I received the module CD 028 today and was very disappointed. It turned out that the FM receiver operates in mono mode, although the screen says stereo. After checking the circuit, it turned out that the RDA5807M receiver, having a stereo output of the left and right channels (pins 9 and 10), then has two serial chains of a capacitor and a resistor. further The resistors are connected together and go as a mono channel to the Allwinner F1c100s processor.
Thank you. It has it's own voltage regulator, thus it can handle some variations on the power supply. 12V i think, easy to get and good enough for the item.
Dupa ceva timp de utilizare va pot spune ca trebuie sa va asteptati sa fiti extrem de frustrati de raza extrem de redusa de acoperire a telecomenzii. A mea si-a dat deja obstescul sfarsit... Din fericire am gasit o telecomanda compatibila din aia cu baterie 2032 de la un mp3-player auto, functiile nu sunt pe inscriptiile corespunzatoare dar sunt toate acolo, trebuiesc doar refacute inscriptiile la butoane, si raza de acoperire e mult, foarte mult peste cea de la telecomanda originala. After some time of usage i can honestly say that you need to expect to get extremely frustrated due to the very narrow field of coverage of the remote control. Mine has already suffered an involuntary death due to that very reason. Luckily i found another working remote from some auto mp3 player, it has all the needed commands and way better coverage!
Am aratat in prezentare, semnalul pe iesire are o amplitudine maxima de cam 400mVrms ( masurati ). Daca trebui sa nu preamplificare depinde de sensibilitatea sistemului la care este conectat, si asta nu o pot lamuri eu ci se gaseste in specificatiile tehnice ale sistemului respectiv.

Did you sort this mate? also bluetooth is labelled as BULETOOTH and time setting options are wrong, wonder if theres a firmware update for this
Amigo ela muda a música na plaquinha escutando via bluetooth?
Is this board available?
what about audio settings like EQ. or bass / treble? or other settings?
What is the voltage used in this project, Or rather, what voltage should be used to run all applications?
Nice review 😉
Thank you.

Tenga su merecido like buen hombre 👍

are nevoie de amplificare la semnalul de iesire? se poate lega direct pe intrarea de la sistem 2.1 de exemplu?
