W\u00fcrth Elektronik presents its Tarvos\u2011e and Olis\u2011e radio modules<\/em> <\/strong><\/p>\r\n

Minimal Size, Maximum Flexibility <\/strong><\/p>\r\n

Waldenburg (Germany), September 30, 2025 \u2013 W\u00fcrth Elektronik introduces two new highly compact radio modules. They give developers maximum freedom in designing proprietary wireless solutions that go beyond standard protocols. The hardware of the Tarvos\u2011e<\/a> and Olis-e<\/a> modules, measuring just 12 \u00d7 8 \u00d7 2 mm, is identical to that of the Metis\u2011e<\/a> 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). Not only their compact design but also the energy-efficient operating modes make the radio modules ideal for use in battery-powered devices. In the Standby and Shutdown power-saving modes, the modules require only 1.6 \u00b5A and 200 nA, respectively.<\/p>\r\n

The Tarvos-e module uses W\u00fcrth Elektronik's proprietary WE-ProWare radio protocol and is compatible with Tarvos-III and Thebe-II. It allows targeted optimization of wireless communication \u2013 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 for which standard protocols reach their limits. The module delivers an RF output power of 14 dBm and uses a UART interface for communication.<\/p>\r\n

The Olis-e module offers even more design flexibility by allowing you to build your own firmware. Using the TI SIMPLELINK CC13x0 software development kit, developers can implement their application directly on the SoC (System on Chip) \u2013 including custom wireless protocols and system logic.<\/p>\r\n

Proprietary radio protocols as a potent alternative to Bluetooth\u00ae LE<\/p>\r\n

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 impresses with its greater range \u2013 especially indoors \u2013 thanks to use of its 868 MHz frequency band instead of 2.4 GHz. This enables more reliable communication, even through walls and other building structure obstacles.<\/p>\r\n

In addition to the standard version in the 868 MHz range, the radio module is also available in a specially adapted variant for the 915 MHz frequency range upon customer request. This option opens up use in markets such as the USA, in which the 915 MHz band can be used license-free.<\/p>\r\n

All three versions (Metis-e, Tarvos-e, Olis-e) include evaluation boards with a USB interface for connecting to a PC, a comprehensive user manual, as well as software tools.<\/p>\t\t<\/div>\n\t<\/div>\n<\/div>\r\n\t
