which product is best for me?

[salarbn]

Hi,

We are working on our new product which needs a BLE connection with a mobile phone.

Our requirements are as follow:

1) Four digital output. (It's preferred to be six pins with PWM.)

2) One digital input.

3) One PWM output with a frequency of about 35KH. (It's Optional)

4) An analog input.

5) At least 15 meters of physical range when there are not any obstacles.

Which product is the best optimal choice for us?

Is it possible to program the nRF52 using Arduino IDE?

Is there any document for designing the antenna?

Many thanks for your guidance.

Our first concern is about the range.

What is the maximum range of nRF52810 in the case of using a PCB antenna? How about nRF52832?

َAccording to the documents that I have read, I think achieving a 20 meters range is not difficult.

Is there any straightforward document on PCB antenna design?

You can get 500m range at +4dBm with either of the devices, most likely 100+ meters at 0dBm.

You can grab the antenna from the DK: https://www.nordicsemi.com/-/media/Software-and-other-downloads/Dev-Kits/nRF52-DK/nRF52-Development-Kit---Hardware-files-2_0_0.zip 

You should also read nWP008 - λ/4 printed monopole antenna for 2.45 GHz. 

In general you need to read Product development with nRF5 Series SoCs.
