    Thanks. Good item. All works. The module has come with preloaded demonstration code.Some are wondering if this is really STM8S103F3 or relabeled STM8S003F3Their differences: - Flash write/erase cycles: 10 kcycle vs 100 cycles on STM8S003F3 - EEPROM: 640 byte (300 kcycle) vs 128 byte (100 kcycle) on STM8S003F3 - STM8S003F3 hasn't 96-bit Unique IDThe test is shown to the module have MCU with 640KB of EEPROM, and have 96-bit unique key at 0x004865 It can be argued with high probability that this is a STM8S103F3 MCU

***as Instruments Inc.
The ’HC257 and ’HCT257 are quad 2-input multiplexers which select four bits of data from two sources under the control of a common Select Input (S). The Output Enable input (OE\) is active LOW. When OE\ is HIGH, all of the outputs (1Y-4Y) are in the high impedance state regardless of all other input conditions.
***
Moving data from two groups of registers to four common output buses is a common use of the 257. The state of the Select input determines the particular register from which the data comes. It can also be used as a function generator.
