CANoolder: CAN to 3.3V interface

September 5, 2017September 1, 2017 fustiniAutomotive, CANLeave a comment

Colin O’Flynn of NewAE designed this simple CAN to 3.3V logic level interface:

CANoodler

CANoodler is a simple CAN (not CAN-FD) interface, which provides logic-level 3.3V output. It’s designed to be used with microcontrollers that have CAN blocks inside them, and in particular uses a pinout on some ChipWhisperer CW308 (UFO) Target boards.

It’s kinda nice (I think anyway) since it has these features:

LEDs for TX/RX (uses MOSFET to drive LEDs so doesn’t slow your I/O pins down).

Reverse-polarity protection on 3.3V input.

Switch for CAN termination on/off with LED feedback.

The design files are available on GitHub:

Trailer Brake Light Controller

Kevin H. Patterson designed this solution for trailer light wiring after installing a towing hitch on his vehicle:

Custom Brake Light Controller Expands your Trailer’s Capabilities

This is a power module designed to control trailer lights based on signals from your vehicle’s lighting circuits. Most vehicles have at least 4 separate circuits: Running (Tail) Lights, Brake, Left Turn, and Right Turn. Most basic trailers have a 4-wire connector with only 3 signals: Running (Tail) Lights, Left Turn, and Right Turn. The trailer does not have a separate circuit for Brake lights; applying the Brake is supposed to light up both the Left and Right Turn signals together.

The board can be purchased on Tindie:
