Control circuitry associated. A brief description: 1. The main chip: NE555; 2. Input voltage: 5V-15VDC. 5V power supply. The output current can 15MA around; 12V power supply, the output current can 35MA around; 3. The input current: ≥ 100MA; 4. The output amplitude: 4.2V V-PP to 11.4V V-PP. Different depending on the input voltage. The output amplitude will be different) 5. The maximum output current: ≥ 15MA(5V power supply. V-PP greater than 50% ≥ 35MA(12V power supply, V-PP greater than 50% Advantages: 1. The output with LED indication. There is no output straightforward(low LED volume, high LED off frequency is relatively low, the LED flashes) 2. The output level selectable frequency range. The output frequency is more continuously adjustable; LF file: 1Hz ~ 50Hz IF file: 50Hz ~ 1kHz High-frequency file: 1KHz ~ 10kHz HF file: 10kHz ~ 200kHz 3. The output duty cycle can fine-tune. Duty cycle and frequency is not separately adjustable, adjusting the duty cycle will change the frequency 4. The output frequency is adjustable; Period T = 0.7(RA +2 RB) C RA. RB is 0-10K adjustable; Low profile when C = 0.001UF; IF stalls C = 0.1UF; High-frequency file C = 1UF; HF stalls C = 100UF. So the frequency of the waveform buyers can own calculations. Note: Due to the difference between different monitors. The picture may not reflect the actual color of the item. Thank you! Package

$3.00 Shipping Condition: New Location: China DS3231 is a low-cost. Extremely accurate I2C real-time clock(RTC) with an integrated temperature-compensated crystal oscillator(TCXO) and crystal. The ... moredevice incorporates a battery input, disconnect the main power supply and maintains accurate timekeeping. Integrated oscillator improve long-term accuracy of the device and reduces the number of components of the production line. The DS3231 is available in commercial and industrial temperature ranges, using a 16-pin 300mil SO package. RTC maintains seconds. Minutes, hours, day, date, month, and year information. Less than 31 days of the month, the end date will be automatically adjusted, including corrections for leap year. The clock operates in either the 24 hours or band/ AM/ PM indication of the 12-hour format. Provides two configurable alarm clock and a calendar can be set to a square wave output. Address and data are transferred serially through an I2C bidirectional bus. A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures. Provide a reset output, and if necessary, automatically switch to the backup power supply. In addition, RST pin is monitored as generating μP reset manually. Save time and high precision addition. DS3231 also has some other features that extend the system host of additional features and a range of options. The device integrates a very precise digital temperature sensor, through the I2C* interface to access it(as the same time) This temperature sensor accuracy is ± 3 ° C. On-chip power supply control circuit can automatically detect and manage the main and standby power(i.e. low-voltage battery) to switch between the power supply. If the main power failure, the device can continue to provide accurate timing and temperature, performance is not affected. When the main power re-power or voltage value returns to within the allowable range, the on-chip reset function can be used to restart the system microprocessor.
