Configuring and Connecting Hardware

Verify that the RSL15 EVB has the default jumper configuration, which is VBAT and VOUT pins jumpered on the VBAT-SEL header, and VBAT and VDDO pins jumpered on the VDDO-EN header. See the "EVB with Default Jumper Configuration" figure. The red boxes indicate default jumper positions.

IMPORTANT: Ensure that all of the DIP switches on the VDDO-EN header and the DEBUG-EN switches are in the default ON position, as shown in the "EVB with Default Jumper Configuration" figure.

Once the jumpers are in the correct positions, you can plug the USB cable into the EVB. When powered, the blue LED flashes rapidly (it flashes slower when connected to the RSL Central mobile app). See the RSL15 Evaluation and Development Board User's Guide for more power options available for the RSL15 EVB.
