Shipment dispatched after 2 days. The package arrived 12 days after ordering. Carrier: Aliexpress Standard Shipping The module was not able to be calibrated at 2.5V output without modification. The potentiometer and 5k1 resistor only got the reference voltage to 0.86V instead of the 0.833V needed for a 2.5V output. Cutting the trace between the TL431 and the potentiometer and replacing the trace with a resistor (1k-10k) fixes the offset problem.
