About the RPi-HAT-RGBW-LED-Controller

RPi-HAT-RGBW-LED-Controller is an open source PCB design by mikelawrence, published on GitHub under the MIT license. It is a 2-layer board measuring 65 × 56 mm, with 54 components from 24 distinct parts.

Other key parts include the AT24CS32-SSHM, PCA9685PW, OKI-78SR-5/1.5-W36H-C, LM3414MRX/NOPB and DS18B20U+. By type, the board carries 14 capacitors, 14 resistors, 8 ICs, 6 connectors, 5 diodes and 4 inductors.

It belongs with the dev boards & breakouts and iot & wireless designs in this gallery.

From the project

This is a Raspberry Pi B+ HAT that supports four high power LEDs. Main application is an RGB Floodlight.

This PCB is designed using KiCad 5.0.0. This HAT is based on RPiHatTemplate by XESS Corp.

Note: The LM3414 parts have an exposed pad on the bottom which requires either a reflow oven or hot air to solder properly.

Note: This HAT does not have the camera flex slot or the display flex cutout so technically cannot be called a HAT.

The Raspberry Pi can be safely back-powered by this HAT because the Ideal Diode circuit provides protection to both the Raspberry Pi and this HAT when the Raspberry Pi is powered by another source. Maximum Raspberry Pi power is 1.5A. Usually the Raspberry Pi will…
