ESPboy DIY - Retro Gaming and Software Development Multi-tool

Let's make a simple DIY version of ESPboy -- 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 ESPboy1/ESPboy2 , ESPboy software, ESPboy WebAppStore and AppStore (install "AppStore2 (OTA2)" from WebAppStore to get access to AppStore directly from the ESPboy using WiFi connection).
