About the TinyFISH PCB

TinyFISH is an open source STM32 PCB design by fishpepper, published on GitHub under the CERN-OHL-1.2 license. It is a 2-layer board measuring 20 × 20 mm, with 88 components from 53 distinct parts.

Its main chip is the STM32F303CCTx, from the STM32 family. Other key parts include the CC2510, MPU-6000, LP2985AIM5-3.0/NOPB, M25P16-VME and MICRO_USB_B. By type, the board carries 30 capacitors, 13 resistors, 7 ICs, 4 LEDs, 3 inductors and 2 crystals.

It belongs with the robotics & motion and sensors designs in this gallery.

From the project

openhardware f3 flight controller with an integraded uSKY receiver

My approach to build a small and lightweight flight controller.

See http://fishpepper.de/projects/tinyFISH for more details.

This thing is TINY! The outer dimensions are 20x20mm with a 16mm hole-to-hole spacing. It runs betaflight and includes a FrSky compatible RX, a current- and voltage-sensor, a blackbox logger, and it is open hardware -- go and build one yourself!

TinyFISH: common questions

What microcontroller does the TinyFISH use?

The TinyFISH is built around the STM32F303CCTx, from the STM32 family.

How big is the TinyFISH PCB?

The TinyFISH measures 20 × 20 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TinyFISH?

88 components, from 53 distinct parts. The full bill of materials is listed on this page.

Where can I download the TinyFISH design files?

From the fishpepper/tinyFISH repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the TinyFISH design in my own project?

Yes, under the terms of its CERN-OHL-1.2 license, which fishpepper chose for the repository.

Can I test firmware for the TinyFISH 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.
