1 Introduction
1.1 Operational description
The Ophelia-I is a radio module for wireless communication between devices such as control
systems, remote controls, sensors etc. The module is based on the radio chipset nRF52805
from Nordic Semiconductor and is meant as hardware-only module: no firmware is imple-
mented on the module. It is customer’s responsibility to develop the firmware for the module
fulfilling the requirements of the specific application.
Since the Ophelia-I does not integrate any firmware, no radio certification is provided for
this radio module. Nevertheless, the Ophelia-I is ready for CE/RED, FCC, IC and TELEC.
The Ophelia-I hardware platform mounting Bluetooth
®
LE firmware has been tested within
the certification of Proteus-e [3]. Test reports can be requested from BDM or support.
Depending on the firmware developed and flashed on the module, a wide range of applica-
tions is possible. For example, the module can be configured to communicate with external
sensors, can use security configurations, and can be optimized for low power consumption.
Ultra small dimensions of 7 x 9 mm including a strongly miniaturized PCB antenna make
the Ophelia-I ideal for small form factor design. It is possible to connect an external antenna,
in case higher radio ranges are required.
For firmware development and all functional topics, please refer to the documentation and
resources available for the nRF52805 chipset [1].
For firmware customization topics, please refer to chapter
and to the Bluetooth
®
5.1 ra-
dio module Proteus-e [3].
