Page 3: What Is Esp32-Gateway
1. What is ESP32-GATEWAY ESP32-GATEWAY is a mature Open Source Hardware development board that incorporates n ESP32 module. The ESP32-GATEWAY board is designed and manufactured by Olimex, while the ESP32 module is designed and manufactured by Espressif systems. The ESP32 modules are extremely popular WIFI/BT modules due to their size, price, and very good documentation. -
Page 4: Esp32-Gateway Variants
Notice that older hardware revisions came with USB micro connector and require USB micro cable. The computer needs software compatible with ESP32 modules. Most commonly used tools are ESP- IDF and Arduino IDE with ESP32 package. You can use ESP32-GATEWAY with any software tool that supports the main ESP32 module. -

(uA) using the ESP32 power saving modes. The absolute maximum power ESP32-GATEWAY can draw from the power supply would be the determined by the maximum input of the regulator on the power input line. Of course, consider that on- board peripherals and the main module would use some of that current. -

◦ No. We updated the design with USB type C connector in 2024. It is the more popular connector nowadays. • I have ESP32-GATEWAY and it appears Ethernet is generating a lot of noise. How can I lower the noise? ◦ In hardware revisions prior to revision H, this might be caused by bigger than needed driver strength set by the software on the Ethernet clock pin (GPIO17). Lower the drive strength of... -
