3.1.1.2.1. Technical specifications¶
3.1.1.2.2. Schematics¶
Note
FULL HW schematics for the Red Pitaya board are not available. Red Pitaya has open source code but not open hardware schematics. Nonetheless, DEVELOPMENT schematics are available. This schematic will give you information about HW configuration, FPGA pin connections, and similar.

3.1.1.2.5. Extension¶
3.1.1.2.6. External ADC clock¶
The ADC clock can be provided by:
On board 125MHz XO (default)
From an external source/through extension connector E2 (R25, R26 should be moved to location R23, R24)
Directly from the FPGA (R25, R26 should be relocated to R27, R28)

3.1.1.2.7. Certificates¶
Besides the functional testing, Red Pitaya passed the safety and electromagnetic compatibility (EMC) tests at an external testing and certification institute.
3.1.1.2.8. Cooling options¶
For additional cooling, we recommend a 30 mm or 25 mm fan. You can utilise the power connector on the board to power the fan, but please note that it supplies only 5 V. The power connector is located between the micro-SD socket and the host USB connector.
Note
The power connector is a standard 2-pin 0.1” connector. Supplies only 5 V.
