About the FluxDrive PCB

FluxDrive is an open source ESP32 PCB design by dimitrihilverda, published on GitHub. It is a 4-layer board measuring 60 × 54.5 mm, with 89 components from 32 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N16R8, from the ESP32 family. Other key parts include the 74LVC14A, 74LVC07A, TPS259531, TLV62569DBVR and USBLC6-2SC6. By type, the board carries 59 resistors, 14 capacitors, 7 ICs, 3 connectors, 3 diodes and 2 switches.

It belongs with the dev boards & breakouts, rf & radio and iot & wireless designs in this gallery.

From the project

An Amiga floppy drive emulator built around one ESP32-S3: no Gotek, no second microcontroller. It plugs into the A500's internal floppy connector, holds a disk image in PSRAM and generates the MFM flux stream itself. Disk images come from the GTi touchscreen over ESP-NOW, or from

An Amiga floppy drive emulator built around one ESP32-S3: no Gotek, no second microcontroller. It plugs into the A500's internal floppy connector, holds a disk image in PSRAM and generates the MFM flux stream itself. Disk images come from the GTi touchscreen over ESP-NOW, or from a phone over WiFi. The design starts from Mez's OMEGAWARE FluxDrive hardware design document (see Credits).

FluxDrive: common questions

What microcontroller does the FluxDrive use?

The FluxDrive is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the FluxDrive PCB?

The FluxDrive measures 60 × 54.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the FluxDrive?

89 components, from 32 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 FluxDrive design files?

From the dimitrihilverda/FluxDrive 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 FluxDrive design in my own project?

The repository has no license, so all rights stay with dimitrihilverda. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the FluxDrive 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.
