USB to Serial
This device contains an
ESP8266-LM1 chip inside.
In order to flash you need to solder on temporarily some wires to the following pins :
GND- top right pin
3v3- top left pin
UTXD- bottom, 2nd pin from the right - will connect to TXD on the FTDI board
URXD- bottom, 3rd pin from the left - will connect to RXD on the FTDI board
IO0- left side 3rd pin from the top - used to reset the device
Note, there is a
Reset button on the device but it cannot be used to enter flashing mode, you’ll need to connect the 5th cable
GND when connecting the FTDI cable.
Note there is no led on the board so you won’t see the status, you might be able to use a led strip, in my case it was quite flacky to show the status (sometimes the red color turned on when it was in flashing mode, otherwise none of the colors turned on but the flashing worked correctly)
Note: didn’t try with Tuya-Convert, might work with that too.
GPIO2- Reset button, if you configure it as
Button1then you can use it to turn On/Off the light strip
GPIO4- Warm white connector
GPIO5- Green connector
GPIO12- Blue connector
GPIO14- Cool white connector
GPIO15- Red connector After flashing you can use one of the following templates, depending on what kind of led strip you use.
Up to 5 individual light strips
You will also need to run the following command in order to get individual sliders for each led strip
Of course, you can play with the templates and configure it the way you want.
