MIKROE PULSE Click is a pulse generator with an adjustable frequency. It carries the NE555 precision timer capable of producing highly accurate time delays. The frequency of PULSE Click is configured in two steps. First select between four frequency bands by using the frequency selector - a circular central switch in the middle of the board. Starting from the six-o-clock position and moving counter-clockwise in quarters, it has 4 options: 0) Up to 100 Hz; 1) Up to 1 kHz; 2) Up to 10 kHz; and...

MIKROE RTC2 Click is an accessory board in mikroBus™ form factor. It features the DS1307 serial real-time clock (RTC). It is a low-power, full binary-coded decimal (BCD) clock/calendar with...

MIKROE RTC2 Click is an accessory board in mikroBus™ form factor. It features the DS1307 serial real-time clock (RTC). It is a low-power, full binary-coded decimal (BCD) clock/calendar with programmable square-wave output signal. Board uses I2C interface for communication, and can only use 5V power supply. Board features a 3V/230mA lithium battery as a backup power supply which ensures that timekeeping operation continues even when the main power supply goes OFF. Features: Interface: GPIO,...

MIKROE Watchdog Click is a compact add-on board that contains a simple countdown timer for a wide variety of applications. This board features the TPS3430, a standalone watchdog timer with a programmable watchdog window and programmable reset delay from Texas Instruments. The TPS3430 has the watchdog output reset delay set by factory-programmed default delay settings or programmed by an external capacitor. It achieves 2.5% timing accuracy at the typical temperature of 25°C and can be disabled...

Here is a real time clock based on the DS3234 Real Time Clock IC. The DS3234 is a low-cost, extremely accurate SPI bus real-time clock with an integrated temperature-compensated crystal oscillator and crystal. The RTC maintains seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections of leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM...

This is the SparkFun Real Time Clock (RTC) Module, this little breakout that uses the DS1307 to keep track of the current year, month, day as well as the current time. The module comes fully assembled and includes a small CR1225 Lithium coin cell battery that will run the RTC for a minimum of 9 years (17 years typical) without an external 5V power supply. The DS1307 RTC is accessed via the I2C protocol. We've written a test-bed to program the modules, this code should give you some insight on...

Get with the times, already! This SparkFun Real Time Clock (RTC) Module is a Qwiic-enabled breakout board for the RV-1805 chipset. The RTC is ultra-low power (running at only about 22nA in its lowest power setting) so it can use a supercapacitor for backup power instead of a normal battery. This means you get plenty of charge and discharge cycles without any degradation to the “battery." To make it even easier to get your readings, all communication is enacted exclusively via I2C, utilizing...

The SparkFun RV-8803 Real Time Clock Module is a Qwiic-enabled breakout board for the RV-8803 RTC. The RV-8803 boasts some impressive features including a temperature compensated crystal providing extremely precise time-keeping, low power consumption, and time stamp event input along with a user-programmable timing offset value. The RV-8803 also has an improved I2C interface compared to the RV-1805 RTC that removes the need to sequence commands/writes to the device. Best of all, the...
