NEO-6502

The NEO-6502 is a modern retro single-board computer that pairs a classic WDC 65C02 processor with a Raspberry Pi RP2040 microcontroller, bridging vintage 8-bit computing with contemporary hardware. It's a love letter to the 6502 era — fully programmable in BASIC, assembly, and C, with real modern I/O.

Key Features

• CPU: WDC 65C02 @ up to 6.25MHz (clocked by RP2040)
• Co-processor: Raspberry Pi RP2040 (dual-core Cortex-M0+ @ 133MHz) — handles I/O, storage, USB, and graphics
• RAM: 64KB (classic 6502 address space) + RP2040 SRAM for system tasks
• Storage: MicroSD card slot
• Display: HDMI output via RP2040 PIO (text and bitmap graphics modes)
• USB: USB-A host port for keyboard; USB-C for power and programming
• Audio: Mono audio output
• Expansion: GPIO header for peripherals and add-on boards
• Firmware: Built-in NEO-6502 OS with BASIC interpreter, file system, and API
• Programming: BASIC, 65C02 assembly, C (via RP2040 SDK bridge)

What's Included

• 1× NEO-6502 board

Ideal For

Retro computing enthusiasts, educators teaching 6502 assembly, hobbyists building classic-style games and demos, and developers who want to explore 8-bit architecture with modern connectivity. A perfect blend of nostalgia and practicality.
