Adafruit ESP32-C6 Feather - STEMMA QT

The ESP32-C6 is a groundbreaking Wi-Fi 6 SoC from Espressif, integrating 2.4 GHz Wi-Fi 6, Bluetooth 5 (LE), and the 802.15.4 protocol. This versatile hardware enhances the C3 series with Zigbee/802.15.4 at 2.4GHz, making it ideal for Matter development.

This Feather board swaps the ESP32-S2 for a C6, ensuring ample GPIO, LiPoly charging and monitoring with the MAX17048, and a NeoPixel. The I2C Stemma QT port, along with a second low-quiescent LDO, ensures ultra-low power usage, down to 17uA in deep sleep.

Note that the ESP32-C6 does not feature native USB capabilities. While it includes a USB Serial core for debugging, file transfer must occur via WiFi, Bluetooth, or WebSerial when using CircuitPython. Its GPIO count offers compatibility with existing FeatherWings despite some overlap in pin usage.
