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-DevKitC v4	All dual core models (but not the ESP32-SOLO-1) are supported. However, extra features (like PSRAM) might not be supported.
ESP32-Ethernet-Kit-A_v1.2	This device exposes two COM ports. The first one is for JTAG and the second one is for flashing. When user selects the first COM port provisioning freezes at 0%. The user must restart the process and select the second COM port which works.
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.
PyCom GPy	Follow special steps to flash
Heltec WiFi Kit 32	Only supported by OSS Toit. Requires sdkconfig change to support 26MHz frequency (search for XTAL_FREQ)
FireBeetle ESP32-E	Uses the ch340 USB-to-serial chip, which needs a driver-update on macos.
Olimex DevKit-LiPo	Open-hardware, with LiPo battery support.
Olimex ESP32-POE-ISO	Open-hardware. Requires lower baud rate when flashing. Ethernet might work with OSS Toit, but requires an sdkconfig change.
