I am using BL4S200. I notice BL4S200 support sinking output and pull up to 5VDC, is it possible to make digital output pull down to 0VDC because this will make board start as logic “0”.
The high-current digital outputs on the BL4S200 are able to sink or source up to 2A. See section 3.2.2 of the user manual.
That means 5VDC digital output can’t pull down to 0VDC? The high current digital output have been signed for other purpose.
