Seeedstudio LoRa-E5 CAN dev board goes on pre-order for $39.90

Jun 4, 2022 — by Giorgio Mendoza 516 views

Seeed Studio is offering a STM32 based LoRa CAN with support for CAN 2.0 (up to 1Mb/s) and CAN-FD (up to 5Mb/s) protocols. The company introduced the initial product proposal not so long ago and the device was well received by the community. The dev kit has been designed to be used as a vehicle monitoring device and it’s now available for pre-order at $39.90.

The development kit accommodates the STM32WLE5JCTM, which combines the ultra-low-power Semtech SX126X LoRa and an ARM Cortex-M4 processor (up to 48MHz) into a single chip. The device has a coverage of up to 10km in an open area and it’s CE/FCC certified.

The design of the LoRA-E5 CAN FD Dev board enables all the 28 pins of the LoRa E5 chip through different connectors, for example, Grove connectors, RS-485 terminal and 2×9 dual row pin headers. The dev board can be powered by USB Type-C, LiPo batteries or solar power input.
