Digitizer
About the Digitizer PCB
Digitizer is an open source PCB design by AntonSievering, published on GitHub. It is a 2-layer board measuring 36 × 37.3 mm, with 44 components from 18 distinct parts.
Other key parts include the 595-TPS7A4700RGWR, 926-ADC08060CIMTXNPB and 584-AD8051ARZ-R7. By type, the board carries 17 capacitors, 17 resistors, 3 ICs, 2 connectors, 2 test points and 2 diodes.
From the project
Sounding Rocket Tracking and Positioning Project
The rocket carries a transmitter that continuously downlinks telemetry along with timing signals. Multiple ground receivers (3–4 planned) receive the signal and extract the timing information. With the timing data, the system computes the rocket’s position in real time.
This repository contains the PCB projects for TRACKER - GPSDO-V2: 10 MHz oscillator tuned by the GPS timing signals - basestation-rx: S-band timing signal receiver - tracker-tx-fpga: FPGA baseboard with three subcarrier slots - tracker-subcarrier-adc: ADC subcarrier for FPGA baseboard - tracker-subcarrier-dac: DAC subcarrier…

Digitizer: common questions
How big is the Digitizer PCB?
The Digitizer measures 36 × 37.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Digitizer?
44 components, from 18 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Digitizer design files?
From the AntonSievering/TRACKER repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Digitizer design in my own project?
The repository has no license, so all rights stay with AntonSievering. Use it as a reference, and ask the author before reusing the design.
