LE50 (STM) doesn't provide this protection : adding a 1N4148 in serial with the power supply of the module is recommanded if polarity reversal can happen. Compatible too with non low drop LM78L05M (therefore minimum supply voltage becomes 7V instead of 5.5V). (6) 20MHz oscillator, IQXO-57 package (5mm x 7mm) (7) 1% resistor, to get a good precision of the voltmeter function
