T-2Can get it now

Overview

T-2CAN is a compact dual-channel CAN communication module based on ESP32-S3-WROOM-1U (16 MB Flash, 8 MB OPI PSRAM). Features two independent MCP2515 CAN controllers (CAN 2.0B, up to 1 Mb/s), wide-range 12–24 V DC input, signal isolation design (SGND/DGND), IPEX antenna interface, QWIIC expansion, and Type-C USB. Suitable for industrial-grade CAN bus applications and IoT gateways.

FAQ

• Q. Why does my board keep failing to upload programs? A. Hold down the BOOT button and try uploading again.

• Q. Why is there no serial data output from the Uart interface? A. The project defaults to USB CDC as Uart0. Set USB CDC On Boot to Disabled in Arduino Tools, or change -DARDUINO_USB_CDC_ON_BOOT=true to false in platformio.ini.
