Why does pixel binning remove colors and provide monochrome image only with CMOS color cameras?

It could be because of the Bayer (color filter) array, although that depends on the camera manufacturer making a particular set of decisions. Adjacent pixels have filters in front of them that make ...

How can a charger charge both a phone and a laptop?

The "charger" only provides power at constant voltage and the actual charging logic is within the device being charged. USB-C specification allows the slave device to select the voltage ...

USB transfer speed vs charging power

The e-marker chip is just that: a marker. It can mark many different things, and 5A current carrying capability is just one of the things it can mark. It doesn't have to. For example, I've been ...

How to get more current from laptop usb 3 port

USB 3.0 standard says it can provide up to 4.5W (0.9A@5V) of current, with dedicated downstream charging USB 3.0 ports providing maximum 1500mA (7.5W). 5V/2A is simply not possible. The internal ...

Shorting the USBLC6 ESD protection pins

Yes, that strategy will negatively affect ESD protection. The equivalent pspice model shows this: There is an impedance on both sides of the data lines (likely caused by the package leads and bonding ...

Why does pixel binning remove colors and provide monochrome image only with CMOS color cameras?

There is no hardware reason this is done, and not all CMOS cameras revert to monochrome when binning. Most likely the vendor did not expect demand for the feature and so did not implement it. ...

Do I need a diode in my circuit when using a USB-powered DC power supply to power a laptop camera?

2 silicon diodes in series will have a nominal voltage drop of 1.4V. 5V source from the USB - 1.4V drop from the diodes = 3.6V. Most 3.3V devices are probably maybe fine with 3.6V. This isn't ideal as ...

TUSB2036 hub IC: only mouse and keyboard work at downstream ports

The datasheet qualifies the TUSB2036 as "full speed" hub, which is USB 1.1 (1.2 MBit/s) There is no bug in your circuit and no software will make a high speed hub out of it. It is just doing ...

Routing USB signal on RP2040

For USB FS stubs of an inch length – what you seem to be showing – it doesn’t matter much what you do in terms of impedance. Just route the traces close together over a ground plane and all is good.

Routing USB signal on RP2040

USB connectors are compatible. If you use USB 3.0 but use only USB 2.0 pins, it is equivalent to plugging a USB 3 device to USB 2 socket, or plugging USB 2 device to USB 3 socket. "Best" ...
