Supporting transmission rates up to 1Mbit/s, it features enhanced electromagnetic compatibility and electrostatic discharge protection. Compatible with 3V to 5V microcontrollers, it ensures seamless integration with Arduino and ESP32 platforms. The transceiver enters a low power mode where it becomes invisible on the bus, optimizing energy efficiency. Sold as a 2-piece set, it’s ideal for building or upgrading CAN network nodes. ## Description Description:CJMCU-1051 is a high-speed CAN transceiver and the interface between the CAN controller and the physical bus, which provides differential transmit and receive functions for the CAN controller.The transceiver is designed for the automotive industry's high-speed CAN applications, Transmission rate is up to 1Mbit / s.Feature:The TJA1051 is an upgraded version of the high-speed CAN transceiver TJA1050 with improved electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance, with the following features:1. The transceiver is not visible on the bus when the power is off or in low power mode;2. TJA1051T/3 and TJA1051TK/3 I/O port can be directly connected with the 3V ~ 5V microcontroller interface.These features make TJA1051 become the best choice for high-speed CAN network node , TJA1051 does not support bus wake standby mode.Package included:2x CAN Transceiver(If the number of products received is incorrect, please contact us . we will refund or give you a replacemeOutput DC: 2.5-35v.nt) Review: This CAN transceiver needs a CAN controller to work. esp32 has the controller built in. Also I only got it to work with 5v. Tested with ESP32CAN.h and the library examples that were included. Review: This could just be my bad luck/inexperience, but I could not for the life of me get these transceivers to work. I've double-checked my wiring, tried a different arduino DUE, and probed every pin, but no matter what I do the basic ping-pong CAN test won't work. Apparently I should've read more carefully online β€” I've seen in at least two places that this type of transceiver model is unreliable. I'm going to try out the SN65HVD230 transceiver instead, hopefully that ends up working. ## Features - CJMCU-1051 is a high-speed CAN transceiver and the interface between the CAN controller and the physical bus, which provides differential transmit and receive functions for the CAN controller. - The transceiver is designed for the automotive industry's high-speed CAN applications, Transmission rate is up to 1Mbit / s. - The transceiver is not visible on the bus when the power is off or in low power mode; - Package included: 2x CAN Transceiver(If the number of products received is incorrect, please contact us . we will refund or give you a replaceme) - We highly appreciate all customers opinions to improve the selling, also if anything you unsatisfied, please contact us for probable best solution. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YHYQ7C9 | | Are Batteries Included | No | | Brand | Comimark | | Customer Reviews | 4.2 4.2 out of 5 stars (12) | | Date First Available | 11 January 2020 | | Hardware Platform | Arduino | | Item Weight | 18 g | | Item model number | LY546 | | Manufacturer | Comimark | | Package Dimensions | 12.29 x 7.8 x 0.71 cm; 18 g | ## Images ![Comimark 2Pcs CJMCU-1051 TJA1051 High-Speed Low-Power CAN Transceiver for Arduino - Image 1](https://m.media-amazon.com/images/I/61B0UBpXfIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***S on 26 September 2022* This CAN transceiver needs a CAN controller to work. esp32 has the controller built in.
