CC14: common questions

What microcontroller does the CC14 use?

The CC14 is built around the ESP32-S3-WROOM-1-N8R8, from the ESP32 family.

How big is the CC14 PCB?

The CC14 measures 129.5 × 103.5 mm, has 2 copper layers and is 1.58 mm thick.

How many components are on the CC14?

58 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the CC14 design files?

From the BadgePiratesLLC/CactusCon14 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the CC14 design in my own project?

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

Can I test firmware for the CC14 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.
