ESP32 ESP-32 WROOM WIFI + BLE IoT Development Board (38Pin) CP2102

This is an IoT board which can be used as a client mode where collected sensor data can be sent to the server using WiFi protocol. Or, used as the main server to control Led, relay or any output that connected to this board. This board is fully supported by the Arduino IDE program.

Variant:
CP Version = CP2102 serial chip
CX Version = CH9102X serial chip
CH Version = CH340 serial chip

ESP32 = support On-board / Internal Antenna Only
ESP32-U = support External Antenna Only (*Need to buy extra external antenna)
ESP32S = support dual Onboard/ Internal Antenna and External Antenna
