My load is a bit out of calibration (around 10% error in current), and I was checking the schematic to find where I could fix it, and found a difference to my board: R27 in mine is 1K (102 in the silk screen), just bottom left of pin 1 of the opamp IC3.
Can you confirm if it's a schematic error? I went around the opamp checking other values and coudn't find any other difference.
Thanks (and already have a couple of stm8 in the mail)

Mine is a 1k resistor (1001, with 102 silk).

Also I noticed that the programmer jumper pin numbering is backwards. pin 1 is ground 2 is reset etc.
