BalenaFin: a board for fleet owners

The balenaFin is a professional carrier board for the Raspberry Pi Compute Module.
Fin Board
Parachute Image
Hardened design for field deployment use cases
Raspberry Pi based
Built around the Compute Module 3 Lite, a tried-and-true processor with a robust developer ecosystem.
Reliable Storage
On-board 8/16/32/64 GB industrial eMMC is more reliable than SD cards
Extended Power Range
6 to 24V range (5V @2.5A via HAT) with barrel jack and phoenix connector
Flexible networking
Dual-band WiFi, Bluetooth, mini PCIe for cellular modems and peripherals, and a SIM card slot
Real-time and low-power capable
Embedded 32-bit ARM M4 co-processor allows maximum power efficiency and real-time computing
Multiple interfaces to fit any use case: Raspberry Pi HAT compatible, HDMI, MIPI, I2C, SPI, UART and GPIO
Why Balena Fin?
We designed the balenaFin to reduce the friction that fleet owners face while building, deploying and scaling large fleets of connected devices. We’ve been working with our community and customers on thousands of use cases over the past few years, and it has become clear that scaling hardware is a problem.
The balenaFin is a Raspberry Pi Compute Module carrier board that can run all the software that the Raspberry Pi can run, but hardened for deployment in the field. Even better, it’s offered at an accessible price point relative to other professional boards.

Frequently asked questions

Do I have to use the balenaOS or balenaCloud, and vice versa?
No! Any recent OS distribution (2018+) for the Raspberry Pi 3 Model B should be compatible with the balenaFin. This includes Raspbian and balenaOS 2.x targeting the “balenaFin” device-type.

What do I need to get up and running?
The minimum requirements to be able to run the balenaFin are a Raspberry Pi Compute Module 3 Lite (CM3L) and a 6-24V PSU. These are included in the Fin Developer Kit, as seen here.

Can I use any Compute Module?
The balenaFin supports the Raspberry Pi Compute Module 3 lite​ (CM3L). “Lite” means that the module itself has the eMMC socket unpopulated and the traces are exposed via SODIMM-200. This is important since non-Lite versions will not work with the Fin’s on-board storage.

The balenaFin doesn’t quite work for my use case. Do you offer customizations?
We offer the possibility to depopulate the board of certain components that don’t fit for a particular use case, given a minimum order quantity. We don't currently have the ability to take custom hardware modifications or to add components. Please contact us at to learn more.

How long will the balenaFin be supported?
The availability of the balenaFin is guaranteed until January 2023.
