Debug Capacitive Touch PCB
Budget: $10 – $100 AUD
I need help diagnosing a malfunction in a capacitive touch PCB with fewer than 10 components. The board exhibits unexpected behaviour when powered on.
Key details:
- The PCB is intended to emulate a touch interaction when placed next to a touch screen
- It fails to operate as expected upon power-up.
- When signal is HIGH, it is low-impedance to ground instead of high-impedance.
Ideal skills and experience:
- Proficiency in PCB design and troubleshooting
- Experience with capacitive touch technology
- Ability to diagnose and fix electronic circuit issues
Please do not send me your previous experience, work or past reviews.
YOU MUST respond with at least one technical question related to my task. I do this for filtering unwanted automated responses. To those who know: I am using esp64-c3 microcontroller.
