For a long while now I was always looking for a development board that would help me to create battery-driven IoT projects. Since I couldn’t find it we decided to design one and sell it with ThingPulse. It only consumes between 25-35uA and accepts a wide range of input voltage (3.3 – 12V).
I’m really excited that we finally have this board ready for you guys! It is at the same time very powerful and energy-efficient. By using the ESP32-WROVER-B module the board has both 8MB of flash and 8MB of PSRAM.
But we didn’t want to cut down on convenience just to achieve good power efficiency. The on-board CP2104 UART is only powered when the device is powered through the USB port. When the device is powered through the VIN port the UART is not consuming energy.
The ePulse development board is also a good fit for you in other aspects: you can put it on your regular bread-board and still have one row of pins on each side of the ePulse.
We are taking pre-orders now in our ThingPulse shop and during the pre-order phase, we offer you an attractive 25% discount. Shipping should start around February 15, 2020. Order your ePulse now!
