 Overview
 ********
 
-The nrf52dk_nrf52810 board is a modified version of the :ref:`nrf52dk_nrf52832`
-that enforces the limitations imposed by the nRF52810 IC, which is a
-cost-reduced variant of the original nRF52832. Since Nordic does not offer a
-development kit for the nRF52810 you can use this board to develop for this
-IC while using the nRF52 Development Kit (PCA10040).
+The Holyiot 21014 hardware based on the Nordic Semiconductor nRF52810 Arm Cortex-M4 CPU.
 
-See :ref:`nrf52dk_nrf52832` for more information about the development board and
-`nRF52810 website`_ for the official reference on the IC itself.
