Wemos D1 mini motor shield i2c address issue

Using Arduino Motors, Mechanics, Power and CNC

I have 2 of https://wiki.wemos.cc/products:d1_mini_shields:motor_shield from eBay. The way they arrived, I could not get an address from I2C scan. So I used this to flash them Motor Shield Reprogramming | Hackaday.io. Now I can detect them on default I2C address 0x30. The problem is that I have 2 of these in my project and by soldering the pads on the back I should be able to change the address which doesn't happen (I have tried all the combinations but it stays at 0x30 no matter what).

Motor Shield
AD1 AD0 Address

    • 0x2D
  • x 0x2E
    x - 0X2F
    x x 0x30(default)

Any ideas?

Hi,

how did you flashed it? Did you done with "Reprogramming Without Soldering" style or other?

I already did it, but nothing replied on 0x30 address..

I have made already resource on that topic. If you reflash it the backside of the panel won't change the address.
