ESPboy:Breadboard - Homebrew STEM Gadget, Retro Gaming, Multi-tool

Let's make a ESPboy:Breadboard -- a multi-tool for retro gaming and software development, using just a few parts for about $8 in 15 minutes.

It will be compatible with the original ESPboy, ESPboy:Kit, ESPboy:DIY, ESPboy software, ESPboy WebAppStore and WiFiAppStore (install "AppStore2 (OTA2)" from WebAppStore to get access to WiFiAppStore directly from the ESPboy using WiFi connection).
