The image shows a blue-colored relay module with the word "BESTEP" written on it. The module is rectangular in shape and has a black circuit board attached to it. On the left side of the module, there are two blue capacitors, one on top and one on the right side. The capacitors are labeled "1 Relay Module" and appear to be used to control the relay. There is also a red and green switch on the circuit board, which is likely used to connect the relay to a power supply.
