$4.9 CAN bus module features GD32E103 Cortex-M4 microcontroller

CAN Bus Grove module GD32E103

Seeed Studio has introduced a new CAN Bus Grove module based on 120 MHz Gigadevice GD32E103 Arm Cortex-M4+ microcontroller with support for CAN FD at up to 5Mbps and controlled by AT command over a serial interface. The new module appears to be a drop-in replacement for the company’s $19.90 Serial CAN-BUS Grove module based on Microchip MCP2551 and MCP2515, and the main benefit of the new GD32E103 module is that it is much more cost-effective going for only $4.90 including shipping. GD32E103 CAN BUS Grove module specifications: MCU – Gigadevice GD32E103 Arm Cortex-M4F microcontroller @ up to 120 MHz with 64KB to 128KB flash, 20KB to 32KB SRAM CAN Bus – 2-pin terminal block with CAN FD up to 5 Mbps Host connection – 4-pin Grove connector with UART up to 115,200 bps (default 9,600 bps) Misc – Tx and Rx LEDs Operating voltage – 3.3V Dimensions – 40 […]

CANDuino v3 – A Microchip ATmega168PA board with CAN bus, Arduino Nano form factor

CANDuino v3

CANduino v3 is the third revision of MassiveButDynamic’s CAN bus board with Arduino Nano form factor based on Microchip ATmega168PA 8-bit AVR microcontroller, Microchip MCP2515 CAN controller with an SPI interface, and Microchip MCP2551 CAN transceiver suitable for 12V and 24V systems. The CANDuino v3 board is now slightly narrower in order to give access to two rows on each side when installed on a breadboard, comes with a USB Type-C port to reduce the number of cables needed, and the CAN bus function can be deactivated via a jumper in order to use the CANduino as a normal Arduino Nano. CANDuino v3 specifications: MCU – Microchip ATmega168PA 8-bit AVR microcontroller @ up to 16 MHz with 16KB flash, 512 bytes EEPROM, 1 KB SRAM CAN Bus CAN L/H header and CAN bus termination Microchip MCP2515 CAN controller connected to the AVR microcontroller over SPI. Supports CAN V2.0B at 1 […]

can2040 project adds software CAN bus to Raspberry Pi RP2040 microcontroller

Raspberry Pi RP2040 can2040 software CAN Bus

The can2040 project is a software CAN bus implementation for the Raspberry Pi RP2040 microcontroller that leverages programmable I/Os (PIO) to achieve reading and writing CAN 2.0B data frames at rates up to 1Mbit per second. Kevin O’Connor, the developer of the project, further explains the implementation uses only one of the two RP2040 PIO hardware blocks, so it is possible for a single Raspberry Pi RP2040 chip to have two separate CAN bus interfaces. Some processing also happens on one of the Arm Cortex-M0+ cores of the microcontroller with the processing time dependent on the amount of bus traffic, and a fully saturated CAN bus at the fastest supported rate of 1Mbit/s may use up to around 30% of that core when clocked at 125MHz, so that should still leave plenty of room for other tasks that may run on the system. I could not find any information about […]
