Product main upgrade function attributes:
1: Change the original ESP32 module to a single ESP32 chip.
2: The charging IC is changed from the original TP5400 to TP4054.
3: The original MICR seat is changed to TYPE-C.
4: The original normal power supply mode is changed to the button sleep wake-up mode (or the customer does the timing wake-up by himself).
5: The size of the board is 45MM smaller than the previous length, and the width is increased by 2.54MM
Added part:
1: Added sleep button wake-up function (IO35)
2: Added the function of testing soil salinity (CD4060BM+TL034IDR)
3: Increase the intensity test of light (BH1750FVI)
4: Reserved external device expansion (single bus serial port IIC—-21~22)
Advantage:
The battery life is much longer than before. In the case of testing moisture, you can test the soil salt and photosynthetic absorption, reasonable fertilization and proper sunshine.

    Excellent android box

    I bought one for us. And to be honest I was VERY SCEPTICAL. But once installed the sky is the limit on what you can do. Our kids are grown with their own children and even the grandchildren know how to operate it and love the video options. So we decided to get them their own and not to brag but mom and dads gift were the bomb. Even the grandchildren were excited

    A+ If you use the right cup!

    After having it for a few days I love it! I tried it with different cups and mugs and you’ll want to use the a mug with a flat base to really spread the heat. I pre heat my mug while my coffee brews and it will stay hot as long as you’d like. I found the default high heat setting worked best for me. It’s not to expensive and makes a great gift. I got mine in black and it looks great on my desk at work.

    Yes, it works!

    This thing really works. If you are reading a review that says it doesn’t then they r either not using it correctly or using the wrong product. I did not get paid to use this product or my personal opinion like others. I didn’t want to spend all the extra money on a fancy brand name with the same results. My pics will speak for themselves.
