An electronic brick is an electronic module which can be assembled like Lego bricks simply by plugging in and pulling out. Compared to traditional universal boards and circuit modules assembled with various electronic components electronic brick has standardized interfaces plug and play simplifying construction of prototype circuit on ones own. There are many types of electronic bricks and we provide more than twenty types with different functions including buttons sensors Bluetooth modules etc whose functions cover from sensor to motor drive from Ethernet to wireless communication via Bluetooth and so on. We will continue to add more types to meet the various needs of different projects. Electronic brick of relay can be connected to digital I/O port when the input of S port is low level relay will be under disconnectstate; when the input of S port is high level relay will be under connectstate. It can be connected in series to the LED lights buzzer or even the loop of a small lamp so as to control the state of the switch. Features 1. Plug and play easy to use. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market. 2. With use of M4 standard fixed holes compatible with M4-standard kits such as Lego and Makeblock. 3. With protection circuit to prevent from burning the relay coil when disconnected; with isolation circuit to prevent damages to I / O port by relay switch current . 4. With LED status lamp to indicate whether it is currently connected or not. 5. Terminals with screws for easy wiring and removing.
