This allows 3.5" LCDs with a 54-pin connector to be connected to an FPGA board with dual PMODs, using either 8-bit serial RGB or YUV422 modes.

BOM:
- R1, R3-R9: 10kΩ 0603 resistors
- R2: 10Ω 0603 resistor
- C1, C4: 10µF 6.3V 0805 capacitor
- C2: 220nF 10V 0603 capacitor
- C3: 1µF 50V 0805 capacitor
- U1: TPS61165DBV LED boost converter IC
- L1: 10µH A915AY-100M inductor
- D1: MBR0540 diode
- J1, J2: 2x6 2.54mm right angle THT header
- LCD1: 54-pin Molex 51296-5494 connector; LQ035NC111 LCD or equivalent
- JP1: 2x3 2.54mm straight THT header
For serial RGB operation, JP1 pins 1 and 2 (bit 0 on the PCB) should be shorted with a jumper.
Errata: C1 and R1’s labels are swapped on the PCB silkscreen, note the capacitor is 0805 (10µF) and the resistor 0603 (10kΩ) to tell these apart.
