+## Flash and GPIO pins
+Remove the ESP8285 daughter card DLX-MKCK01 from the main board and flash Tasmota.
+pin1 RST -> N76E003 P0.5/PWM2
+pin2 TXD -> N76E003 P0.7/RXD
+pin3 RXD -> N76E003 P0.6/TXD
+pin4 GPIO13/MTCK -> LED
+pin5 3.3V
+pin6 GND
+
+## Communication between ESP8285 and N76E003
+It uses AT command to communicate between ESP8285 and N76E003
+Turn on the switch from ESP8266:
+Send from ESP8266
+AT+UPDATE="sequence":"1528335040032","switch":"on"
+Receive from MCU
+AT+RESULT="sequence":1528335040032"
+Send from ESP8266:
+AT+SEND=ok
+After 0.7s
+Receive from MCU
+AT+UPDATE="switch":"on","bright":44
+Send from ESP8266:
+AT+SEND=ok
+
+Turn off the switch from ESP8266:
+Send from ESP8266
+AT+UPDATE="sequence":"1528335118327","switch":"off"
+Receive from MCU
+AT+RESULT="sequence":1528335118327"
+Send from ESP8266:
+AT+SEND=ok
+After 0.7s
+Receive from MCU
+AT+UPDATE="switch":"on","bright":44
+Send from ESP8266:
+AT+SEND=ok
+
+Change brightness to 44 from ESP8266:
+Send from ESP8266:
+AT+UPDATE="sequence":"1528335181502","bright":"44"
+Receive from MCU
+AT+RESULT="sequence":1528335181502"
+Send from ESP8266:
+AT+SEND=ok
+After 0.7s
+Receive from MCU
+AT+UPDATE="switch":"on","bright":44
+Send from ESP8266:
+AT+SEND=ok
+
+Turn on the switch with faceplate button:
+Received from MCU when
+AT+UPDATE="switch":"on","bright":44
+Send from ESP8266:
+AT+SEND=ok
+
+Turn off the switch with faceplate button:
+Received from MCU when
+AT+UPDATE="switch":"off","bright":44
+Send from ESP8266:
+AT+SEND=ok
+
+Change the brightness to 52 with faceplate button:
+Received from MCU when
+AT+UPDATE="switch":"on","bright":52
+Send from ESP8266:
+AT+SEND=ok
+
+Holding the middle button on faceplate to reset the device:
+Received from MCU when
+AT+SETTING=enterESPTOUCH
+Send from ESP8266:
+AT+SETTING=enterESPTOUCH
+
+The sequence number is a 13 digits unix timestamp. The data after "bright" is the brightness. The maximum of the brightness is 100 and the minimum is 10.
+There is one byte 0x1B at the end of each AT command.
