Serial Adapter Module for ESP-01
3 in stock
This is an adapter for easier interfacing with the ESP8266 ESP-01 WiFi modules. ESP8266 ESP-01 are WiFi modules that can be used for wireless communications. They operate at 3.3V for power and require up to 170mA of current.
If you are using the ESP-01 with a 5V MCU, the current requirements are outside what an Arduino or similar MCU can supply directly from their small on-board 3.3V regulator. This adapter can be powered off of 5V-12V and supplies well regulated 3.3V to the ESP-01 socket.
It also provides level shifting for the TX/RX lines which is necessary for the safe operation of this module with a 5V MCU since the I/O of the ESP-01 is not 5V tolerant.
