Debug Capacitive Touch PCB

Job ID: 39733413

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.
