meanings: Err1: battery voltage is above 15V Err2: battery voltage is lower than the termination voltage Err3: Battery can not afford to load or discharge current line too much resistance Err4: overcurrent (current exceeds 3.1A) Err5:Improper use or incorrect wiring has caused the device to be burned out and cannot be used (current sampling or control switch MOS burned out). Note: Use the resistance of the discharge process, resistive load will seriously heat, please pay attention to safety! This circuit voltage in order to improve the measurement accuracy, specially designed DC bias, when the terminal displays nothing then a small voltage does not affect the actual measurement, if you are shorting the input terminals (absolute 0V) will show 0 No retail package Quantity:1Pc Due to the difference between different monitors, the picture may not reflect the actual color of the item.

Out of stock74HC595 Serial to Parallel Shifting IC
[Logic Gates IC] DESCRIPTION:- The 74HC595N is a simple 8-bit shift register IC. Simply put, this shift register is a device that allows additional inputs or outputs to be added to a microcontroller by converting data between parallel and serial formats. Your chosen microprocessor is able to communicate with The 74HC595N using serial information then gathers or outputs information in a parallel (multi-pin) format. Essentially it takes 8 bits from the serial input and then outputs them to 8 pins. This small DIP packaged IC contains an 8-bit, serial-in-parallel-out shift register that feeds an 8-bit D-type storage register with parallel 3-state outputs. Pin Configuration:- Pin Number Pin Name Description 1,2,3,4,5,6,7 Output Pins (Q1 to Q7) The 74hc595 has 8 output pins out of which 7 are these pins. They can be controlled serially 8 Ground Connected to the Ground of the circuit 9 (Q7) Serial Output This pin is used to connect more than one 74hc595 as cascading 10 (MR) Master Reset Resets all outputs as low. Must be held high for normal operation 11 (SH_CP) Clock This is the clock pin to which the clock signal has to be provided from MCU/MPU 12 (ST_CP) Latch The Latch pin is used to update the data to the output pins. It is active high 13 (OE) Output Enable The Output Enable is used to turn off the outputs. Must be held low for normal operation 14 (DS) Serial Data This is the pin to which data is sent, based on which the 8 outputs are controlled 15 (Q0) Output The first output pin. 16 Vcc This pin powers the IC, typically +5V is used. Features :- 8-bit, Serial In – Parallel out Shift register Operating Voltage: 2V to 6V Power Consumption: 80uA Output source/sink current: 35mA Output Voltage is equal to Operating voltage Minimum high-level Input Voltage: 3.15V @(Vcc=4.5V) Maximum low-level Input Voltage: 1.35V @(Vcc=4.5V) Can be easily cascaded with more IC to get more outputs Maximum Clock Frequency: 25Mhz @4.5V Available in 16-pin PDIP, GDIP, PDSO packages Where to Use 74HC595 IC:- The 74HC595 is an 8-bit Serial In – Parallel Out Shift Register, i.e. it can receive (input) data serially and control 8 output pins in parallel. This comes in very handy where do not have enough GPIO pins on our MCU/MPU to control the required number of outputs. It is often used in projects where relatively a large number of LED's has to be controlled through the Microcontroller. It can also be used to interface LCD screen since they can acts as the data bit for the LCD displays. It can also be used to control 5V loads like relays through a 3.3V microcontroller since the high-level voltage is only 3.15. So if you are looking for an IC to save on your GPIO pins on the Microcontroller then this IC might be the right choice for you. How to Use a 74HC595 IC:- The 74HC595 shift register is commonly used with microcontrollers or microprocessors to expand the GIPO functionalities. It requires only 3 pins connected to the MCU, which are Clock, Data and Latch. It has a wide operating voltage from 2V to 6V. An application circuit of the IC is shown below: Package Includes:- 1 x 74HC595 IC
