About the F91 main board nf

F91 main board nf is an open source TI MSP430/CC PCB design by jacobl423, published on GitHub under the MIT license. It is a 2-layer board measuring 24.4 × 24.4 mm, with 65 components from 43 distinct parts.

Its main chip is the CC2640(long pads), from the TI MSP430/CC family. Other key parts include the BT_Antenna and 5050660622. By type, the board carries 18 capacitors, 6 resistors, 5 inductors, 3 connectors, 2 ICs and 2 crystals.

It belongs with the displays & leds designs in this gallery.

From the project

updated f91 kepler project

Found here are the PCB files as well as 3D parts that were made to accommodate this project.

My first design for the board used FPC connectors for the display (4 pin) as well as one for programming/debugging (11 pin). This was later changed to use the Molex board to board connector for the display and small connection points across the PCB for programming/debugging. These changes were made to save room and make it easier to not have to solder and unsolder an FPC connector for programming/debugging. The connection points are hard to see in the real images, but are visible in the render seen…

F91 main board nf: common questions

What microcontroller does the F91 main board nf use?

The F91 main board nf is built around the CC2640(long pads), from the TI MSP430/CC family.

How big is the F91 main board nf?

The F91 main board nf measures 24.4 × 24.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the F91 main board nf?

65 components, from 43 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 F91 main board nf design files?

From the jacobl423/F91_Jepler repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the F91 main board nf design in my own project?

Yes, under the terms of its MIT license, which jacobl423 chose for the repository.

Can I test firmware for the F91 main board nf without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug TI MSP430/CC firmware against it before you order a PCB.
