Tab le 4 and Table 5 detail the solder pad connection definitions and available functions for each connection pad. Table 4 lists the
solder pads on CYBLE-224116-01, the BLE device port-pin, and denotes whether the digital function shown is available for each
solder pad. Table 5 denotes whether the analog function shown is available for each solder pad. Each connection is configurable for
a single option shown with a

Notes
2. TCPWM stands for timer, counter, and PWM. If supported, the pad can be configured to any of these peripheral functions.
3. The main board needs to connect both GND connections (Pad 1 and Pad 32) on the module to the common ground of the system.
