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.

Gse control node: common questions

What microcontroller does the Gse control node use?

The Gse control node is built around the ESP32-S3-WROOM-1U, from the ESP32 family.

How big is the Gse control node PCB?

The Gse control node measures 65 × 95 mm, has 4 copper layers and is 1.5842 mm thick.

How many components are on the Gse control node?

183 components, from 48 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gse control node design files?

From the Queens-Rocket-Engineering-Team/gse-control-node repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Gse control node design in my own project?

The repository has no license, so all rights stay with Queens-Rocket-Engineering-Team. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Gse control node without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
