New arduino project. Wireless weather mini station with electronic ink display 2.9 inches (GDEH029A1 OR GDEM029T94), very low power consumption,compact size, housing with magnets. The device can use si7020 / 21, sht20 / 21, HTU20/21D or BME280 sensors. Use the MINEW MS50SFA RF module with nRF52832 chips, or the EBYTE E73 module with nRF52840 and nRF52833 chips.
I have the model with one battery slot. I received the small plastic part to flash. But there are no pictures describing where to plug into the device.
