Evaluation board extends life expectancy of SensiBLE module

A breakout board has been released by Recom, designed to connect SensiEDGE’s SensiBLE v1.0 sensor module to Recom’s R-78S evaluation board. The board enables the SensiBLE to draw a stable 3.3V from an AA battery down to voltages as low as 0.65V. Engineers can therefore replace the coin-cell battery with a higher-capacity single-cell AA battery and significantly increase operation lifetime on a single battery.

Recom’s breakout board SBL-1 for the R-78S evaluation board enables engineers to consider an alternate power source for the SensiBLE sensor module whose input voltage from a coin cell quickly drops below 2V after only a few hours of use. Recom points out that the transmission unit may be prevented from operating properly and leaves the energy from the coin cell battery wasted. This can be avoided by combining the R-78S which boosts a single-cell AA battery voltage of 1.5V up to a stable 3.3V, demonstrated by the R-78S evaluation board.

Test points for measuring voltages and currents make it possible to effortlessly calculate the typical battery lifetime for the SensiBLE in both active and standby modes, claims Recom. The engineer can now replace the SensiBLE’s coin-cell battery with a higher-capacity single-cell AA battery. Eliminating the coin cell guarantees a much longer application lifetime while reducing maintenance costs. There is also an option to use external input voltage from other low voltage sources such as energy harvesting devices which are typical in remote applications.

The R-78S evaluation board and the corresponding breakout board are available at authorised Recom distributors.

Recom Power supplies a range of DC/DC and AC/DC converters in every power class up to 480W alongside switching regulators and LED drivers in a wide selection of designs. Innovations such as the company’s R-78 switching regulators have become industry standard.

The headquarters in Gmunden, Austria, includes a logistics centre and laboratory wing. Recom has a worldwide distribution network to deliver the company’s products to customers worldwide.
