AIROC™ Bluetooth® LE module
GPIO port
11 GPIO port
GPIO ports for this device is shown in Table 4-2. The CYBLE-3x307x-02 uses 24 general-purpose I/Os (GPIOs). All
GPIOs support programmable pull-ups and are capable of driving up to 8 mA at 3.3 V or 4 mA at 1.8 V, except P26,
P27, P28, and P29, which are capable of driving up to 16 mA at 3.3 V or 8 mA at 1.8 V.
P28-P29, P32, P34, P38: all of these pins can be programmed as ADC inputs.
Port 26-Port 29: All four of these pins are capable of sinking up to 16 mA for LEDs. These pins also have the PWM
function, which can be used for LED dimming.
