Each material pulled apart from a board Inky built on it, layer by layer as its file states
Every board, built by Inky.
The rigid board nearly everything starts on, and the one every heypcb board gets unless you name another.
ESP32-S3 dev board
The brief: “Design an ESP32-S3 dev board: USB-C, LiPo charger, two buttons, an RGB LED and pin headers. Green FR-4, fully routed, DRC clean.”
Order it from heypcb, or download its files.
A board that bends: wearables, probes, and the cable that folds into the case, under a polyimide coverlay.
LED arc
The brief: “A flexible LED arc on polyimide flex.”
IMU tail
The brief: “A flexible IMU tail on polyimide flex.”
Display adapter
The brief: “A flexible display adapter on polyimide flex.”
Temperature probe
The brief: “A flexible temperature probe on polyimide flex.”
Download its files for a flex fab. Ordering from heypcb is FR-4 only.
One copper layer on a thin thermal dielectric over an aluminium base, for LEDs that run hot.
6 × 6 LED panel
The brief: “A 6 x 6 LED panel light on aluminium.”
LED light bar
The brief: “A 12-LED light bar on aluminium.”
3 × 3 LED light
The brief: “A 3 x 3 LED light on aluminium.”
LED star
The brief: “A round LED star on aluminium.”

A copper base raised under each part's thermal pad, so the heat goes straight into the metal.
3 W LED engine
The brief: “Six 3 W LEDs on a direct-heatsink copper core.”
Six-LED ring
The brief: “Six 3 W LEDs in a ring on a copper core.”

A steady, low-loss ceramic laminate for RF lines, amplifiers and antennas.
Low-noise amplifier
The brief: “A 0.6–6 GHz low-noise amplifier on Rogers RO4350B.”
2.4 GHz power amplifier
The brief: “A 2.4 GHz power amplifier on Rogers RO4350B.”
Download its files for a fab that stocks Rogers. Ordering from heypcb is FR-4 only.
The lowest-loss laminate here, for radar and antennas at tens of gigahertz.
24 GHz radar
The brief: “A 24 GHz motion-sensing radar on PTFE.”
3-way RF splitter
The brief: “A resistive 3-way RF splitter on PTFE.”
Download its files for a fab that stocks PTFE. Ordering from heypcb is FR-4 only.
Not a laminate but a way of building FR-4: laser microvias in the balls of a fine-pitch chip, on a board the size of a thumb.
FPGA stick
The brief: “A thumb-sized FPGA stick on 6-layer HDI.”
Audio board
The brief: “An STM32F411 audio board on 6-layer HDI.”
Download its files for an HDI fab. Ordering from heypcb is FR-4 only.
