A simple breakout board for pulling both 5 and 12 volts from an ATX power supply. Also includes a spot for an LM2596 module connected to the 12 volt rail for an adjustable output.

A basic board meant to be used with the BlueRetro project to simplify basic “HW1” internal installation in various supported consoles. Including onboard level shifting via a pair of TXS0108E buffer chips and a 3.3V regulator for consoles which don’t provide it.

The final, compact version of the MooLED NeoPixel controller powered by WLED.

The 74AHCT125 4-channel signal buffer has been replaced by a pair of single channel variants, and the GPIO pins used for data and relay signalling have been reverted to the defaults used by WLED for the ESP32 (GPIO 16 and 12 respectively).

BOM: - ESP32 “D1 Mini” style development board, - 2 x TI SN74AHCT1G125 buffer (SOT-23-5), - 0603 470Ω resistor, - 10.5mm 1000uF electrolytic capacitor (10v or higher, whatever will fit), - G5LE style SPDT relay (5v coil voltage required!), - 3 pin MSTB style 5.08mm pluggable terminal connector, - 2 pin MSTB style 5.08mm pluggable terminal connector.

NOTE: There is no on-board fuse on this PCB. For larger current lighting projects using this board an in-line fuse between this controller and the power wire going to the LEDs will be necessary.

A revised version of my DC Distribution PCBs, instead of separate designs for polarity it has a pair of jumpers on the underside of the board.

Still uses the same switching 2.1 or 2.5mm barrel jack and Phoenix MSTB 5.08mm type connectors as before.

A basic three-channel NeoPixel controller meant to be used with the WLED project. With 74AHCT125 level shifter, relay for LED power and support for either ESP8266 or ESP32 “D1 Mini” type devboards.
