It uses CH340G IC as a USB-to-UART adapter and MAX232 for converting 5V UART logic levels to RS-232. The device can also be used as USB-to-UART adapter if MAX232 IC is not assembled. If you like this ...
Many embedded devices' UARTs are broken out through a header with 5V (Arduino) or 3.3V (Beaglebone ... such as USB to DB9, DB9 to RJ45, USB to TTL (FTDI), and null modem/rollover adapters. The adapter ...
When connected to the 12W adapter, iOS refers to it as a 12W “USB brick” (12W = 2.4A x 5V). With that charger and the screen turned off, iOS reports an average gain of 1680 mA, which, considering that ...
