Hexstar 1U · CubeSat kit

Built for
near space.

A real 1U CubeSat kit for your desk, long-range field tests and stratospheric balloon flights. Flight-style boards, a LoRa radio and a pocket ground station, all in a 10 cm cube.

01 · Open it up

Every part.
Yours to see.

Four rails, four skeleton panels, a top plate with the GNSS patch and whip antenna. Everything comes apart with an M3 driver.

02 · Inside

Three boards.
One mission.

Radio on top, brain in the middle, power at the bottom. They're joined by a single 40-pin stack bus, exactly like flight hardware.

Layer 01 · Communications

Layer 03 · Underside

One cell.
Everything.

A single 18650 Li-ion cell under the EPS powers the whole stack, with protection, a fuse and a remove-before-flight key between it and the bus.

Near space · Stratosphere ready

Ready for
the edge of space.

Test it on your rooftop over long-range LoRa, then fly it under a high-altitude balloon into the stratosphere. You'll see the curve of the Earth, a black sky, and live telemetry the whole way up.

Balloon
burst in…

Up here the air is so thin the balloon has swelled to many times its launch size. Any moment now it pops.

Recovery · Parachute out

Parachute
deployed.

The canopy snaps open and slows the fall. The CubeSat keeps sending telemetry and its GNSS position the whole way down, so you can find it.

Descent

Coming
home.

Back down through the atmosphere, past the clouds, to where every mission starts.

Ground station

Plug in.
Watch it fly.

The pocket ground station is a USB LoRa receiver with its own 868 MHz antenna. Plug it into any laptop and it catches every packet from your CubeSat, then streams it straight into the Hexstar dashboard. You don't need drivers or an internet connection.

01

Plug in the ground station

USB-C into any Windows, macOS or Linux laptop. It shows up as a serial port.

02

Pull the RBF key

The CubeSat powers up and starts sending telemetry every second over LoRa.

03

Open the dashboard

See attitude, power, GNSS, environment and link quality live, and log every packet.

Every board, every part. Preliminary datasheets with specifications and full bills of materials.

Educational use only. Hexstar CubeSat kits are made for learning and educational experiments. They are not certified or intended for real spaceflight or orbital launch. High-altitude helium balloon launches are entirely at your own risk: Hexstar Universe does not guarantee that the payload will be recovered, or that data will be received throughout any mission. You are responsible for following local aviation and radio rules.
