Hey, community! We launched the Seeed Studio XIAO <\/a>ESP32C3<\/a> on July 7th, 2022. A new family member of Seeed Studio XIAO series<\/a>, with the rich onboard interface, thumb-sized design, and most importantly, at only a cost of $4.99. The first batch sold out in a few hours.<\/p>\n\n\n\n

Notice that the XIAO ESP32 supports a two-wire automotive interface (TWAI), which is compatible with ISO11898-1 classical frames (CAN 2.0<\/em><\/strong>).<\/p>\n\n\n\n

\"TWAI
Reference from: Two-Wire Automotive Interface (TWAI) – ESP32 – \u2014 ESP-IDF Programming Guide latest documentation (espressif.com)<\/a><\/figcaption><\/figure><\/div>\n\n\n\n

For CAN 2.0<\/strong>: XIAO ESP32C3 supports TWAI controller, so you only need one additional TWAI transceiver.<\/p>\n\n\n\n

For CAN FD<\/strong>: If you want to use CAN FD, you need an outside CAN FD controller as well as a CAN FD transceiver. <\/p>\n\n\n\n

This is great for automotive, multiplexing for use within road vehicles and other control applications. So, we are planning to combine XIAO ESP32C3 and CAN BUS<\/a>, aiming at a cost-effective and compact prototyping kit or device. It could be as a tiny CAN analyzer<\/em><\/strong>, a CAN-to-MQTT data logger<\/em><\/strong> or we could add additional onboard sensors<\/em><\/strong>, etc. Do you think it is a good idea to meet your demand? We will listen carefully and take action to respond to your passion.<\/p>\n\n\n\n

<\/p>\n\n\n\n

During the past few months, \u00a0Seeed builds the Wio-E5 CAN Development Kit together with the community.<\/a> Based on valuable suggestions from our community, we moved a few more steps towards production with updates to the design. Finally, we launched the Wio-E5 CAN Development Kit on June 2nd<\/a>.<\/p>\n\n\n\n

Now and again, we need to get your valuable input and feedback before we finalize the product design<\/strong>.<\/p>\n\n\n\n
