README
readme.mdPicotronix: Pico-based driver for Tektronix vector displays.
Picotronix is an adapter board that can interface with Tektronix 603/604 series vector displays, and is capable of using the storage features if they are available.
It connects to the remote DB25 connector to provide all the inputs and controls, and can be interfaced over usb for PC control or directly run it's own visuals.
It also has two ESP-01-compatible pin headers for IO expansions to meet specific application needs.
Project Structure
Since this project is multi-domain (PC library, RP2040 Firmware, and KiCAD PCB),
the project is split up into respective subfolders. To facilitate communication between the Pico and
the PC, Cap'n Proto is used as a protocol exchange library generator.

Questions
How big is the Picotronix PCB?
It measures 97.8 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Picotronix use?
46 parts, built around the ADA4891-3ARZ, PCM1808PW and W25Q128JVSIQ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Picotronix KiCad files?
From the 5aji/picotronix repository on GitHub, at the commit this page was made from: the board is pcb/picotronix.kicad_pcb and its schematic pcb/picotronix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Picotronix design in my own project?
Its repository states no licence, so its author keeps all rights: ask 5aji before reusing the design.
