No-name AliExpress 3-phase EV charger (EVSE) with WBR3
Differences from:
https://www.elektroda.com/rtvforum/topic4085036.html#21754359 - this one does not have a connection to the electrical meter and is 3-phase
https://www.elektroda.com/rtvforum/topic4159907.html - this one is 3-phase
These are only pictures of the inside, without any software/MCU hacking. If this is not supposed to be here, please feel free to delete it.
what does SW1 seem to do:
1,2 - i do not understand exactly, but seem to switch between 8,10,13,16A and 16,20,24,32A modes for the button
3 - most likely 1/3 phase
4 - switches C and F and also switches the limit up to 40/50A - I guess as USA do not use 3 phases
there is no way to be able to set less then 8A out of box
ARM chip is
GigaDevice
GD32F303
RET6
FX0K596
A02515

Identifies itself as GO-E31-32A in device scan
HEADER seems to be
PB11 Alternate: I2C1_SDA, USART2_RX
VCC
Header seems to be
DIO CLK GND VCC
