RRD-305 303 Bluetooth 5.0 stereo headset voice calls DIY Bluetooth stereo wireless audio module 2024 - Come, works. For three hours, I figured out how to turn it on. It turns out you need to close for 5 seconds. Pin Power and Power EN (third contact from below). Dibils who ordered this module do not properly connect the output signal and also happy with what class transparent sound they have there. Are you even jerks? To get a good sound from this module, you need to put a differential amplifier with bipolar power on the operating amplifier after the output from the module. On the module there are no outputs: left, right, Earth. There are two anti-phase signals in each channel. And when you think you 've connected one anti-phase (Inverter) signal of one of the channels, like the total minus for the headphones, you have a steropanoram narrowing to no (or when both inverter outputs you connected to the general on the headphones). Here are the measurements of this module (only one channel). In principle, yes, the characteristics are not bad (except for the head of the frequency response after 15 kHz, and this is without load).

RRD-305 303 Bluetooth 5.0 stereo headset voice calls DIY Bluetooth stereo wireless audio module 2024 - Come, works. For three hours, I figured out how to turn it on. It turns out you need to close for 5 seconds. Pin Power and Power EN (third contact from below). Dibils who ordered this module do not properly connect the output signal and also happy with what class transparent sound they have there. Are you even jerks? To get a good sound from this module, you need to put a differential amplifier with bipolar power on the operating amplifier after the output from the module. On the module there are no outputs: left, right, Earth. There are two anti-phase signals in each channel. And when you think you 've connected one anti-phase (Inverter) signal of one of the channels, like the total minus for the headphones, you have a steropanoram narrowing to no (or when both inverter outputs you connected to the general on the headphones). Here are the measurements of this module (only one channel). In principle, yes, the characteristics are not bad (except for the head of the frequency response after 15 kHz, and this is without load).

It turns out you need to close for 5 seconds. Pin Power and Power EN (third contact from below). Dibils who ordered this module do not properly connect the output signal and also happy with what class transparent sound they have there. Are you even jerks? To get a good sound from this module, you need to put a differential amplifier with bipolar power on the operating amplifier after the output from the module. On the module there are no outputs: left, right, Earth. There are two anti-phase signals in each channel. And when you think you 've connected one anti-phase (Inverter) signal of one of the channels, like the total minus for the headphones, you have a steropanoram narrowing to no (or when both inverter outputs you connected to the general on the headphones). Here are the measurements of this module (only one channel). In principle, yes, the characteristics are not bad (except for the head of the frequency response after 15 kHz, and this is without load).
