Overview
Canpmod is an open-source printed circuit board by disdi, from the disdi/canpmod repository on GitHub, published under the MIT licence. It is a 2-layer board of 37.6 × 18.5 mm with 12 parts on 17 nets, routed with 41 tracks and 1 via.
It is built around the SN65HVD230D. Its parts include 5 resistors, 3 capacitors, 2 connectors and 1 IC.

README.mdCAN PMOD
CAN PMOD is a 3.3 V SN65HVD230 CAN transceiver module, based on the Waveshare SN65HVD230 CAN board. The host must provide the CAN protocol controller.
The project is KiCad 9.0.8. Open kicad/canpmod.kicad_pro. The two-layer, 1.6 mm board has 12 components and keeps its original outline and component placement.
This revision corrects the PMOD footprint's physical numbering, reroutes the affected nets, adds local connector footprints, and refreshes silkscreen and library symbols. ERC reports 0 errors and 0 warnings. DRC with schematic parity reports 0 violations and 0 unconnected items.
The photographs above show the original board. They remain in img/ as
historical images.
PMOD connections
J2 is the right-angle male PMOD header. Viewed from the PCB top with its plug pointing left, pins 1–6 run top to bottom in the inboard row; pins 7–12 run top to bottom in the outboard row. Pin 1 is square and marked on silkscreen.
| PMOD pin | Signal | Function |
|---|---|---|
| 1 | NC | Unconnected |
| 2 | NC | Unconnected |
| 3 | NC | Unconnected |
| 4 | CAN RX | CAN receive (input to host) |
| 5 | GND | Ground |
| 6 | 3.3 V | Supply from host |
| 7 | NC | Unconnected |
| 8 | NC | Unconnected |
| 9 | NC | Unconnected |
| 10 | CAN TX | CAN transmit (output from host) |
| 11 | GND | Ground |
| 12 | 3.3 V | Supply from host |
J1 is the 5.08 mm-pitch CAN terminal: pin 1 CAN_L, pin 2 CAN_H. JP1 enables the 120 Ω termination when a shunt is fitted.
R1 is the 4.7 kΩ slope-control resistor. R2 pulls TX high. C1 is the 100 nF supply bypass. R3/C2 and R4/C3 are 100 Ω / 560 pF series RC branches from each bus line to ground.

J2 needs a manufactured right-angle 2×6 header matched to the footprint. Exact connector MPNs, passive ratings, assembler acceptance, and bench validation remain open. Clean ERC/DRC is not fabrication approval.

Questions
How big is the Canpmod PCB?
It measures 37.6 × 18.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Canpmod use?
12 parts, built around the SN65HVD230D. 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 Canpmod KiCad files?
From the disdi/canpmod repository on GitHub, at the commit this page was made from: the board is kicad/canpmod.kicad_pcb and its schematic kicad/canpmod.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Canpmod design in my own project?
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).
