README

PIAA, inspired by the CIAA project.
The PIAA is a open source printed cicuit board design for use in industrial settings where electromagnetic interference is of great concern. The on board processor is intended to be the RP2040 contained in the Raspberry Pi Pico package
Features:
- All I/O except for GPIO header come with extensive EMI protection.
- Wide temperature range components.
- 1 RS485 peripheral using MAX3072E.
- 6 Digital outputs with PWM capabilities.
- 4 digital inputs.
- Powered be 6-24V input.
- 8 additional GPIO on header with SPI, I2C, UART, PWM, PIO capabilities. This header is connected to GPIO0 through GPIO7.
- Regulated 3.3V and 5V outputs.
- Grounded padding on sides of Proant wifi/bluetooth antenna to potentially increase antenna gain (not tested).
Kicad: Project setup
This project was made entirely with Kicad.
Download external dependencies with:
git submodule update --initFurther setup
I'd believe the project should be set automatically since I've taken care to include all libraries as "Project" libraries, not "Global". In any case, if that fails you may follow the steps detailed here to setup any symbol, footprint and 3D model libraries that may be needed to work or visualize the PIAA.
-
After initializing git submodules with external symbol and footprint libraries (with
git submodule update --init) follow the symbol installation instructions at this link and use the footprint in the folder [RP-Pico Libraries](./submodules/KiCad-RP-Pico/RP-Pico Libraries). -
Setup
piaalibsymbol and footprint libraries. They are located under design/lib/piaalib. The steps to adding these libraries are the same as with the RP-Pico libraries.

Questions
How big is the Piaa PCB?
It measures 98.6 × 53.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Piaa use?
104 parts, built around the MAX3072EESA+, MCP1416-E/OT, LM2596S-5.0 and FQT13N06L-VB. 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 Piaa KiCad files?
From the soypat/piaa repository on GitHub, at the commit this page was made from: the board is design/piaa/piaa.kicad_pcb and its schematic design/piaa/piaa.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Piaa design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
