ThunderScope Update: PCB Design Challenges and Shipping Delays

2025-05-04

Aleksa from the ThunderScope project shared a project update. He spent six weeks on the PCB layout for Revision 5, boasting about integrating the ADC, clock generator, and FPGA. He also made subtle adjustments to the attenuator circuit and wrote a script to improve KiCad's length matching accuracy. Due to the new interposer design, the switch to KiCad, and some personal issues, the project is delayed. Dev edition units are expected to ship in July, with the rest shipping in September. Aleksa will be using GitHub Issues to track progress and will provide another update after testing Rev. 5.
