truzzi 3-channel, high power RGB LED driver V1.0
2 layer board of 1.04x1.4 inches (27x36mm). $7.30 for three.
C1, C2, C3: 22uF tantalum capacitors (DigiKey part number: 399-3781-1-ND)
D1, D2, D3; Schottky diode 2A SMA package (DigiKey part number: B240A-FDICT-ND)
L1, L2, L3: 68uH power inductor, 0.7A (DigiKey part number: PCD2117CT-ND)
R1, R2, R3: 0.33ohm resistors, 0805 package.
4x screw terminals, 3.5mm (bought mine on Tayda Electronics)
3x PT4115 drivers.
1x 4-pin + 1x 2-pin male or female headers.

truzzi ATX PSU Breakout Mini V1.0
All SMD parts are 0805 or bigger
C1, C3: 0.1uF 0805 SMD capacitors.
C2: 1uF 0805 SMD capacitor.
F1, F2, F3, F4, F5: 1812 SMD PTC resettable fuses. (Littelfuse ones should work just fine, I used Bourns instead which are a bit larger).
J1: 24-pin ATX connector. I bought mine from Sparkfun but RS also sells them.
JP1: 3-pin header (for voltmeter output)
JP2: 6-pin header (for breadboard output, fused)
LED1, LED2, LED3, LED4, LED5, LED6: 0805 SMDs, choose the color you want but make sure to use appropriate resistors. You may not want full brightness and sure you don’t want magic smoke.
R1, R2, R11, R12, R15: 3.3K ohm, 0805.
R3: 330 ohm, 0805 (value may change – double check LM317 voltages).
R16: 10k ohm, 0805.
R6: 9/10W power resistor, not needed in my case.
R14: 1.2k ohm, 0805.
T1, T2, T3, T4, T5, T6: binding posts with 4mm hole. You may want some red ones for the positive lines and a black one for GND.
U1: LM-317, through hole. There should be enough space for a heatsink.
U2: TPS2513 from Texas Instruments. If you don’t have them, look up the datasheet and solder appropriate resistors on D+ and D- pins of the USB ports.
X1, X2: USB female connectors, through hole.
2 layer board of 3.95x3.94 inches (100x100mm). $77.65 for three.

Charge Booster - DCP Enumerator/USB Wrapper [Final]
BOM: TPS2513
Proper chip is TPS2514 which is single channel DCP enumerator chip, but digikey doesn’t carry it, the TPS2513 (dual channel) at digikey is cheaper than the TPS2514 at Mouser anyway
2 layer board of 0.8x0.69 inches (20x18mm). $2.75 for three.
This device also acts as a USB Wrapper and prevents Juice-Jacking as the data connection no longer reaches the charging port data pins
