4 Channel Programmable Relay Module

Numato Lab’s 4 Channel Programmable Relay Module is a feature-rich product that can be programmed with Arduino IDE. The USB to Serial Chip FT232RL helps to upload sketches quickly to the board. This programmability gives this board ultimate flexibility compared to other relay modules where features depend on the pre-programmed firmware. The onboard programmable relays, digital I/O’s, analog inputs, Real-Time Clock(RTC), and Micro SD memory card slot make this module useful for learning as well as making sophisticated applications.
