    I got this module from Amazon Link

    it has the CB3S Module

    flashing with the GUI app was easy

    all the pads are relatively easy accessible

    only the VCC pin is a bit obstructed by a capacitor

    and it discovered the template

    You can also just solder wires to AMS1117-3.3V pads: Diagram of AMS1117 chip connection.
    Remember to enable PowerSave 1 on this device, so you can avoid doing this fix in the future:
