Universal Serial Bus Port Management Controller Solution USB Type-C PD 3.0 Fast Charging

This solution includes USB Type-C® PD 3.0 hardware layer driver and software protocol stack for developing USB PD applications. The M032 series acts as a universal serial bus port manager, and the NCT3807 is a port controller. Its software stack supports the USB-IF Association's power supply/charging specifications. This solution supports dual-port applications, and Nuvoton has extensive experience in USB Type-C® PD 3.0 product design.

ESP32Picoremote: ESP32 WiFi remote control with TFT display, mini TV, capable of playing GIFs

The WiFi remote control is based on ESP32 Pico D4 MCU and 160x80 pixel mini TFT display. Additionally, there are onboard I2C temperature and humidity sensors and an accelerometer.

Application of 3V DAC in ±10V

Many modern systems have the majority of their electronics powered by 3.3V or lower, but must drive external loads with ±10V, a range that is still very common in industrial applications. There are digital to analog converters (DACs) available that can drive loads with ±10V swings, but there are reasons to use a 3.3V DAC and amplify the output voltage up to ±10V.
