Produto veio bem embalado e chegou conforme tempo previsto.
Nice price for 5 piece of 3.3V voltage regulators. Suitable for breadboard testing and low voltage projects. very little module.
Efficace et pratique
I recommend it to everyone
Superb little device allows a completely wireless (with no PSU) LED array to be controlled by a 3v MCU (inside the ESP8266) in this particular instance via WiFi by regulating the battery voltage to a safe level for the MCU...
I have several Arduino Pro Mini s that are 5 volts only. I needed a 3.3 V source to run a nRF24L01 2.4 MHz communication link. These little devices plug in nicely to bread board and provide the power I need. And they came relatively quickly ~10 days to US
صغير جداً، جيد.
