Would you please provide a link to the PIR lens that you're using?

@NeverDie No problem :)

Where do you buy them from? -

@NeverDie I bought this lens in the radio shop next street :) It is very difficult to buy something in my country so I hope it will be not so hard to find such lens in China.

OK, thanks for the answer. If anyone reading this finds it, please post where you found it.

@NeverDie why are you asking? Does this lens seem better than the one you are currently working with?
-
I am not sure this board is useful, but it works properly :wink:
-
This board fits the box good :wink:

Nice work! It looks like a commercial product.
Thanks a lot for your high appraisal of this device. I designed this board just for fun but now I really like it with this enclosure. I would plan to improove this board a little (omit unnecessary functions and add useful features) and to start production of this device.
@NeverDie said in 💬 MultiRF MultiVoltage ProtoBox:
What about the antenna?
I use very simple solution for all my boards. I just solder wire and fix it with glue pen to the board to improve reliability. Not very ideal for 433MHz board (~20cm) but perfect for 868MHz (~10cm). By the way I tested different modules with Yury (433/866). we found 868Mhz optimal frequency. Excellent range (up to 10x compareble to NRF) and very good feedthrough. So may be it is the most optimal rf solution.
@MiKa said in 💬 MultiRF MultiVoltage ProtoBox:
And which battery? Small 250 mAh Li-ion?
May be. With usb and onboard charger of course :wink:
@gohan said in 💬 MultiRF MultiVoltage ProtoBox:
may I ask how did you solder all the small SMD parts?
I soldered all of my prototypes by hand. I use simple soldering gun and flux. All boards batches are assembled on the factory of course (manually or automatic, depends on the batch size).

Maybe this could fit
https://www.aliexpress.com/item/10Pcs-433MHz-Helical-Antenna-2-5dBi-32mm-for-Remote-Contorl/32608690665.htmlI really do not recommend to use springs like this. It is not antenna it is... mechanical spring. I tried to use many of them and all of them are much worse compareble with single wire antenna. It has very bad characteristic. :-1: I verified it in modeling software and in real life.

Do you have a photo of this?
