    These little boards loosen your hands and I think they should be in every amateur electronics. Price that does not even need discussion.
    Αυτά τα μικρά πλακετακια σου λύνουν τα χέρια και θεωρώ πως πρέπει να υπάρχουν σε κάθε ερασιτέχνη ηλεκτρονικό. Τιμή που δεν χρειάζεται καν συζήτηση.

      Q: hello can I input 12V with a 5v output ?
      A:
      Look on the board and you'll see a toroidal inductor. Remove the copper wire from that and your tiny cock will fit through the centre.

      Q: if i run a 3.7v lipo battery into this product, will i be able to power the necessary 8-25v needed for the 24vGeekcreit® TDA7492P 50W+50W Wireless bluetooth 4.0 Audio Digital Amplifier Board ??
      A:
      first of all the TDA7492P is not supposed to be 50W+50W but 25W + 25W continuous output power at THD = 10% with VCC = 20 V and RL = 8 ohms, max current 4.2A, minimum TDA7292P voltage is 8V, DC-DC converter cannot provide enought power from 3.7V you will have to serialize multiple 3.7V, look at the voltage and amps sheet in the decsription.

      Q: I want to use this to create a regulated 3.3v supply for an ESP8266, the source is a 3.7v lipo, thus the input voltage will vary from 3 to 4.2v, but I need the constant 3.3v output. This means that the input voltage will sometimes be higher than the required output voltage. Possible or not?
      A:
      No this is only for boosting ! You need a regulator which features as buck and boost at the same time..
