+This is the CircuitPython **Zephyr-port build** for the Adafruit CLUE. The CLUE has an nRF52840, a 1.3-inch color display, buttons, and onboard motion and environmental sensors. This build is separate from the [standard CLUE CircuitPython download](/board/clue_nrf52840_express/); use that page if you want the established nRF port.
+
+The Zephyr port is experimental, and its available modules and flashing process may differ from the standard CLUE build. See the [CLUE hardware guide](https://learn.adafruit.com/adafruit-clue) before programming the board.

+The ESP32-C5-DevKitC-1 is Espressif's development board for the ESP32-C5-WROOM-1 module. This N8R8 variant has 8 MB of flash and 8 MB of PSRAM. The ESP32-C5 provides dual-band Wi-Fi 6, Bluetooth Low Energy, and an IEEE 802.15.4 radio for Thread and Zigbee development.
+
+Most GPIO pins are broken out along both sides of the board for breadboard or jumper-wire prototyping. It includes USB-C connections for power, programming, and serial communication, plus BOOT and RESET buttons. Check the [Espressif user guide](https://docs.espressif.com/projects/esp-dev-kits/en/latest/esp32c5/esp32-c5-devkitc-1/user_guide.html) for the correct port and flashing procedure.

+This build is for a **custom ESP32-S3 drop-in board** associated with the IKEA ALPSTUGA air-quality sensor. It is not firmware for the stock IKEA sensor. The [CircuitPython board definition](https://github.com/adafruit/circuitpython/blob/main/ports/espressif/boards/ikea_alpstuga_esp32_s3/mpconfigboard.h) identifies 4 MB of flash and 2 MB of PSRAM.

+The nRF54L15 Tag is a compact, battery-powered prototyping platform built around Nordic's nRF54L15 wireless SoC. Its two antennas support Bluetooth Channel Sounding experiments, making the tag useful for asset-tracking and proximity projects. It also has a user button and RGB LED.
+
+This CircuitPython download is an experimental Zephyr-port build. Programming and debugging the tag require compatible external hardware, such as an nRF54L Series development kit connected to its debug header. Follow [Nordic's getting-started guide](https://www.nordicsemi.com/Products/Development-hardware/nRF54L15-Tag/GetStarted) for the hardware setup.
