PCB Design Bluetooth ADC
Budget: $10 – $30 USD
I need a PCB design and parts suggestions for my project, with the following requirements:
- Reliable measurement of Velostat resistance, without significant noise.
- Bluetooth communication capability.
- Powered by a USB cable.
- Smaller size compared to the prototype.
I currently have a working prototype (ESP32 + external ADC because there is too much noise on the ESP32 ADCs), but I need a smaller solution with a custom PCB.
