FAQs
Can this board be powered from a USB port?
No, the board requires a +4 to +9V external power source. It has onboard regulation for +3.3V.
Do I need a programmer to use the PIC32?
No programmer is required for most use cases, but a 5-pin header is available if you wish to reprogram the PIC32 firmware directly.
Can I use this board without the PIC32, using my own MCU or system?
Yes, the FPAA can be used independently. The board gives you access to all relevant pins, and you can bypass or isolate the PIC32 section.
Are the Rauch filters active or passive?
The Rauch input filters are passive and can provide single-ended to differential conversion in addition to low-pass filtering.
How does this board handle differential-to-single-ended conversion and filtering?
The optional output buffer stage converts the FPAA’s differential outputs to single-ended signals for easier interfacing with external measurement or processing circuitry. It can also include optional low-pass filtering to reduce noise and improve signal integrity.
How do I store and recall configurations?
The board allows FLASH-based configuration storage and can boot with a saved circuit automatically.
What’s the best clock speed to use for general applications?
Most users start with 16MHz. External clocks up to 40MHz can be used, but the system clock dividers must keep the on-chip system clock at 16MHz or below.
