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. 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.
Save time and high precision addition, DS also has some other features that extend the system host of additional features and a range of options. On-chip power supply control circuit can automatically detect and manage the main and standby power i. 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. Shipping list:. DS module a tested good antistatic packaging.
Note: don't inclue battery,it only need 0. Mini DS module with battery. DS high precision clock module for Raspberry Pi 2. The module itself can be adapted to 3. Features: 1. To provide continuous timing battery backup 3.
Low power consumption 4. Sure thing! Description: Another great linear actuator from Miga Motors. Previous poster beat me to it - yes Darlington array can handle the mA and will help drop 5V down to the 3.
Just be careful about total power dissipation if powering 4 of these devices Darlingtons saturate at a volt or more. No but you can minimise it by having a component that does not drop as much voltage when it is on.
A good logic level FET will not dissipate as much power. You could use relays. I just ordered some from futurlec.
