Module with relays controlled by the I2C interface. The board allows you to place up to four relays. Due to the fact that the module is based on the ATTiny84 microcontroller, they can be controlled via the I2C interface. ATTiny84 is pre-programmed. The I2C ATTiny84 address is software configurable. Each relay can switch currents up to 40 A at 28-380 V AC.
The kit does not require soldering. In order to connect the relays to the board and AC load, it is necessary to screw the relays and connect the wires.
Arduino libraries are available for the module.
Attention!
The black standoffs and 4-40 screws used to secure them shown in some of the photos are not included with the kit.Responsible person BTC Korporacja sp. z o. o. Lwowska 5 05-120 Legionowo Poland sprzedaz@kamami.pl 22 767 36 20

Module with monostable relay. It allows you to control high-power elements with a microcontroller. Adafruit 3191
Module with a 12 V relay and a timer. It allows you to turn the device on and off cyclically at a specified time using potentiometers. It can also operate in single trigger mode, which allows the device to be turned on after a signal has been applied for a specified period of time. The operating time can be adjusted from 1 s to 100 s or from 1 s to 15 min
