What is it?

This timer switch relay is based on on-board RTC and 8 channel of 2 A relays, for projects that need timer switching. With MaTouch 1.28”, the 8 channel relay can be either manually control or set to timer switch for auto controlling, support Max 5 groups of timer.

This Timer Switch is preloaded Makerfab’s firmware/UI, intends to easy usage for common end-users, as a ready-to-use timer switch. Besides, as all the hardware/firmware resource open, this module also a good platform for engineers remaking, such as remoting controlling via IFFFF/ home assistant, with the core controller ESP32S3 Wifi functions.

MaTouch 1.28” ToolSets are series of ESP32-based products mainly consist of MaTouch 1.28” controller and kinds of functional expansion such as Dimmer/ Relay Controller/ Motor Driver, etc. It’s designed as tools to control/drive these actuators directly while also keep open hardware/software, which make it possible for users’ remaking and integration to other field projects.
