DIG Card
About the DIG Card PCB
DIG Card is an open source NXP PCB design by scular-HCC, published on GitHub under the Custom license license. It is a 6-layer board measuring 160 × 100 mm, with 187 components from 101 distinct parts.
Its main chip is the TEENSY_4.1, from the NXP family. Other key parts include the AD9833BRMZ, LMV7219M5/NOPB, SN74LVC1G3157DBVR, CDCE913PWR and 1568-COM-28379. By type, the board carries 36 capacitors, 26 resistors, 12 diodes, 11 ICs, 9 LEDs and 4 connectors.
It belongs with the test & measurement designs in this gallery.
From the project
Dual laster Pound-Dreaver-Hall driver setup. 1550 nm DFBs. Q=10^-5. Less than 20 GHz difference
A precision two-channel controller for 1550 nm DFB butterfly lasers — a differential optical thermometer built as a 3U Eurocard instrument.
Each channel provides low-noise constant-current laser drive, a bipolar linear TEC temperature controller, RF frequency modulation, and a synchronous-demodulation Pound–Drever–Hall lock that holds the laser to the side of an optical resonance. Lasers A and B lock to their own fringe of a shared reference cavity; the beat frequency between them, Δν = S·(TB − TA) with S ≈ 2 GHz/K, is a ratiometric measurement in which slow common-mode drift cancels.

DIG Card: common questions
What microcontroller does the DIG Card use?
The DIG Card is built around the TEENSY_4.1, from the NXP family.
How big is the DIG Card PCB?
The DIG Card measures 160 × 100 mm, has 6 copper layers and is 1.5584 mm thick.
How many components are on the DIG Card?
187 components, from 101 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 DIG Card design files?
From the scular-HCC/DualLaserPDHDriver 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 DIG Card design in my own project?
It is published under Custom license, which limits how it may be reused; read the license before building on it.
Can I test firmware for the DIG Card without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
