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.
-
Could cyou please share BOM?
-
@MiKa oh.. pdf doesn't have some component names, sorry. I will try to share bom today. And of course I will update schematic after I test the board if needed.

@NeverDie why are you asking? Does this lens seem better than the one you are currently working with?
-
@Terrence
Just scoping out alternatives in case it's ever needed.
-
I am not sure this board is useful, but it works properly
-
This board fits the box good
-
may I ask how did you solder all the small SMD parts?
-
-
And which battery? Small 250 mAh Li-ion?

MultiRF MultiVoltage ProtoBox: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.

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.

May be. With usb and onboard charger of course

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).

MultiRF MultiVoltage ProtoBox: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.
I verified it in modeling software and in real life.

Do you have a photo of this?
-
@NeverDie I will make a photo on Monday.
-
@NeverDie Sorry for delay... This is example (improved version with 3d printed fixer)
