esp32MX-E: High-quality ESP32 development board with extensive connectivity and multiple power options

esp32MX-E is a multifunctional ESP32 development board that supports functions such as Ethernet and USB Type C. It's designed with ease of integration in mind, so you can use it to simplify and speed up the development of your own custom boards. We have been designing and manufacturing electronic boards and modules for over 15 years, and this experience allows us to minimize costs, reduce risks and ensure long-term availability by using standard, high-quality components from well-known manufacturers.

The esp32MX-E features an advanced power circuit that accommodates multiple inputs, provides 3.3 V and 5 V outputs, and delivers over 2 A to the user. It features 3.3 V and 5 V high current switch mode regulators to ensure low power consumption and high efficiency. Power can be supplied via the USB C connector, 2.1 mm barrel connector, or external power pin. This allows the board designer to integrate the esp32MX-E as a daughter board with access to 3.3 V, 5 V and supply voltages via pin headers.

Designed for both standalone use and integration into larger projects, the esp32MX-E has two female headers so you can plug a small expansion board into them or use the esp32MX-E itself as a daughter board. All connectors, switches and LEDs are located on one side of the board, making it easier to design custom enclosures.
