Handheld GS: common questions

What microcontroller does the Handheld GS use?

The Handheld GS is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Handheld GS PCB?

The Handheld GS measures 65 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Handheld GS?

99 components, from 54 distinct parts. The full bill of materials is listed on this page.

Where can I download the Handheld GS design files?

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

Can I use the Handheld GS 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 Handheld GS 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.
