About the Fiberboard PCB

Fiberboard is an open source ESP32 PCB design by nguyenduchan, published on GitHub. It is a 2-layer board measuring 118 × 84 mm, with 116 components from 53 distinct parts.

Its main chip is the ESP32-DevKitC-32E, from the ESP32 family. Other key parts include the XL1509-5.0, AMS1117-3.3, PC817 and MAX485E. By type, the board carries 38 resistors, 25 diodes, 20 capacitors, 8 connectors, 7 inductors and 6 ICs.

From the project

Fiberboard là bo mạch điều khiển logic tích hợp (AIO), không có driver stepper Nema. Dùng cho bơm DC, cấp liệu feeder, báo vật thể lạ và mini filler.

Trên bo có đế cắm ESP32-DevKitC (nạp phần mềm nhúng qua USB trên module). Nguồn vào 9–24 VDC. Hai kênh quang sợi POF 1 mm (AFBR) gắn trên PCB. Đầu ra relay và van solenoid, RS485. Mỗi giắc vào/ra có đèn SMD 0805 sát cọc. Trong cột nguồn có đèn debug: D27 sáng khi +24 V sau bảo vệ còn điện, D25 khi buck ra +5 V, D6 khi LDO ra 3,3 V. Không có header OLED trên bo.

Fiberboard: common questions

What microcontroller does the Fiberboard use?

The Fiberboard is built around the ESP32-DevKitC-32E, from the ESP32 family.

How big is the Fiberboard PCB?

The Fiberboard measures 118 × 84 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Fiberboard?

116 components, from 53 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 Fiberboard design files?

From the nguyenduchan/fiberboard 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 Fiberboard design in my own project?

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

Can I test firmware for the Fiberboard 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.
