8. Recommended configuration
This chapter describes a recommended configuration which enables use of all frequently
used interfaces. The schematic symbol used in this chapter as well as a footprint can be
found in dresden elektronik Altium and Eagle libraries (see Section 7.3). Figure 10-1 shows
the schematic of a sample application. The sample application provides USB and
incorporates two sensors, a LED, an analogue input measuring the battery voltage and using
the UART interface through a 6-pin header for tracing. This configuration with all common
interfaces is shown in Figure 10-1.
