NRF51 obsolete

[ofer]

I heard that NRF51 familey is becoming obsolete and the NRF52 replaces tham is it true because we have a product the uses NRF511822 and we want to make another product using the same processor.

Thanks

This is not the right forum to ask. As you will hear from Nordic support any such question should be sent in private to your account/regional sales manager.

However it's publicly known that Nordic strongly recommends all new designs on nRF52 only because logically nRF51 will be phased out at some point... (BLE stack is not developed further, the same with nRF5 SDK support)
