Overview
PEEP is an open-source printed circuit board by Rivercraft911, from the Rivercraft911/PEEP repository on GitHub, published under the MIT licence. It is a 4-layer board of 12.1 × 8 mm with 15 parts on 34 nets, routed with 103 tracks and 13 vias.
It is built around the VSOP38338 and VEMD10940F. Its parts include 5 capacitors, 3 resistors, 3 ICs, 1 diode and 1 connector. It belongs with the STM32 boards of this library.

README.mdPEEP
The World's smallest remote-controlled keystroke injection device... A 12.06 × 8 mm infrared-controlled USB keyboard.
Hardware
- Four-layer, 0.8 mm PCB with a direct USB-A edge connection
- STM32F042G6 Cortex-M0 with crystal-less USB Full Speed
- VEMD10940F photodiode and VSOP38338 38 kHz IR receiver
- Factory USB DFU bootloader; bridge BOOT0 to 3.3 V for recovery
Software
An IR burst starts the stored macro. PEEP sends standard USB keyboard reports, ignores IR while the macro runs, then re-arms after 250 ms of idle receiver time. Plugging it in does not start the demo.

There is no Windows companion or packet-upload protocol yet.
The firmware builds and passes native tests.
Use PEEP only on systems you own or have permission to test.

Questions
How big is the PEEP PCB?
It measures 12.1 × 8 mm and has 4 copper layers, 0.8 mm thick.
What parts does the PEEP use?
15 parts, built around the VSOP38338 and VEMD10940F. 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 PEEP KiCad files?
From the Rivercraft911/PEEP repository on GitHub, at the commit this page was made from: the board is PCB/peep/peep.kicad_pcb and its schematic PCB/peep/peep.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PEEP 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).
