ePulse Feather C6 – An ESP32-C6 development board with Adafruit Feather form factor, LiPo battery support

ThingPulse ePulse Feather C6 is a new ESP32-C6 development board with WiFi 6, BLE5, Zigbee, Thread, and Matter connectivity that follows the Adafruit Feather form factor and supports LiPo battery charging through a charger IC and a fuel gauge.

Just like its predecessor called ePulse Feather, the ePulse Feather C6 is optimized for low power consumption but replaces an ESP32-WROVER-E-N8R8 module but an ESP32-C6-MINI-1 with a 802.15.4 radio for Zigbee, Thread, and Matter, as well as 2.4 GHz WiFi 6 and Bluetooth 5.3 LE connectivity.

ePulse Feather C6 specifications:

• Wireless module – ESP32-C6-MINI-1
  • SoC – ESP32-C6H4 32-bit RISC-V microprocessor up to 160 MHz with 320KB ROM, 512KB HP SRAM, 16KB LP SRAM, 4MB flash
  • Wireless – 2.4 GHz WiFi 6 with Target Wake Time (TWT) support, Bluetooth 5.3 LE and Mesh, 802.15.4 radio with Zigbee, Thread, and Matter
  • PCB Antenna
• USB – 1x USB Type-C port for power/charging and programming
• Expansion – 12-pin + 16-pin headers with up to 17x GPIOs, 2x USB pins, 1x fuel guage pin
• Power management
  • Supply Voltage
    • 5V via USB-C port
    • 3.3 to 6V via Vin pin
  • XC6220B33 LDO
  • LiPo battery support via 2-pin JST connector
  • TP4065 charging IC and MAX17048 fuel gauge
• Power Consumption – Deep sleep: around 18uA above 3.3V or about 33uA below 3.3V
• Dimensions – PCB: 50.8 x 24.4mm; with ESP32-C6-MINI-1 and USB-C port: 57.4 x 24.4mm (Adafruit Feather and breadboard compatible)
  
• Weight – About 12 grams
• Certifications – FCC and CE

Another change compared to the previous ePulse Feather board is that it does not include an external UART chip for programming. as ESP32-C6 handles that directly through the USB-C data lines connected to pins 12 and 13. ThingPulse does not provide any software as the board can be programmed as a standard ESP32 C6 Dev Module with the ESP-IDF or Arduino IDE and most of its differentiating features are hardware-related. You’ll find the PDF schematics, STEP file, and pinout diagram on GitHub.

ThingPulse is selling the ePulse Feather C6 board for $14.95 on its online store, but they also told us CNX Software readers can get a 15% discount with the coupon code cnx-feather-c6 bring the price down to $12.70 before shipping.
