About the IRIS PCB

IRIS is an open source STM32 PCB design by codinga593, published on GitHub. It is a 6-layer board measuring 80 × 80 mm, with 129 components from 48 distinct parts.

Its main chip is the STM32H753ZIT6, from the STM32 family. Other key parts include the W25Q128JVFIQ, 114993390, A121-001-T&R, AMS1117-3.3 and BNO085. By type, the board carries 55 capacitors, 32 resistors, 15 connectors, 13 ICs, 4 inductors and 3 transistors.

From the project

A next generation model rocket focused on a precise propulsive landing on a tower.

IRIS is a high powered model rocket focused on a precise propulsive landing on a custom tower, similar to SpaceX's Falcon 9. It will fly on a H45 motor to approximately 700m, guiding itself to a waypoint in the air using aerodynamic fin control. It will then begin a controlled descent where fins attempt to maintain x and y position. A landing motor (F15) then ignites to kill velocity, as thrust vectoring helps guide it to the tower where it will be caught by two motorised arms.

IRIS: common questions

What microcontroller does the IRIS use?

The IRIS is built around the STM32H753ZIT6, from the STM32 family.

How big is the IRIS PCB?

The IRIS measures 80 × 80 mm, has 6 copper layers and is 1.599978 mm thick.

How many components are on the IRIS?

129 components, from 48 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the IRIS design files?

From the codinga593/IRIS repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the IRIS design in my own project?

The repository has no license, so all rights stay with codinga593. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the IRIS without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
