imple Circuit Modules. These modules may be used to construct simple circuits of the type normally implemented on, for example, a Worcester Circuit Board.
16×2 LCD + I2C
2 Channel Relay Module
This is a LOW Level 5V 2-channel relay interface board, and each channel needs a 15-20mA driver current. It can be used to control various appliances and equipment with large current. It is equiped with high-current relays that work under AC250V 10A or DC30V 10A. It has a standard interface that can be controlled directly by microcontroller.
