Description
Minimum Quantity Required: 10 chips.
The ESP32-D2WD has all the great features of the ESP32-D0WD plus adds 2 Mbytes of embedded on-chip flash. This embedded flash means that the entire application can be run on-chip with no external flash needed. The added flash also makes this compact 5x5 chip a powerhouse for the wearable's market or any other application where small size is needed.
The ESP32-D2WD also features dual microprocessors, (one for normal operation and one for low-power sleep mode), and has the combo Bluetooth (BT 4.2 and BLE) and Wi-Fi radios.
