Neo6502PC-PWR: common questions

What microcontroller does the Neo6502PC-PWR use?

The Neo6502PC-PWR is built around the CH32V003F4P6(TSSOP20), from the RISC-V family.

How big is the Neo6502PC-PWR PCB?

The Neo6502PC-PWR measures 46 × 75 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Neo6502PC-PWR?

64 components, from 35 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Neo6502PC-PWR design files?

From the OLIMEX/Neo6502pc repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Neo6502PC-PWR design in my own project?

Yes, under the terms of its GPL-3.0 license, which OLIMEX chose for the repository.

Can I test firmware for the Neo6502PC-PWR without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
