CANBed Drives RP2040s Into Embedded CAN Bus Functions

The Raspberry Pi RP2040 microcontroller integrates into automotive functions with the newest board from Seeed Studio. The new CANBed RP2040 interfaces to a automobile’s CAN bus and an OBD-II port.

In case you are new to CAN, take a look at this nice CAN Bus primer from Seeed Studio.

CANBed RP2040 measures 56 x 41 millimeters. The board comprises the RP2040 microcontroller, an MCP2515 CAN controller, an MCP2551 CAN receiver, a switch-mode energy provide, and an array of I/O connector ports.

SeeedStudio included a two-megabyte flash chip to assist the RP2040 with 264 kilobytes of RAM and clocks operating as much as 133 MHz. As well as, CANBed makes I2C, SPI, UART, eight GPIO, and three analog inputs out there for interfacing to different {hardware}.

Every set of IO has pinout choices. For instance, I2C makes use of Seeed Studio’s Grove Connector system, enabling connections to an unlimited ecosystem of sensors and add-ons. Additionally, whereas CAN is distinguished sufficient to be within the product’s identify, CANBed can interface to OBD-II indicators by means of a 9-Pin sub-D connector.

With the twin CAN interface ICs, the event package helps information charges as much as 1 Mb/s and CAN V2.0B. The {hardware} additionally helps CANopen, which runs on high of the CAN Bus information hyperlink layer.

The onboard energy provide operates with enter voltages of 9-28 volts. This vary means CANBed targets 12 volt automotive functions. The switching provide bucks down to three.3 volts and may provide as much as 1 amp for the board and exterior {hardware}.

In case you are involved in CANBed however favor an 8-bit microcontroller, Seeed Studio has you coated with the CANBed ATmega32U4. It has the identical processor discovered on the Arduino Leonardo board.

The RP2040-based growth package begins at $15.90. SeeedStudio estimates shipments will start on December twenty fourth, 2021. You may pre-order on the CANBus RP2040 product web page.
