They don’t appear on the GPIO connector so cannot be used on the Zero. The multi-pin, multi-purpose capability of the Broadcom processor allows you to switch PWM0_OUT to GPIO 18 and PWM1_OUT to ...

One possible way to do so is suggested by [Doctor Volt] in a video where a Samsung Galaxy S4 is combined with a USB-connected FT232R board to add external GPIO. The idea is pretty simple ...

This 28nm GPIO is designed for high-speed (>150MHz output, >250MHz input) applications. The IO operates at either 1.8V or 3.3V and can dynamically switch between these voltages during operation. The ...

SAMSUNG 11nm Flip-Chip IO library with dynamically switchable 1.8V/3.3V GPIO with fail-safe capability, 5V I2C / SMBUS open-drain cell, 5V OTP cell, 1.8V & 3.3V analog cells, and associated ESD. A key ...
