README
README.mdESP32 Programmer
This is a USB-C programmer for ESP32 chips, including autoreset as documented by espressif. The pinout is compatible with the ESPFlash convention proposed by SuperHouse at https://www.superhouse.tv/espflash/ .
Additionally, 5V is exposed from the USB port (after the protection fuse) - this allows the ESP programmer to be used as a USB to serial module providing both 5V and 3.3V. The 5V can either be connected via a jumper wire (if the programmer is mounted vertically) or directly via a pin (if mounted horizontally)

Questions
How big is the Esp programmer PCB?
It measures 29 × 17.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp programmer use?
29 parts, built around the AP2112K-3.3, USBLC6-2P6 and BC847W. 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 Esp programmer KiCad files?
From the jnicolson/espprog repository on GitHub, at the commit this page was made from: the board is esp_programmer.kicad_pcb and its schematic esp_programmer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp programmer design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
