About the Promini cc1101 PCB

Promini cc1101 is an open source AVR/Arduino PCB design by 13, published on GitHub. It is a 2-layer board measuring 17.8 × 60 mm, with 9 components from 9 distinct parts.

Its main chip is the Arduino Pro Mini 3V3/8MHz, from the AVR/Arduino family. Other key parts include the CC1101 868MHz 11-pin. By type, the board carries 2 connectors, 2 capacitors, 2 resistors, 1 IC, 1 module and 1 transistor.

It belongs with the rf & radio and sensors designs in this gallery.

From the project

A 17.78 x 60 mm two-layer carrier (v1.5) that hard-wires an Arduino Pro Mini to the common green 11-pin CC1101 868 MHz module (19.3 x 17 mm, castellated pads). The Pro Mini sits on the top side, the CC1101 module on the bottom side at the far end, so the board is exactly as wide

The Pro Mini sits on the top side, the CC1101 module on the bottom side at the far end, so the board is exactly as wide as the Pro Mini and as long as the two modules end to end.

Promini cc1101: common questions

What microcontroller does the Promini cc1101 use?

The Promini cc1101 is built around the Arduino Pro Mini 3V3/8MHz, from the AVR/Arduino family.

How big is the Promini cc1101 PCB?

The Promini cc1101 measures 17.8 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Promini cc1101?

9 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Promini cc1101 design files?

From the 13/muhradio_pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Promini cc1101 design in my own project?

The repository has no license, so all rights stay with 13. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Promini cc1101 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.
