Introducing Esp32-C6-Bug, a compact yet powerful development board built around the latest Esp32-C6FH4 RISC-V MCU from the Esp32 family. This versatile board supports multiple wireless protocols, including Wi-Fi 6, BLE 5, Thread, and Zigbee, making it ideal for a wide range of applications. Equipped with low power consumption and battery support, the Esp32-C6-Bug is perfect for projects requiring energy efficiency and wireless connectivity.

The Esp32-C6-Bug features castellated holes for easy integration into other products and neatly fits on a breadboard for prototyping. Its integrated 32.768 kHz RTC oscillator ensures accurate timekeeping, while power consumption as low as 20uA in sleep mode maximizes battery life. Programming can be done using both the Arduino framework and Esp-IDF, with examples readily available for quick start.

Esp32-C6-Bug front and back

To extend the capabilities of the Esp32-C6-Bug, we introduce the Esp32-Bug-Eth companion board. This add-on board features Ethernet and PoE support, utilizing the widely-supported W5500 Ethernet chip and DP1435-5V isolated PoE module. Additionally, it includes a Stemma QT/QWIIC compatible connector for seamless integration with various sensors.

Manufacturing Plan

We have a long-term manufacturing partner ready to begin production promptly after the funding process. They will inspect boards to ensure quality assembly, and package the products into ESD bags together with the pin headers for quick and convenient processing.

Fulfillment & Logistics

After our production run is complete, we will box everything up and send it along to Crowd Supply’s fulfillment partner, Mouser Electronics, who will handle worldwide distribution to backers. Learn more about Crowd Supply’s fulfillment service under Ordering, Paying, and Shipping in their guide.

Risks & Challenges

Our manufacturing and packaging pipeline has been thoroughly tested, and we chose all components to be common and easy to source. The most non-standard part is Esp32-C6FH4, which is well stocked on Mouser. In the event that any parts become out of stock, we have a very reliable parts supplier in China who available for alternate parts sourcing.

In the Press

Hackster News

"With 19 GPIO pins exposed, surface-mount support, and radios for Wi-Fi 6, BLE, and Zigbee/Threads, this board is ready for the IoT."

CNX Software

"We’ve already covered a range of ESP32-C6 boards, but none supporting Ethernet and PoE so far, and the ESP32-C6-Bug board brings that to the table thanks to the Esp32-Bug-Eth shield with a W5500 Ethernet chip, an RJ45 jack and a PoE power module."
