Iasis
About the Iasis PCB
Iasis is an open source Raspberry Pi PCB design by hydazz, published on GitHub under the Apache-2.0 license. It is a 6-layer board measuring 130 × 100 mm, with 636 components from 100 distinct parts.
Its main chip is the RP2354B, from the Raspberry Pi family. Other key parts include the USB7206CT/KDX, SN74AUP1G08DCKR, HD3SS3212IRKSR, TPD4E02B04DQAR and TPD6S300ARUKR. By type, the board carries 276 resistors, 232 capacitors, 73 ICs, 24 transistors, 10 connectors and 7 diodes.
From the project

Iasis: common questions
What microcontroller does the Iasis use?
The Iasis is built around the RP2354B, from the Raspberry Pi family.
How big is the Iasis PCB?
The Iasis measures 130 × 100 mm, has 6 copper layers and is 1.5688 mm thick.
How many components are on the Iasis?
636 components, from 100 distinct parts. The full bill of materials is listed on this page.
Where can I download the Iasis design files?
From the hydazz/iasis repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Iasis design in my own project?
Yes, under the terms of its Apache-2.0 license, which hydazz chose for the repository.
Can I test firmware for the Iasis without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
