GUIDE BY LORIS
As explained in various pages of inDomus (for example in the guides dedicated to Basic and TH-16 / 10-TH), the ITEAD family devices Sonoff Smart Home can be reprogrammed with firmware Sonoff-Tasmota or other Open Source firmware solutions.
To do this it is necessary connect physically to four specific contacts placed inside the devices through a device USB / TTL, but this operation requires, for the most part, welding on the device.
To avoid this boring (and for some difficult) operation there are several alternatives; our user Loris proposes a prointeresting jet, absolutely self-made, which shines with originality and effectiveness. In essence, with the help of a couple of clothes pegs and little else we will make a terminal block for contacts that can allow a solid physical connection to the devices such as to allow us the reprogrammage (regardless of the firmware that will be used) of the same.
In case you have an 3D printer, we suggest this proalternative jet.
The materials needed for this realization are:
- two plastic clothes pegs
- a pliers for electricians
- a screwdriver
- two screws
- four dupont cables
- a series from 4 PIN
- a welder
- a pair of scissors
- self-tightening clamps (small)
Let's see them in photos:
In the first instance we take the four contacts and make it hooks using pliers. If you want to get a "cleaner" job, buy and use a "spring" PIN in order to get a perfect adhesion to the PCB and avoid false contacts.
Now let's take the clothes pegs, and fix them with screws as from the following image:
Now, with the help of a heat source, fold one of the arms of one of the two pegs as shown in the photo:
Fix the Dupont cable as shown in the image using cable ties:
Now is the time for applize the product to our devices, which will not be offended by the simple effectiveness of the same:
|ATTENZIONE: remember that there is on our FORUM community an ad hoc section dedicated to Sonoff (and more generally to devices ESP8266), for any doubt, question, information on the specific merit of these components.|
