A board file for the Elecrow CrowPanel 7.0" (DIS08070H, ESP32-S3-WROOM-1-N4R8): 800x480 through mipi_rgb, GT911 on the ESP32-S3's USB pins (elecrow_usb_phy.h frees them, behind a flag only this board sets), the Guition's vertical sizes across a wider page, no rotation. Its 4 MB of flash take the CYD's budget: a partition table of the component's (smart_display: partitions: 4mb_wide_slots, 1,984 KB slots), the icon fonts at 2 bits a pixel and the TLS client only bring the firmware to 1,865,440 bytes, 91.8 % of a slot, with camera images kept. docs/ELECROW.md has the numbers and the trade. The add-on reads a large board's name from the type sensor's value, the editor offers the board under New screen and draws the wide preview, tools/check.sh builds it with the budget, render_topbar and capture_ui take the panel's size. Firmware 0.2.79; the CYD image is unchanged (1,633,760 bytes). This fork builds from gittea.trippedonmy.name/Xandrossian/homeassistant_espscreen: the packages, the fonts, the component and the add-on repository point there instead of GitHub.

// The Elecrow CrowPanel 7.0" wires its GT911 touch I2C to GPIO19 and GPIO20, the ESP32-S3's USB D- and D+. The ROM
|
|
// leaves the USB_SERIAL_JTAG PHY on those pads, and ESP-IDF's I2C driver cannot take them back: the bus reads as
|
|
// "I2C software timeout" and the touch never answers (esphome/esphome#15356, ESPHome 2026.3+). This runs before any
|
|
// ESPHome component (a static constructor at priority 101): the PHY lets the pads go, and both become plain GPIOs
|
|
// with their pull-ups, as the I2C driver expects to find them. The board's USB-C port is a CH340 on UART0, so nothing
|
|
// is lost.
|
|
//
|
|
// ESPHome includes every header of the component in every build, so the code is behind a flag only the Elecrow's board
|
|
// file sets (`-DESP_SCREENS_FREE_USB_PADS=1`, packages/boards/elecrow-crowpanel7.yaml): the CYD has no such peripheral,
|
|
// and the Guition, an ESP32-S3 too, keeps its USB.
