Optimized for Low Power Consumption
The ePulse Feather, a low-power ESP32 development board, is optimized for applications requiring low sleep current and LiPo battery support. The VIN pin accommodates voltages between 3.3V and 6V. During deep sleep, the ePulse board consumes only between 18uA (when above 3.3V) and 33uA (when below 3.3V). In comparison, most ESP32 and ESP8266 boards typically consume around 100-130uA.
This exceptionally low sleep consumption makes it ideal for applications where the device remains dormant for extended periods, awakening only when necessary to perform a task. For example, a WiFi remote control for home automation can remain in sleep mode until a user presses one of the buttons. Upon activation, the device wakes up, connects to WiFi, sends the command over MQTT, and then returns to sleep until the next button press.
Ideal Form Factor for Prototyping
The ePulse dev board is perfectly sized to fit into a breadboard, leaving one row of pins free for prototyping your circuit. Additionally, we’ve ensured that the dev board’s PCB does not obstruct the antenna of the ESP32 module. This ensures optimal signal strength for both transmission and reception.
The ESP32-C6 does not have an external UART chip for programming. The USB-C data lines are connected to the pin 12 and 13 of the ESP32-C6 and the UART chip in the ESP32-C6 takes care of programming and console output.
Powerful ESP32 Module
This board takes advantage of the ESP32-C6-Mini-1 module which breaks out many of the ESP32’s pins. It also comes with 4MB flash memory to store your firmware or a internal file system. The ESP32-C6-Mini-1 module has passed several certification programs like FCC and CE.
The ePulse development board gives you access to no less than 20 GPIO pins.
Integrated LiPo Battery Circuitry
The ePulse Feather is an ideal choice for your battery-powered projects. It employs the TP4065 chip to charge your LiPo batteries, and it comes equipped with a standard JST connector for easy connectivity. It’s important to note that the board does not include circuitry for over-discharge protection. We presume that you utilize batteries with built-in protection for this purpose.
