ESP32 DevKitC 32U

The ESP32 DevKitC 32U is a micro USB ESP32 development board built on the ESP32-WROOM-32U module. It has full Wi-Fi and Bluetooth, but instead of an onboard PCB antenna it has an IPEX connector for an external antenna. That lets you mount the antenna outside an enclosure or away from metal for a more reliable connection.

Note: This board needs an external antenna to use Wi-Fi or Bluetooth. Add the 2.4GHz 3dBi antenna with SMA to IPEX connector, or buy the ESP32 DevKitC 32U + 2.4GHz Antenna bundle.

Key features

• ESP32 dual-core Xtensa LX6 at up to 240MHz
• 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 4.2 with BLE
• IPEX connector for an external antenna
• Micro USB for programming and power
• GPIO with ADC, DAC, capacitive touch, UART, SPI, I2C and PWM
• Works with Arduino IDE, ESP-IDF, MicroPython and ESPHome

Applications

• Devices in metal or sealed enclosures
• Smart home automation and ESPHome devices
• Environmental monitoring and remote sensors
• Robotics, drones and other projects where the board sits away from the router
