tinyHATs
A tinyHAT is a plug-in expansion board that stacks directly on top of the tinyCore ESP32-S3 using stacking pin headers, adding new hardware capabilities without any breadboarding or external wiring. Each HAT connects through a set of stacking headers that carry power, ground, and the GPIO signals the HAT needs — just seat it firmly and start coding.
