6.2 Expansion Header
On the left hand side of the board is a female expansion header to connect to a Silicon Labs EFM8 or EFM32 Starter Kit (STK). The
connecter contains a number of output and communication pins that can be used to communicate with the MCU on the STK. The re-
sults from the touch qualification engine are routed out to these pins. Additionally, the VMCU, 3V3, and 5V power rails are also impor-
ted. The figure below shows the pin assignment of the expansion header.
The CPT007B SLEXP8007A outputs using GPIO.
The pin assignment of the expansion header and the peripheral function are listed below in the figure and table.
