Wi-Fi controlled PC ATX PSU

An interface PCB capable of turning on/standby a PC ATX style Power Supply. The board accepts an ESP12 type WiFi module (not included) and is used to control the PSU’s PS-On signal (pin 16).

LED’s are provided for each DC supply output plus an LED and push button for local control.

Ideal for powering LED lighting strips using cheap ready available power supplies and controlled by WiFi.

ESP Programmer New Version

A USB programmer for the ESP8266 or ESP32 chips from Espressif Systems. This board uses the CH340 USB to serial interface to program the ESP devices. The board also uses the GPIO0 and Reset lines to aid programming, just as Wemos and NodeMCU development modules.

Using an external programmer makes the target board easier and cheaper to build without the USB interface, this also aids with lower power modes used for battery operation. Not having to power the USB interface can save precious battery power.
