Poorman's cases

I solved the reversed gnd/v3vcc in a replacement oled by speading a ‘gap’ into the leads to miss the middle gnd hole and line up the gnd/3v3/xxx/22(scl)/21(sda)

Also note the pictures on most of the t-beams for sale on aliexpress are not correct in defining the header holes… see how pins 22 and 21 are wrong order and the DCDC1 is mislabeled.

Edit 8/25: The picture has been corrected on aliexpress
