This module is safe and reliable and can be extended to a variety of applications.
The module has 38 pins and has more functions than the 30-pin module. Narrower width, compatible with the circuit board
Support Lua procedures, easy to develop. The AP, STA, and AP+STA modes are supported.
The board uses 2.4ghz dual-mode Wi-Fi and Bluetooth chip ESP-Wroom-32 and 40nm low power technology.
1.ESP32 Split-line board GPIO 1-in 2-38pin narrow ESP32 ESP32 ESP-Wroom-32 microcontroller development board
Important: Only compatible with 38-pin narrow hole and no mounting hole versions of the ESP32 development board, not applicable to other versions.
GPIO 1 INT0 2: The splitter expands one GPI0 pin of the ESP32 development board to two, making it easy for users to reuse all pins in smart home projects. Good alternative bread board.
2. Type connection: pin connector box screw terminal. Just choose them for your purpose.
Double-layer PCB: The expansion board is double-layer. A pin is attached on both sides. Therefore, the circuit is stable and reliable, and there will be no bad circuit contact and unstable signal transmission.
Updated version: Compared to previous versions, this version of the board has been fully welded. You don’t need to weld the parts yourself, so it’s very easy to use.
