DOIT ESP32-32D Wi-Fi + BLE Module, 4MB (N4)

Details

DOIT surface-mount ESP32 module with the ESP32-D0WD dual-core chip, 4 MB flash, Wi-Fi, Bluetooth LE and a built-in PCB antenna. It is the bare module for soldering onto your own PCB, and is compatible with the ESP32-WROOM-32D footprint. It is not a development board and has no USB port. The marking on the module may read ESP32-32D or ESP-WROOM-32D. To program it, pull IO0 low at reset and use a USB-to-serial adapter. Design notes: use a 3.3 V supply that can deliver at least 500 mA. Keep metal and copper away from the antenna. The module is moisture sensitive (MSL 3), so solder it within 168 hours of opening the sealed bag.
