ESP8266 NodeMCU + MAX232 RS-232 ESP-Link Serial Wifi Gateway Kit NO HEADERS
Product Description
*** Perfboard and headers NOT Included - Includes NodeMCU + Max232 Module Only***
ESP8266 NodeMCU Development board + RS232 - TTL Module
Particularly useful for creating a Wifi-RS232 Serial gateway using the free ESP-Link firmware.
Interface your microcontroller to RS232-level signals quickly and easily. RS-232 signals use voltages too high for any common microcontroller to interface with directly. Simply connect the 4-pin header on this module to your TX/RX, and power+ground pins and this problem is solved.
Standard DB-9 (Female) connector.
Works at both 5V and 3.3V (So Arduino, ESP8266, ESP32, STM32, Raspberry Pi, etc are all compatible)
Consider the excellent ESP-Link firmware for ESP8266 to create a WiFi - RS232 serial gateway. Easy to interface to our NodeMCU boards available here:
We offer 2-packs of the MAX232 modules here:
