MiniMain: an ESP32-S2 Feather for haunted attraction props
MiniMain ESP32-S2 is a Feather-shaped main board contains an ESP32-S2 for the main microcontroller. It contains 4 MB of flash + 2 MB of PSRAM along with native USB.
This board is designed for use in haunted attraction props as it includes an optoisolated input that allows it to be triggered by another prop controller operating at 12V. This is where the MiniMain deviates from a standard Adafruit Feather: it does not include support for battery operation. (There is also one additional pin broken out in standard 2.54mm pitch format designed for a servo.)

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
