About the Cc1101-morse PCB

Cc1101-morse is an open source ESP32 PCB design by vinicius-cardoso, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 40 × 60 mm, with 11 components from 9 distinct parts.

Its main chip is the ESP32-C3-SuperMini, from the ESP32 family. By type, the board carries 4 test points, 2 connectors, 2 capacitors, 1 IC, 1 buzzer and 1 switch.

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

The KiCad project lives in cc1101-morse/, alongside libraries/.

libraries/ holds the ESP32-C3 Supermini symbol and footprint, which the stock KiCad libraries do not carry. Nothing else is needed from a custom library: the CC1101 is a socketed module represented by a generic Conn02x04OddEven`, and everything else is a stock KiCad part.

Two things from docs/hardware.md that are easy to get wrong and expensive to discover late:

The KiCad project lives in the vinicius-cardoso/cc1101-morse repository on GitHub; these links point at the commit this page was built from.

Cc1101-morse: common questions

What microcontroller does the Cc1101-morse use?

The Cc1101-morse is built around the ESP32-C3-SuperMini, from the ESP32 family.

How big is the Cc1101-morse PCB?

The Cc1101-morse measures 40 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cc1101-morse?

11 components, from 9 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 Cc1101-morse design files?

From the vinicius-cardoso/cc1101-morse repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Cc1101-morse design in my own project?

Yes, under the terms of its GPL-3.0 license, which vinicius-cardoso chose for the repository.

Can I test firmware for the Cc1101-morse without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
