From the project
Kicad design files for prism laser direct imager using up5k FPGA and ESP32
KiCad design files for the Hexastorm, an open-hardware prism laser direct imager. This project utilizes an ESP32-S3 and an iCE40 UP5K FPGA to achieve high-resolution, high-speed laser exposure.
The design files are organized into two primary categories:
MCU: ESP32-S3 (N32R8V) utilizing 8MB Octal PSRAM for rapid image buffering. FPGA: Lattice iCE40 UltraPlus 5k (UP5K) for nanosecond-level laser modulation and real-time synchronization with the prism index pulses. Vision & Alignment: Features a dedicated 24-pin FPC camera connector supporting the OV2640 sensor for precise laser alignment.…
