Plimsoll
About the Plimsoll PCB
Plimsoll is an open source PCB design by mulcmu, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 15.1 × 29.2 mm, with 11 components from 6 distinct parts.
Other key parts include the ADS1220XPW and RS3236-3.3. By type, the board carries 7 capacitors, 2 ICs and 2 resistors.
From the project
Kicad PCB design with XH717 ADC to support Klipper load cell
Prototype designs for klipper load cell ADC implementations.
STM32F072 and HX717 based strain gauge for use as a Klipper load cell.
Initial batch ordered for testing with JLCPCB. About 5.5 USD cost per board.
Firmware and configuration tested with current community test branch.
Smallish size, 20x50 mm footprint. M2.5 mounting holes. Fab house added the smaller tooling holes...
