Device	Comments
ESP32-WROOM-32	Can be flashed with a programmer.
ESP32-WROVER	Extra PSRAM is not yet supported. Can be flashed with a programmer.
ESP32-DevKitC v1 / ESP-32S	Flashing can be unreliable. Might need to press the 'boot' button or add a capacitor
NodeMCU ESP32 WROOM	Flashing can be unreliable. Might need to press the 'boot' button or add a capacitor

ESP32-CAM	Camera and extra RAM not yet supported. Difficult to flash. Requires an external flasher (or a different dev-board) to flash.
WeMos D1 R32	Wroom based. Supported.
M5 Atom Switch	Might need lower baud rates, and thus can't be flashed with the console.toit.io.
M5Core2	Uses the ch340 USB-to-serial chip, which needs a driver-update on macos. Read the discussion to see how to use its peripherals.
M5 Stamp-Pico	Requires an external flasher (or a different dev-board) to flash. Note that M5's ESP32-Downloader might use the CH92102 chip which requires a driver-update on macos. M5 also has a "Driver Installation" section on the USB Downloader page.
