Product Information

Product Description

Authorized North America Distributor Stamp

The ESP32-S0WD has a single-core microprocessor, making it a money saving option for applications where line power is available. Unlike the rest of the ESP32 family, the ESP32-S0WD lacks the second microprocessor used for low power modes, but otherwise has all the same great features and peripherals. This single core option is perfect for gateway applications where line power is available. This combo chip has both Bluetooth (BT 4.2 and BLE) and Wi-Fi. .

ESP32-S0WD Key Features

  • Small 5 x 5 mm package
  • 2.4 GHz Wi-Fi
  • Bluetooth 4.2 and BLE
  • Fine resolution clock gating
  • Dynamic power scaling
  • Built-in Antenna Switches

These features allow the support of leading industry smart home standards including Apple HomeKit.
