Flowcontrol old: common questions

What microcontroller does the Flowcontrol old use?

The Flowcontrol old is built around the ATmega328-P, from the AVR/Arduino family.

How big is the Flowcontrol old PCB?

The Flowcontrol old measures 152.7 × 138.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Flowcontrol old?

29 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Flowcontrol old design files?

From the bl433/flow-control repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Flowcontrol old design in my own project?

Yes, under the terms of its MIT license, which bl433 chose for the repository.

Can I test firmware for the Flowcontrol old without the hardware?

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