An issue with stringing multiple PPS MUXes together led to this updated design.
An Arduino Nano controlled board for a user supplied 5 or 10 MHz signal for comparison against a reference PPS.
New version of MUX controller with +5 and -5 V supplies
Interface board for GPSDO with serial port comms.
A board to test a linear regulator (low dropout) powering the Pi 5 through the GPIO connector.
The quality is very good, as always! Descript_ion: This breakout board has two PPS inputs with signal conditioning followed by amplifiers providing two outputs for each input. The PPS signals are a...
Testing part of the functionality of a power control board for a battery operated instrument.
Using an Arduino this creates two pulse-per-second signals that is fed to a TAPR TICC time interval counter. It expects a 10 MHz reference oscillator and a 5 or 10 MHz unit under test oscillator.
A manual controller for the +5V / -5V version of the PPS MUX. Used to test various amplifier designs.
Redesign of output amplifier requires testing of different circuits. This board provides that functionality. PCB quality is excellent, as always.
Pi5 GPIO power and breaking out some ports
Swapped the switch mode supply for a linear supply. This board is to test the linear supply (based on the LTI1592)
Good quality as always! Thanks.
A new revision of the PPS divider. Now with a better input stage.
