ESPUSB – An USB Software Stack For ESP8266
ESP8266EX and even the new ESP32 SoC lack a USB hardware transceiver, so [CNLohr] decided to develop a USB software stack for ESP8266. After a quick search, I think it is the first try to do a USB software stack for esp8266. USB software stack is a firmware-only implementation of a USB....

LTC3623 is a ±5A high efficiency, current mode synchronous buck regulator that is adjustable from 14.5V down to 0V output with a single resistor. Its architecture uses a 50 µA current reference, combined with a single resistor, to set the output voltage. by Graham Prophet @...
