Custom Sub-GHz Transceiver Gateway
CoralWave is an open-source printed circuit board by mineiwik, from the mineiwik/CoralWave repository on GitHub, published under the MIT licence. It is a 2-layer board of 54.1 × 21.9 mm with 45 parts on 39 nets, routed with 398 tracks and 69 vias.
It is built around the CC1101RGP, ESP32-C3-WROOM-02-N4 and TLV62568DBVR-TP, with the CPDQ5V0-HF, B5819W-TP and NX3225GA-26MHZ-TI among its other parts. Its parts include 22 capacitors, 8 resistors, 5 inductors, 4 diodes and 3 ICs. It belongs with the radio and wireless boards and the ESP32 and RISC-V boards of this library.
This repository contains the hardware design files for an RF transceiver system built using an ESP32-C3 module and a CC1101 RF chip. The communication between the ESP32-C3 and CC1101 is established through the Serial Peripheral Interface (SPI) protocol. The design is created using KiCad 7.

The project aims to create a versatile RF communication system by integrating the ESP32-C3 module and the CC1101 RF chip. The ESP32-C3 serves as the main controller, handling data processing and interfacing with external devices, while the CC1101 handles the RF communication with other compatible devices. This design allows for bi-directional communication over a designated RF frequency band, making it suitable for various applications such as replacing remote controls.
Note: The design around the CC1101 chip is tuned for the 315/433 MHz ISM/SRD frequency bands. (See the documentation of the CC1101 chip for more information.)
Follow these steps to open the hardware design using KiCad 7:
Clone this repository to your local machine using the following command:
git clone https://github.com/mineiwik/CoralWave.gitLaunch KiCad 7.
Open the KiCad project by navigating to the project directory and locating the .kicad_pro file. This file stores the project information.
Once the project is open, you can access the schematic and PCB layout files by clicking on the respective buttons in the KiCad project manager.
Adjust the design and/or export the gerbel files for PCB production

It measures 54.1 × 21.9 mm and has 2 copper layers, 1.6 mm thick.
45 parts, built around the CC1101RGP, ESP32-C3-WROOM-02-N4, TLV62568DBVR-TP and CPDQ5V0-HF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the mineiwik/CoralWave repository on GitHub, at the commit this page was made from: the board is CoralWave.kicad_pcb and its schematic CoralWave.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
