WiFi Boards

You can connect up to 5 WiFi throttles. For the standard Mega board, we recommend the Conductor-Friendly Makerfabs WiFi shield below. Keep in mind you can also purchase a Mega+WiFi board online that has both a Mega clone and an ESP8266 built onto the same board. However, you will have to upload new firmware to that board, so that would be a Tinkerer option. See the Mega+WiFi page

Warning

Please be aware that the Espressif firmware provided with your device may not immediately work with EX‑CommandStation as there are many different versions which behave quite differently.

We highly recommend upgrading or downgrading to the “NonOS AT” version 1.7.4 available on our ESP8266 (WiFi Boards) download page prior to reaching out for support from the team.

For more information on how to configure your Command Station to use the boards below, see Wifi Setup

• Makerfabs ESP8266 WiFi Shield (recommended)
• Duinopeak ESP8266 WiFi Expansion Board
• ESP-01 and ESP-01s
• WangTongze Board
• Mega+WiFi Combo Board
• SparkFun Thing Plus (ESP32)
• ESP32_Ant-01 Breakout and Development Board (ESP32)
• HC-12 Wireless Bridge

Note

This is NOT to make a connection to JMRI. Use a USB cable instead. The WiFi and Ethernet solutions are designed to allow throttles to connect directly to the EX‑CommandStation without the need for any other software such as JMRI. While using a WiFi/Ethernet connection to JMRI will work, the overhead required internally will slow performance, take up valuable system memory, and prevent broadcast messages for sensors and power state.
