ToqueCAN: Pi Toque With 2x CAN, 3 Port USB Hub and 24V>5V@5A Regulator

2x (2x2) MX3.0 connectors for CAN bus communication and power supply for up to 2 CAN bus devices.

Up to 1M CAN is supported. Both Candlelight and Klipper (in bridge mode) firmwares are supported.

Even more CAN devices are supported through the MOAR_CAN expansion connector.

3x USB-A connectors are available through the 4-port USB hub built into the ToqueCAN. The other USB port is internally connected to the MCU for CAN bus.

5V addressable RGB LED connector for controlling LEDs like Neopixels, WS2812 (RGB), SK6812 (RGBW) and similar.

Neopixel control is only supported when using Klipper (in bridge mode) firmware.

ToqueCAN supports PWM fans for cooling the Raspberry Pi (or similar SBC). 5V and 24V (or input voltage) fans are supported.

ToqueCAN has a 30mm fan cutout on the PCB. Fans up to 40mm are supported. Fan mount requires 3D-printed parts. Fan and fan mounting hardware are not included.

ToqueCAN features a buck converter for powering the Raspberry Pi (or other similar SBC), USB devices and the ToqueCAN itself from your printer's power supply. Up to 24V input voltages are supported.

Screw terminal for power input for the ToqueCAN. Up to 24V input voltages are supported.

Up to 8A is available for power draw through the CAN bus connectors.

10A fused (replaceable) for protection.
