FAQs

Is this board compatible with all Raspberry Pi models?

The OTC2310K04-PIKA board is designed to work with Raspberry Pi models featuring the standard 2x20 GPIO header. Compatibility may vary with newer Pi models that change this interface, so please check the specific model before use.

Can I use this board with Arduino or other microcontrollers?

Yes, the OTC2310K04-PIKA board can work with Arduino and other microcontrollers, but it only supports 3.3V I/O. Since many Arduino boards use 5V I/O, you’ll need external level shifting.

What’s the benefit of having four FPAAs on one board?

Four FPAAs allow for parallel processing of multiple analog signal channels, enabling complex multi-channel analog designs and more flexible system architectures.

How is power managed on this board?

The board supports dual power options and can be powered either through the Raspberry Pi’s GPIO header or an external supply. It includes automatic selection and onboard regulation to provide stable +3.3V rails.

Is stacking multiple PIKA boards supported?

Yes, the board supports daisy-chaining and vertical stacking to expand the number of FPAAs and increase system complexity.

Does the board include a clock or rely on the host?

The board includes a 16 MHz onboard analog master clock and also supports using an external clock source from a Raspberry Pi.
