Hardware
5.1.6 CapSense Circuit
5.1.6.1 CapSense Slider
The BLE Pioneer Kit has a five-segment linear capacitive touch slider, which is connected to the
PSoC 4 BLE/PRoC BLE Module pins (see Figure 5-13). The CMOD and CTANK capacitors are
required for CapSense functionality and are provided on the modules (see Module Board on
page 107). A 2.2-nF capacitor is present on the CMOD pin, P4[0], for CapSense operation. BLE
Pioneer Kit also supports CapSense designs that enable waterproofing. The connection of the shield
to the pin or to ground is made by resistors R12 and R13, respectively. By default, R13 is mounted
on the BLE Pioneer Baseboard, which connects the shield to ground. Populate R12 and remove R13
when evaluating waterproofing designs, which will connect the shield to the designated pin, P1[6].
