This is a Feather Wing for ESP32 Feathers that contain a CAN tranceiver and RJ45 connectors that allow connecting an ESP32 Feather to a LCC network. The CAN is set up to use pin 11 for CAN_TX and pin 12 for CAN_RX.
Subdirectories:
- firmware Simple node, without the display, 4Meg partition table, stores node DB on Flash under SPIFFS
- firmware-display Complex node, with display, 8Meg partition table, stores node DB on uSD card (assumes Adafruit 3.5" TFT w/Touch Screen V2.0, which includes a uSD card slot).
- DisplayCase FreeCAD code for a case for the version with display.
The firmware compiles with Espressif esp-idf (at least V 5.0) and uses Mike Dunston's OpenMRNIDF library.
I am using KiCAD 6.0.11 on a Raspberry Pi 5 running Debian 12. Also I am using FreeCAD .21.2 (aarch64 Appimage).
Parts
6Questions
How big is the FeatherLCCCAN PCB?
It measures 96.5 × 22.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FeatherLCCCAN use?
6 parts, built around the RJ45. 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 FeatherLCCCAN KiCad files?
From the RobertPHeller/FeatherLCCCAN repository on GitHub, at the commit this page was made from: the board is FeatherLCCCAN.kicad_pcb and its schematic FeatherLCCCAN.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FeatherLCCCAN design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
