Würth Elektronik has introduced the Ophelia-III radio module as part of its innovative “Build Your Own Firmware” concept. This module allows developers to create custom radio solutions within the 2402 to 2480 MHz frequency range. Unlike typical modules, Ophelia-III comes without pre-installed firmware and is accompanied by a software development kit (SDK), offering flexibility for a wide range of applications, from Bluetooth LE to proprietary, highly customized radio protocols.
Powerful Hardware and Compact Design
Ophelia-III is powered by the nRF52840 chipset from Nordic Semiconductor, featuring a 32-bit ARM Cortex M4F CPU. It is equipped with 1 MB of flash memory, 256 kB of RAM, and multiple interfaces such as UART, SPI, I²C, ADC, 17 GPIOs, and Nano-SIM. Measuring just 12 × 8 × 2 mm, this compact module is smaller than many comparable options on the market. Its optimized antenna design ensures low power consumption with a transmission power of up to +8 dBm. In sleep mode, the module draws just 0.4 µA, making it an ideal choice for battery-powered devices.
Flexibility in Application Development
The Ophelia-III module is designed to offer developers maximum flexibility. It includes both an internal antenna and an antenna connector, along with 17 configurable GPIOs, enabling a wide range of customization options. Developers can create tailored solutions using the same hardware platform as the popular Proteus-III Bluetooth LE module, and certification documents from Proteus-III can be reused for Ophelia-III solutions, simplifying the certification process.
For those interested in developing applications, Würth Elektronik provides an evaluation board and a software development kit (SDK) to help streamline the development process.
