EPS8266 Relay 4x LC Technology

Hello everybody,

I'l quite new to the Arduino platform (I startet with the MBED platform). I bought recently a EPS8266 Relay 4x LC Technology module. It's contains a ESP-01 wifi module and a relay board with a N76E0003AT20 MCU.

I managed already to load my firmware to de ESP-01 module but i also want to change the firmware of the N76E003AT20 MCU. Has anybody done that already and can help met with it. The point is i only need 3 relays and want to change the fourth relay to an input.

I hope somebody can help me with that or point me in the right direction.

On the board are 7 pins and I think these you can use to program the N76E003AT20 MCU

Have a nice day

LOL.

It looks vaguely like those I have seen on eBay.

From what I can tell, you control it with an App. Not sure which App.
