Sonoff Micro Dissasembly and Flashing (kind of)
Dissasembly
In order to dissasemble it I had to scratch case all over. It seems everything is much simpler - you need really thin screwdriver to be inserted exactly where red marks are. Than it will un-snap and you can use another scredriwer to un-snap other sides.
SPI connection
Board contains V
, G
, R
, T
Pin group on one side
and LOG
, R
, T
, RST
and button on the other.
I’ve connected my programmer to the device (3.3V), but default way of copying firmware does not work here - not an ESP-compatible.
@esp_tool -pCOM12 -b115200 -a0x0000 -s0x100000 -or esp82XX.bin
Consumption
Unit consumes around 0.06A according to my usb-doctor.
Usage
I’ve noticed that there is no click sound when it turns on/off (compared to the big
modules with relays like sonoff basic or pow).
Button location is not perfect when you are connecting it to a USB hub (like orico), but it does not interfere with the other ports.
