README

DisProg™ es una placa de adaptador USB a serie que se fundamenta en el popular chip CP2102N, incluyendo un circuito de restablecimiento automático ESP32. A diferencia de los módulos económicos que puedes encontrar en Aliexpress, este adaptador destaca por su confiabilidad y versatilidad simultánea. Su confiabilidad se deriva del uso de un conocido chip de adaptador USB a serie proveniente de un proveedor reconocido, y su versatilidad radica en la inclusión del circuito de restablecimiento automático ESP32 IO & EN, eliminando la necesidad de implementarlo en la placa de destino.
Otro punto a favor de DisProg™ es su regulador de voltaje integrado de 3.3V y 500mA, capaz de alimentar el dispositivo que estás programando. Como opción adicional, puedes conectar un cable JST personalizado que facilita la programación segura de relés Shelly sin depender de la alimentación principal. Esto sitúa a DisProg™ como uno de los mejores adaptadores USB/serie para cargar el firmware de tus dispositivos con Tasmota o ESPHome.

Questions
How big is the DisProg PCB?
It measures 35 × 18.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DisProg use?
24 parts, built around the CP2102N-EK, USBLC6-2P6 and UMH3N. 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 DisProg KiCad files?
From the disgran/DisProg repository on GitHub, at the commit this page was made from: the board is DisProg.kicad_pcb and its schematic DisProg.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DisProg design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
