    It is a very powerful development kit because it allows you to assemble your solution with all the elements already installed. The liion battery holder is a plus. The included sketch is in scan mode of nearby wifi networks. The revision of the board received is 3.0 and the circuit diagram can be downloaded from http://myosuploads3.banggood.com/products/20190830/20190830005003t18v3.pdf. The red LED indicates power to the board, the green network warns when the battery is charged. The battery charging

    I love these modules (i've bought so many!). They're super cheap, have 8MB of PSRAM and you can monitor the battery voltage on one of the GPIO pins. Also, flashing the ESP32 doesn't require any button pushes so it is pretty useful for development work. These are my goto modules for projects now unless i absolutely need to build tiny.

    These little powerhouses are just magnificent! So versatile, and reliable! The Li-Ion battery stays charged perfectly, so that it can be used instantly when required - like a built-in UPS! The extra RAM comes in handy for lookup tables, and for instant audio synthesis applications. (as examples) I love it!!

    Awesome product, the ability to use a wrover chip and not have to worry about it’s power supply is perfect! 18650s are becoming more and more popular anyway so a handy battery to have.
