The adapter card adopts imported MOS tube to switch on and off to ensure the effectiveness of the switch. The adapter card uses LEDs to display the working voltage of the supply in real time. The adapter card adopts multi-layer technology to ensure that the board will not be hot when the is in high current. The synchronization switch is added to realize the function of switching on and off synchronously with the main supply.

Description The MAX7219CNG is a compact, serial inputoutput common-cathode display driver that can interface microprocessors to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. Included on-chip are a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM that stores each digit. Communication with the MAX7219 is achieved through a convenient 4-wire serial interface supports SPI. Individual digits may be addressed and updated without rewriting the entire display. Only one external resistor is required to set the segment current for all LEDs. The IC also includes a 150A low-power shutdown mode, analog and digital brightness control, a scanlimit register that allows the user to display from 1 to 8 digits, and a test mode that forces all LEDs on. This device comes in a 24-pin DIP package. Features 10MHz Serial Interface Individual LED Segment Control DecodeNo-Decode Digit Selection

The supply board is equipped with LED voltage display, which can display the voltage of the main supply in real time. The floppy drive 4PIN is connected to the main supply and can be switched on and off synchronously. Press the white button to turn on the switch. When you plug in the cord, press the switch, the three-color LED flashes, and the LED display shows the voltage.

0.96" Blue 128X64 OLED LCD LED Display Module For Arduino IIC I2C Communicate DC 3V-5V SPI Serial Module Specifications: High resolution: 128 * 64 Viewing angle:> 160 ° Supports many control chip: Fully compatible with Arduino, 51 Series, MSP430 Series, STM32 / 2, CSR IC, etc. Ultra-low power consumption: full screen lit 0.08W Voltage: 3V ~ 5V DC Working Temperature: -30 c ~ 70 c Module Size: 27.0MM * 27.0MM * 4.1MM I2C/IIC Interface, need 2 IO only.

Using the module:Connect micro USB cable for power, or 5V DC to pads marked IN+ and IN- on the left-hand side of the module Connect cell to charge to B+/B- pads on the right-hand side of the module. A load (something for the battery to power) can be connected to the OUT+/OUT- pads on the right-hand side Important! Disconnect load when charging The red LED indicates charging in progress, the green LED indicates charging has finished. Never charge your battery at a rate greater than 1C. 2. It is better thanthe charging current is 37% of the battery capacity. If you charge the battery of 1000mAh, acurrent of 400mAh is enough. 3. The connection wire should not be too thick. 4. Make sure the connect point is good. 5. If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is a protection function, auto-subtract the charging current to avoid burn damage to thechip. 6. NO Reverse polarity.Features:Led indicator: red is charging Green is fully charged. Current Protection: Yes Inversed polarity: NO. Use mature charging chip TP4056 for simple peripheral circuits, good protection performance, and high charging accuracy. Fully machinery automated processing, all patch parts manufacturing.
