All-in-one Intellivision FujiNet cartridge: one board carrying both halves of the INTV FujiNet stack —

- RP2354A (RP2350A + 2 MB stacked flash, QFN-60) running the Minty-derived cartridge firmware from fujinet-firmware/pico/intellivision/firmware, built with -DPICOBOARD=fujicard. It emulates the cartridge on the CP-1610 bus (GPIO0–15 = AD0–AD15 wired directly to the 5 V cart edge — RP2350-family pads are 5 V-tolerant with IOVDD = 3.3 V) and exposes the FujiNet mailbox at $9C00-$9F3F. - ESP32-S3-WROOM-1-N16R8 running the fujiversal-intv build of fujinet-firmware (./build.sh -e…

FujiNet-INTV-Rev0: common questions

What microcontroller does the FujiNet-INTV-Rev0 use?

The FujiNet-INTV-Rev0 is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the FujiNet-INTV-Rev0 PCB?

The FujiNet-INTV-Rev0 measures 58.2 × 78 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the FujiNet-INTV-Rev0?

77 components, from 37 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 FujiNet-INTV-Rev0 design files?

From the FujiNetWIFI/fujinet-hardware 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 FujiNet-INTV-Rev0 design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which FujiNetWIFI chose for the repository.

Can I test firmware for the FujiNet-INTV-Rev0 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
