Searching library for: "ESP32 DevKit carrier-board header or development board style part suitable for plugging an ESP32 DevKit module into female headers on a custom PCB. Need accessible GPIO pins including GPIO2 GPIO5 GPIO12 GPIO13 GPIO14 GPIO18 GPIO19 GPIO23 GPIO25 GPIO26 GPIO27 GPIO32 GPIO33 plus VIN 5V and 3.3V and GND. Prefer through-hole headers or devkit footprint representation for a carrier PCB."
