Excellent!!!

This is a mediocre product. I tested its boost capability from 3.0V here are the results I measured with my bench power supply and an USB meter:* Vin 3.0V, Ipsu=2.1A, Vout=4.88V Iout=1.0A* Vin 3.0V, Ipsu=3.1A, Vout=4.80V Iout=1.47A* Vin 3.3V, Ipsu=3.1A, Vout=4.77V Iout=1.65AIt is visible that it is far from 5.0V, Vout drop quickly even above 1.0A load. It can withstand 3.0A for a couple of minutes (I did not test it longer), but with such a voltage drop, it is only hardly better than the Mt3608 based boards, but this is really expensive at this price level (2.5USD). If it was below 1USD, I'd call it as a good purchase,

***AS INSTR: These octal bus transceivers are designed for asynchronous two-way communication between data buses. These devices transmit data from the A bus to the B bus or from the B bus to the A bus, depending on the level at the direction-control (DIR) input. The output-enable input can be used to disable the device so that the buses are effectively isolated.

***: The -1 version of the SN74ALS645A is identical to the standard version, except that the recommended maximum IOL is increased to 48 mA. There is no -1 version of the SN54ALS645A.

***: The SN54ALS645A and SN54AS645 are characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS645A and SN74AS645 are characterized for operation from 0°C to 70°C.
