💬 Wall Switch Insertable Node

[vikasjee]

Great! Which is the one with the transformer? any link to it?

[yury]

We are changing PCBA contractor which is supposed to assemble Koresh projects. Since current one gave us way too many errors while assembling other projects for our "Day Job" we work with Koresh together. so may be some delay for all Koresh projects.

Hello
Will you build an nrf24l01 smd version ?

[blacey]

Interesting board. While you have designed this to be a wall-insertable board, one could envision packaging this into a small case with 4 buttons attached to the surface for a portable scene controller/remote. Well done!

[Cliff Karlsson]

Is it possible to buy this board assembled from you now?

[Koresh]

@Cliff-Karlsson
Hope the batch of assembled boards (latest version after all fixes) will be ready in a week.

[Sander Teunissen]

@koresh Great to hear you have assembled components available! I am following your other projects too (like the usb dongle and switchable power supply) .Will these become available as assembled components too ?

[Koresh]

Board works with nrf24 too :wink:

[Samuel235]

@Koresh - Do you happen to have a link for the JST connectors? I can't seem to find any at a reasonable price at the moment. And the male side too, if you don't mind me asking :)

The price depends on a batch size. You can try to ask any supplier on ali for 100-200 pcs and may be price will be reasonable :)

This looks great. I would be interested to purchase assembled units. Question: any idea what would the cost approximately? And CE certification is that something for the very long term or doable in the near future?

[markjgabb]

^ +1 absolutely....i would back this

[Koresh]

Unfortunately I can't open my ebay shop right now. While I'm trying to open it, you can buy this board here: https://www.ebid.net/eu/for-sale/arduino-ide-compatible-coincell-powered-switch-controller-rfm69cw-433-mhz-radio-156694971.htm

[Koresh]

I've prepared several kits for true soldering amateurs :wink:

[jeremushka]

Which kind of switches can we plug? normally losed or any kind of light switches already installed in the house?

[Koresh]

@jeremushka We can use any switches\buttons with this board. So you can use both ON/OFF and momentary switches.

[jeremushka]

@Koresh interesting. What about the battery life? how did you optimize your code in order to have at least battery life 1 year ?

[Koresh]

@jeremushka
There are no problems with battery drain in this circuit. The MCU sleeps between buttons action. Any changes of button state cause rising edge on the interrupt pin and intterruption routine calling (both of open and close events). We check buttons state only during interuption routine. If you use ON-OFF buttons each of buttons in closed state will increase current consumption by ~3uA. Which is not very critical ;)

[jeremushka]

@Koresh indeed 3uA is nothing. However, the light can always be on or off if the circuit has some problems. Because no action on light switch will be possible.

" if the circuit has some problems"

Could please elaborate more on your findings? Did you notice any bugs in the code or in schematics?
