Compact PCB to control up to 8 loads via relay with dry-contacts (both NO and NC available). It has 230VAC-5VDC power supply onboard (optional) and 3.3V voltage regulator. Relays are controlled via port expander (MCP23017) that uses I2C protocol. PCB Dimensions are 100x100x20mm. An FTDI programmer is required for first time firmware loading (then you can use OTA if enabled). ADC input is 0-3.3V tolerant with on-board voltage divider. Please note that your firmware must support MCP23017 in order to operate the relay and access the extra 8 GPIO pins available. LEDs on board for testing purpouses (you can disabled them before final installation with a simpler jumper pin)
