To program the board with the Arduino IDE select the 'ESP32 Dev Module' in the board manager.
This module comes preprogrammed as either a transmitter or a receiver. Both versions have identical hardware and can therefore also be programmed as both transmitter and receiver.
*Note: The pins on the board are directly connected to the ESP32 chip and are therefore only suitable for 3.3V signals.
