Now only two layers!
Specs:
- ESP32-S3-WROOM-1
- USB-C
- In-built E-Stop button and AUX E-Stop port (3.5mm TRS jack)
- No USB-UART, uses built-in USB on ESP32-S3
- 3.3v regulator
- More compact than v1
- Footprint 40mm x 56mm
Important ordering information:
- PCB Thickness: 1.0mm
- 2 Layers
- Impedence Controlled for JLCPCB's 1.0mm stackup
- Edge Rails in source files are not attached, and are not included in JLC gerbers
- Standard PCBA only (As of writing, Economy PCBA is unsupported for the ESP32-S3 modules due to solder reflow curve requirements)
JLCPCB may contact you about a couple of things:
- WS2812B-Minis may incur an extra component baking fee (~$8-10)
- Rotations of WS2812B-Mini and Antenna. Ensure that they match these examples:
Redlines (v2.0) (Solved in v2.1+):
- R1 (high side pullup for RF TX level-shifting) was causing unwanted RF signals when IO1 was Hi-Z/Input Enabled.
- EN pin missing debounce capacitor.
Redlines (v2.1):
- To be discovered.
Redlines (v2.2):
- To be discovered.

Questions
How big is the Core v2-rounded PCB?
It measures 40 × 56 mm and has 2 copper layers, 0.99 mm thick.
What parts does the Core v2-rounded use?
91 parts, built around the DL-TX1-433M, ESP32-S3-WROOM-1-N8, BSS138 and PJ-3200. 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.
Where can I download the Core v2-rounded KiCad files?
From the OpenShock/Hardware repository on GitHub, at the commit this page was made from: the board is Core v2/Core v2-rounded.kicad_pcb and its schematic Core v2/Core v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Core v2-rounded design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
