Display, OLED, 0.96-inch, BlueOLED Display 0.96 Inch OLED Display 128X64 Module for ArduinoThese displays are small, only about 1\" diagonal, but very readable due to the high contrast of an OLED display. Since the display makes its own light, no backlight is needed. This reduces the power required to run the OLED and is why the display has such high contrast.This breakout can be used with either an SPI or I2C interface - selectable by soldering two jumpers on the back. The design is completely 5V-ready, with an onboard regulator and built in boost converter. It\'s easier than ever to connect directly to your 3V or 5V microcontroller without needing any kind of level shifter!No embedded fonts inside the OLED controller, user can create the fonts through the font generation software.Features:High resolution: 128 * 64Viewing angle:> 160 degreeSupports many control chips: Fully compatible with UNO, Mega, 51 Series, MSP430 Series,STM32 / 2, CSR IC, etc.Ultra-low power consumption: full screen lit 0.08WDisplay area: 29.42 x 14.7mmVoltage: 3V ~ 5V DCWorking Temperature: -30 c ~ 70 cModule Size: 27.0MM * 27.0MM * 4.1MMI2C/IIC Interface, need 2 IO only.Driver IC: SSD1306Character Color: Blue Pin definitions:1> GND (power ground)2> VCC (positive power supply)3> SCL (clock line)4> SDA (data line) 3.

Real Time Clock RTC Module, DS3231DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.The device incorporates a battery input, disconnect the main power supply, and maintains accurate timekeeping. Integrated oscillator improves 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 offerirectional 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 uP 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).The temperature sensor accuracy is +- 3 degrees 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.
