From the project
tubes
td-deflect is the primary PCB of td-crt, containing most of the pieces of a complete chassis.
The chassis is a multisync design with separate HV and deflection, allowing arbitrary scan rates, within the voltage and current limits of the ciruit.
There is a completely analog RGB path, based on a M51387P RGB amplifier IC. While effective, the chip has been out of production for a long time and therefore the td-rgbinput board exists as a future design that eliminates the IC.

Td deflect: common questions
What microcontroller does the Td deflect use?
The Td deflect is built around the STM32G474VETx, from the STM32 family.
How big is the Td deflect PCB?
The Td deflect measures 174 × 104 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Td deflect?
165 components, from 76 distinct parts. The full bill of materials is listed on this page.
Where can I download the Td deflect design files?
From the tdaede/td-crt repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Td deflect design in my own project?
The repository has no license, so all rights stay with tdaede. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Td deflect without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
