From the project
A Python-based hardware description language for PCBs for higher-level (block-diagram / system-architecture level) PCB design through libraries of directly reusable subcircuit generators.
subcircuit generator library based hardware description language for circuit board design
Polymorphic Blocks is an open-source, Python-based hardware description language (HDL) for schematic-equivalent design of printed circuit boards (PCBs). Its library of components provide a high-level abstraction for circuit design while subcircuit generators automate the calculation of fine details. Abstract component interfaces enable these libraries to be general across applications and component vendors.

IotThermalCamera: common questions
What microcontroller does the IotThermalCamera use?
The IotThermalCamera is built around the mcu.ic, from the ESP32 family.
How big is the IotThermalCamera PCB?
The IotThermalCamera measures 30 × 95 mm, has 2 copper layers and is 3.66 mm thick.
How many components are on the IotThermalCamera?
119 components, from 119 distinct parts. The full bill of materials is listed on this page.
Where can I download the IotThermalCamera design files?
From the BerkeleyHCI/PolymorphicBlocks repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the IotThermalCamera design in my own project?
Yes, under the terms of its BSD-3-Clause license, which BerkeleyHCI chose for the repository.
Can I test firmware for the IotThermalCamera without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
