I read the following thread and BCM20737S SiP Module technical reference, but I couldn't find how much current each GPIO pin can output.

Max I/O Current for BCM20736S

BCM20737S Bluetooth Low Energy SiP Module Technical Reference

Particularity, I want to know how much current P26, P27, P28 can output to control some full color LEDs with cathode common.

Furthermore, I would like to know how much current GPIOs of BCM20737S can output simultaneously, too.

Best Regards

Look up the gpio section of this doc:

WICED™ Smart Hardware Interfaces

"all gpios can source or sink up to 2mA. p26/27/28/29 can sink up to 16mA."
