Product Description

 

STEMlab 125-14 External clock Starter kit

 

CAUTION: This board needs an external clock signal 125MHz in order to function!

STEMlab 125-14 External clock is based on the STEMlab 125-14 model that is modified to be used with an external clock oscillator, which is important especially for RF applications that operate at other frequencies, require better quality clock or clock synchronization.

With this modification, users can provide their own clock for the Red Pitaya device through the E2 extension connector.

What is in the box

- Red Pitaya STEMlab 125-14-Low Noise board
- SD card (16GB, class 10)
- Ethernet cable (1m)
- Power supply (5V, 2A)
