Programmable timer lite is a miniature, USB programmable timer module. This module can handle more than 100 alarm configurations and trigger the output channel based on the programmed conditions. The timer module can program using SRIKit's Timer Controller software.
This module is designed around the STM8S001J3M microcontroller and DS3231 real-time clock. AMS1117-3.3 regulator in this module can handle a maximum of 9V DC input without installing an external heatsink.
The alarm terminal of this module is available as an open-collector output.
This module is specifically developed to handle long-duration alarm configurations which can span up to years.
