WBR2, WBR3, WBRU, W701-VA2-CG pinout, datasheet, flashing for Home Assistant

Don't forget to take a backup if you do continue! 🤓

I asked for flashing without desolder

Our flasher supports now WBR3: But I still think you need to access the pads on the bottom of the board, RX TX will not suffice. It's not Beken!

There is a possibility that it can be flashed via cloudcutter >>21787961 This guide is in need for an update, since it RTL8720C read/write is supported by BK7231GUIFlashTool. (pg tool can read flash if a secret combination is entered. Left click slowly on Offset 3 times and then right click on Length(Byte) 4 times, a button Read will appear on the right to Erase button. If failed, then restart tool)

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:
