What do you need to create a bluetooth bracelet?

Question

Bluetooth

What consumables are needed? I looked at bracelets with an open api, but I was confused by the price, is it possible to create a bracelet by spending 500-1000 rubles?

Answer 1

1000 rubles - at best, this may be enough for some of the details for the bracelet. the cost of materials and electronic components in the wholesale price. And that probably won't be enough.
Almost always a bracelet is the use of non-standard solutions.
Look, for example, at the bracelet from MS.
For 1000 rubles, if you do not take into account the time spent on its creation, you can do something in the form of a screen from an LCD, MK mobile phone, a battery with a bluetooth and a couple of buttons for interaction.
You will have an almost smart bracelet for 1000 rubles and work with android.
