About the S3zero cc1101 PCB

S3zero cc1101 is an open source ESP32 PCB design by 13, published on GitHub. It is a 2-layer board measuring 44.8 × 32 mm, with 5 components from 5 distinct parts.

Its main chip is the ESP32-S3-Zero, from the ESP32 family. Other key parts include the CC1101 868MHz 11-pin. By type, the board carries 2 ICs, 2 capacitors and 1 inductor.

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

From the project

A 44.8 x 31 mm two-layer carrier that wires a Waveshare ESP32-S3-Zero to the 11-pin CC1101 868 MHz module exactly as the muhradio receiver firmware expects (receiver/platformio.ini, env esp32-s3-zero-cc1101 and esp32-s3-zero-bresser). Both modules sit on the top side; the S3-Zero

A 44.8 x 31 mm two-layer carrier that wires a Waveshare ESP32-S3-Zero to the 11-pin CC1101 868 MHz module exactly as the muhradio receiver firmware expects (receiver/platformio.ini, env esp32-s3-zero-cc1101 and esp32-s3-zero-bresser). Both modules sit on the top side; the S3-Zero's USB-C powers everything.

1. Solder the CC1101 module onto its castellation pads (top side, right). 2. Solder the ESP32-S3-Zero onto its 18 pads, either flat via its castellations (the pads have a ledge outside the S3-Zero edge for the fillet) or on 2.54 mm header pins. 3. FB1 (ferrite bead), C1 10 uF and C2 100 nF…

S3zero cc1101: common questions

What microcontroller does the S3zero cc1101 use?

The S3zero cc1101 is built around the ESP32-S3-Zero, from the ESP32 family.

How big is the S3zero cc1101 PCB?

The S3zero cc1101 measures 44.8 × 32 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the S3zero cc1101?

5 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the S3zero 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 S3zero 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 S3zero cc1101 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.
