Revision B - 7/24/2024
Added
- Board characteristics to assembly drawing.
- Board dimensioning to assembly drawing.
- Test points at different stages of amplification.
- Layer indicator to top left of assembly drawing.
- L7912C Negative LDO (Will require additional power supply).
- Summing amplifier stage which will subtract a voltage from the output of the ADL5902-EVALZ in attempt to bring the noise floor closer to 0VDC
Changed
- Stackup changed from 2-layer, 30 mil RO4350b to 2-layer OSHPark specifications.
- Removed SMA connectors that allowed the stages of the PCB to be used independently as that functionality was not significant.
- Removed ADL5902 Power Detector IC and replaced with a footprint to mount the ADL5902-EVALZ directly on top. Oscillations were detected and further testing is not possible within the current time frame.
- L78XX TO-220 replaced with D2PAK.
Fixed
- Removed front and back mask from linear regulator pads to improve thermal conductance.
- 15V silkscreen text now correctly reads 12V
- Board dimensions and mounting hole patterns are rounded to clean values (5.05" x 1.8").
Revision A - 6/29/2023
First revision 🎉🎉🎉
- This directory contains KiCad files for the PCB. The PCB contains a 15V/5V 1A power supply, an ADL5902 power detector, and a dual LM358 non-inverting amplifier. It was designed to allow users to utilize the individual stages on projects outside of this application.

Questions
How big is the 002.35.25.05.20-001-PCB SolarTele PCB?
It measures 128.3 × 45.7 mm and has 2 copper layers, 1.63 mm thick.
What parts does the 002.35.25.05.20-001-PCB SolarTele use?
31 parts, built around the LM358, L7805, L7812 and L7912. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the 002.35.25.05.20-001-PCB SolarTele KiCad files?
From the RomiFC/Solar-Telescope-Redesign repository on GitHub, at the commit this page was made from: the board is PCB Design/002.35.25.05.20-001-PCB-SolarTele.kicad_pcb and its schematic PCB Design/002.35.25.05.20-001-PCB-SolarTele.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 002.35.25.05.20-001-PCB SolarTele design in my own project?
Its repository states no licence, so its author keeps all rights: ask RomiFC before reusing the design.
