these were purchased (mix of 1-3 ch) 06/2019 and come with Sonoff v3.3.0 stock firmware. i believe OTA (sonOTA) doesnt work on this ver so serial flash it is.

June 2019 - Devices delivered with Sonoff v3.3.0 stock firmware.

board label: T0US TOUCH v1.0 2008.11.15
|
||||
Serial flashing works for this device. You may wish to check whether the [Sonoff DIY](Sonoff-DIY) flashing method works if this device is upgraded to v3.3.1.

Board label: `T0US TOUCH v1.0 2008.11.15`

* TX T0 US, 1-3CH boards are physically the same.
|
||||
* Only need the "top board" to flash (not the bottom relay part) -- don't power with mains (you can't if you only use top anyway)
|
||||
* R19 is tied to GPIO 0 to enter flash mode, just like on T1 but in a different spot for t0 (or US?).
|
||||
- Find the C2 (j1) pins and look directly up about half inch for r19
|
||||
* Ensure that you select 3.3v and **not 5v!** to flash the board.
|
||||
* ESP8285 - 1M - DOUT - erase flash - 115200 baud

Like the T1, this does not have enough room to solder a header on.

|

Use a piece of thick cardboard to lay your top board on. Firmly press some jumpers through the serial holes into the cardboard.
|
||||
|
||||
* my usb adaptor has 3v3 pin make sure to use this not 5v! your usb adaptor will power the board for flash.
|
||||
If you push these through at an angle will be good enough to make contact to connect to your serial adaptor, trial and error but is not hard. See photo below.

Regular flashing steps apply: connect Ground, Vcc TX, RX to your serial adaptor. Pay attention to TX/RX!

|

For flash mode, use another jumper through the ground hole on the C2 pins (left of the serial and label J1). Same as above, push the jumper through cardboard to secure it.

While powered off hold the other end of jumper to R19 and then power up (plug in your USB serial adaptor).

hold it for about 3 seconds after it powers up and remove it.
|
||||
you should not see the network status led flash anymore, then you know you're in flash mode. If its flashing power off and try again.
|
||||
Hold it for 3-5 seconds after it powers up before removing it.
|

|

Using the TX T1 1-3 template is fine although i have created a T0 template to look nicer. will update that asap.

|

|

Using the TX T1 1-3 device template will work. A new T0 template is forthcoming.
