uTracer 3 /3+ upgrade processor

Replacement upgrade processor for the uTracer 3 and 3+. 40 pin progammed DIP

Drop in chip that provides improved accuracy and speed over the original. Complete redesign from the ground up 

• 12 bit grid voltage (up from standard 10 bit). Requires the free uTmax GUI V2.20 or higher.
• 2KHz heater frequency greatly improves accuracy at high heater currents.
• Dynamic pulse with modulation of boost coverter for increased speed and accuracy.
• 4x oversampling of curent and voltage for lower noise and improved accuracy.
• Better handling of communications to reduce frustrating comms losses
• Switchable low / high current ranges for better accuracy
