@copilot can I tell you an idea and you build schematics for it and pcb for it
11mo
Absolutely, I'd be happy to help you with that! Please go ahead and share your idea, as well as any specific requirements or components you have in mind. The more details you provide, the better I can assist you in creating the schematic and PCB design.
11mo
OK I want to design two operate circuit one for transmitter that has aux to microphone and other as receiver that has auz f
11mo
Great! It seems like you're looking to create a wireless audio transmission system. Let's break down the requirements for each part of your system:
Transmitter Circuit
- Input: AUX input from an audio source (like a phone or MP3 player).
- Output: Wireless transmission of the audio signal.
- Components:
- Audio pre-amplifier (if needed).
- Wireless transmitter module (e.g., Bluetooth or RF module).
- Power supply (battery or another source).
- Input: Wireless audio signal.
- Output: Audio output through an AUX connection.
- Components:
- Wireless receiver module (complementary to transmitter module).
- Audio amplifier (for driving output speakers or headphones).
- Power supply (battery or another source).
Here are a few questions so I can better assist you:
- What range are you aiming for between the transmitter and receiver?
- Do you prefer a particular type of wireless communication (e.g., Bluetooth, RF)?
- What power source are you considering for both the transmitter and receiver?
- Are there any specific size or form factor constraints for the PCBs?
Feel free to answer these questions, and we can start working on the schematic and PCB design.

- I want to send normal clear voice
11mo
Got it! For transmitting clear voice wirelessly over a moderate range, Bluetooth is a popular choice due to its ease of implementation and good audio quality.
Let's refine the project details:
Transmitter Circuit
- Input: AUX from an audio source.
- Output: Bluetooth transmission.
- Components:
- Bluetooth audio transmitter module (e.g., BC05-B, CSR8635).
- Optional audio pre-amplifier if needed.
- Power supply (battery, perhaps a 3.7V LiPo).
- Input: Bluetooth audio signal.
- Output: AUX to speaker or headphones.
- Components:
If that plan sounds good, we can start building the schematic. Let me know if you have any more specific requirements or if you'd like any modifications to this plan!

@copilot the size should be easy to manufacture and easier for hand soldering still compact I am going for 2 layer pcb also type of communication rf sound good power source can be with lithium battery
11mo
Great! Using RF communication for audio transmission can work well, and designing the circuits to be compact yet hand-soldering-friendly on a 2-layer PCB is a reasonable approach.
Updated Plan:
Transmitter Circuit:
- Input: AUX from an audio source.
- Output: RF transmission.
- Components:
- Input: RF audio signal.
- Output: AUX to speakers or headphones.
- Components:
- Select specific RF modules that match your range and frequency requirements.
- Create a general block diagram to visualize your circuit architecture.
- Begin drafting the schematic in Flux.
Before going ahead with the schematic, do you have preferences for:
- A specific RF frequency (e.g., 433 MHz, 2.4 GHz)?
- Any additional features (battery level indicator, power switch, etc.)?
Let me know your thoughts, and we can proceed accordingly!
11mo
OK go
11mo
Let's start with a block diagram to layout the structure of your transmitter and receiver circuits. Here's a basic representation using a block diagram:
Image
- RF Frequency Range: Common frequencies for RF communication include 433 MHz or 2.4 GHz.
- Battery Management: You might want to include a module for charging and protecting the Li-ion battery.
- Audio Quality: Ensure that the selected RF module can handle the bandwidth for clear audio transmission.
You'll want to integrate the specific components related to each block in the diagram:
- RF Modules: Include connections for power, data, and an antenna.
- Audio Amplifier: Ensure it can drive your desired output load.
- Battery System: Include charging IC and voltage regulators for consistent power delivery.
- Optional Features: Consider adding any additional LED indicators or switches, as needed.
Do you have specific RF modules or audio amplifiers in mind for your design, or would you like suggestions? Let me know, and we can move on to the schematic design in Flux!
11mo
I want you to start building circuit from information you have so far you can add details that you think is suitable to add to make cool circuit
11mo
Let's dive into creating the schematics for both the transmitter and receiver circuits using the details we've outlined. Below are the assumptions and decisions we'll make to proceed:
Transmitter Circuit
- RF Transmitter Module: We'll use the RFM12B for RF transmission, operating at 433 MHz.
- Audio Pre-Amplifier: Use an LM358 op-amp to ensure that the audio signal is at an adequate level for the RF module.
- Power Supply:
- A 3.7V LiPo battery.
- MCP73831 for battery charging.
- AMS1117-3.3 for voltage regulation.
- RF Receiver Module: Complementary RFM12B for receiving the signal.
- Audio Amplifier: Use the TPA3118D2 to drive audio output.
- Power Supply:
- A similar power setup using a 3.7V LiPo battery.
- Battery level indicator using a simple LED circuit.
- SPST switch for power control.
Now, I'll start building the schematic for both circuits. This will take a little time. Let me know if you have any specific preferences or changes while I work on it!
I'll outline the schematic connections for the transmitter and receiver circuits:
Transmitter Schematic
-
Audio Input and Pre-Amplifier Circuit:
- Connect AUX input to LM358 op-amp input.
- Output of the op-amp connects to the RF module's data input.
-
RF Transmitter Module (RFM12B):
-
Power Supply Circuit:
-
RF Receiver Module (RFM12B):
-
Audio Amplifier:
-
Power Supply Circuit:
- Battery level indicators can be added using a Zener diode and LED, showing status through color coding.
Creating this system as compact and hand-solderable requires arranging these components effectively on a 2-layer PCB. Are there any additional features or specific customizations you'd like, or shall we proceed to the PCB layout design in this format?
