dac-brd: Raspberry Pi Pico 2 based board with 2x 8 channel DACs supplied by a 2.048V precision reference voltage.amp-mezzanine-v2: A mezzanine board that supports stacking 4x AMP boards. The mezzanine takes power and control signals and pass them to the AMP boards.amp-brd-v3: A DC-DC converter board with controllable reference voltage that allows adjusting its output voltage between 0V (1V control) and 25.7V (0V control, Vin > 25.7V). An on-board INA233 monitors the output voltage and current, and a DS28EA00 1-Wire temperature sensor reports board temperature.amp-brd-v4: A future, in-development version that integrates monitoring and control features using a USB-PD chip. It would allow all 16 boards on one stack.

Questions
How big is the Amplifier brd PCB?
It measures 32.5 × 30 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Amplifier brd use?
34 parts, built around the DS28EA00U+, LMR36510ADDA and BSS84. 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 Amplifier brd KiCad files?
From the sunipkm/piccheater-pcbs repository on GitHub, at the commit this page was made from: the board is amp-brd-v3/amplifier-brd.kicad_pcb and its schematic amp-brd-v3/amplifier-brd.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Amplifier brd design in my own project?
Its repository states no licence, so its author keeps all rights: ask sunipkm before reusing the design.
