Overview
IRview is an open-source printed circuit board by ImShyMike, from the ImShyMike/IRview repository on GitHub, published under the MIT licence. It is a 2-layer board of 54 × 77.2 mm with 22 parts on 45 nets, routed with 177 tracks and 32 vias.
It is built around the ESP32-S3-WROOM-1-N8 and AMS1117-3.3. Its parts include 6 switches, 4 resistors, 4 connectors, 2 capacitors and 2 ICs. It belongs with the power boards and the ESP32 boards of this library.

README
README.mdIRview
A tiny thermal camera with a screen. It's powered by an ESP32-S3-WROOM-1 with 8mb of PSRAM and 8mb of RAM and uses a Melexis far infrared thermal sensor array with a 32x24 resolution that can measure temperatures from -40 to 300°C and has a 55° FOV and uses a PowerBoost 1000 as a BMS that enables it to use a LiPO battery.
The 320x240px screen at the front is used to display the image data, battery and temperature readings and the buttons are used to switch modes. All pin headers are exposed, even when the case is assembled, to help with debugging. It does not include an usb to UART chip so programming must be done using the exposed TX/RX pins with an external programmer.
Why
Thermal cameras are very expensive and have always felt like magic to me so why not try to make my own on a budget (while also finding out that IR sensors are way more expensive than i expected and that AliExpress always saves the day) :D

Questions
How big is the IRview PCB?
It measures 54 × 77.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IRview use?
22 parts, built around the ESP32-S3-WROOM-1-N8 and AMS1117-3.3. 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 IRview KiCad files?
From the ImShyMike/IRview repository on GitHub, at the commit this page was made from: the board is PCB/IRview/IRview.kicad_pcb and its schematic PCB/IRview/IRview.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IRview design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
