Würth Elektronik has introduced two highly compact radio modules that give developers maximum freedom in designing proprietary wireless solutions that go beyond standard protocols. The hardware of the Tarvos-e and Olis-e modules, measuring just 12 x 8 x 2 mm, is identical to that of the Metis-e radio module and is based on the Texas Instruments SoC CC1310 chipset, operating in the 868 MHz frequency band.
Metis-e was introduced at the end of 2024 as a solution specifically for radio transmission of meter readings (wireless M-Bus). Their compact design, together with their energy-efficient operating modes, make the radio modules ideal for use in battery-powered devices - in the standby and shutdown power-saving modes, they require only 1,6 µA and 200 nA, respectively.
The Tarvos-e module uses Würth Elektronik’s proprietary WE-ProWare radio protocol and is compatible with Tarvos-III and Thebe-II. It allows targeted optimisation of wireless communication, either for high data rates up to 400 kbps or for a range up to 2,7 km. It offers maximum flexibility and is ideal for applications where standard protocols have reached their limits. The module delivers an RF output power of 14 dBm and uses a UART interface for communication.
The Olis-e module offers even more design flexibility by allowing designers to build their own firmware. Using the TI SIMPLELINK CC13x0 software development kit, developers can implement their application directly on the SoC – including custom wireless protocols and system logic.
The radio modules use proprietary protocols and thus offer an especially attractive solution for applications in which both the transmitter and receiver sides are individually developed. Compared to Bluetooth, the module has greater range thanks to its use of the 868 MHz frequency band instead of 2,4 GHz. This enables more reliable communication, even through walls and other building structure obstacles.
The radio module is also available in a specially adapted variant for the 915 MHz frequency range for use in markets where the 915 MHz band can be used license-free.
