6.1 Test Points
The test points located on the left of the touch pads are routed to the capacitive sense input traces and power rails.
The capacitive sense input traces can be accessed through the vertically aligned vias located in middle of the board on the left of the
touch pads. All 13 CPT213B capacitive sensing touch pads are bound to each via.
At the bottom left corner of the board, there are two test points for VMCU labeled "ST1" to measure the active current of the board
using an in-circuit ammeter. A 2.54 mm pitch pin header can be soldered in for easy access to these pins.
Note:
In order for the capacitive sense pins to be connected properly to your application or power to be measured correctly, the 0 ohm
resistors must be removed. The 0 ohm resistor for a channel can be found next to the corresponding via on the top side of the board.
At the top left corner of the board, there are three test points for Config Clk, Config Data, and GND to allow programming of external
CPT devices.
