openHASP runs on Adafruit's ESP32 Feather Boards and supports Adafruit's TFT Featherwing resistive touch screens. Build configurations and precompiled firmware binaries are available for these popular hardware combinations to help you get started quickly.

## Supported Boards

openHASP supports the following Adafruit Feather boards (and the many different versions and variations based on them)
openHASP supports the following Adafruit Feather boards (and the many different versions and variations based on them):

- Adafruit HUZZAH32 - ESP32 Feather (4MB Flash, No PSRAM)
- Adafruit ESP32-S3 Feather (4MB Flash, 2MB PSRAM)
- Adafruit ESP32 Feather V2 (8MB Flash, 2MB PSRAM)

These boards are virtually plug-and-play when combined with Adafruit TFT FeatherWing displays. Many of these boards come in versions with pre-soldered headers (no soldering required)

!!! note " Note" Don't use the Adafruit ESP8266-based Feather HUZZAH board as it lacks both sufficient memory and MCU power.

!!! note " Note" Boards with PSRAM are highly recommended, and required for image processing.

## Backlight

By default, the display is always on and at its maximum brightness. To control backlight dimming or sleeping, you need to solder the `LITE` pin to a PWM output pin (e.g., `GPIO 21`).
By default, the display is always on and at its maximum brightness. To control backlight dimming or sleeping, you need to solder the `LITE` pad on the TFT Featherwing to a PWM output pin on the Feather board (e.g., `GPIO 21` on the Adafruit HUZZAH32 - ESP32 Feather or `GPIO 37` on the Adafruit ESP32 Feather V2, as these are, respectively, the closest pins to the `LITE` pad).
