From the project

The GSE control node is the control PCB for GSE systems to integrate with launch control. This includes actuator control, fan control, and a load cell reading. This control node is used for control of the GSE equipment on the launch tower.

The GSE control node is the control PCB for GSE systems to integrate with launch control. This includes actuator control, fan control, and a load cell reading. This control node is used for control of the GSE equipment on the launch tower.

Control nodes use an ESP32S3-WROOM-1U microcontroller for systems control. This ESP32S3 communicates with an external control server to for remote control and data streaming over 2.4GHz WiFi. All commands are sent from the external server, as control nodes does not autonomously control any systems.
