Add an Upduino 2.0 FPGA board and create the ultimate hackable badge with 3.5" LCD, directional buttons, audio and PMOD for expansion! Based on the iCE40 UP5K FPGA, it’s fully compatible with the open source “icestorm” toolchain.

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.
