About the Iris brow PCB

Iris brow is an open source PCB design by HeyPCB, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 116 × 12 mm, with 16 components from 12 distinct parts.

Other key parts include the VL53L1CXV0FY/1 and APDS-9306-065. By type, the board carries 6 capacitors, 3 resistors, 2 ICs, 2 microphones, 2 test points and 1 connector.

It belongs with the sensors, robotics & motion and audio designs in this gallery.

From the project

Iris Brow: forehead sensor strip of the Iris robot head. VL53L1X distance, APDS-9306 light, two I2S microphones 108 mm apart, touch pads, on a brow-shaped board. 2-layer KiCad 10 board, DRC-clean, fab-ready.

The forehead sensor strip of Iris: a VL53L1X distance sensor for vergence, an APDS-9306 light sensor, two I2S microphones 108 mm apart for sound direction and touch pads, on a brow-shaped board.

Part of Iris, the human-eyed robot head, HeyPCB's open robot boards. Designed end to end with the HeyPCB method on KiCad 10 (headless pipeline, Freerouting 2.4.1); every number below is measured on the files in this repository. Mentions of ./run.sh, docs/rules/, blocks/ or parts/ refer to the heypcb-kicad SDK that produced them.
