HSMC-GPIO
About the HSMC-GPIO PCB
HSMC-GPIO is an open source PCB design by calebreister, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 63.5 × 78.1 mm, with 113 components from 14 distinct parts.
Other key parts include the MC78M05_TO252 and PCA9507. By type, the board carries 44 resistors, 42 diodes, 20 capacitors, 4 connectors, 2 ICs and 1 jumper.
From the project
This is a project created to test my new HSMC Card KiCad footprints. It is based loosely on the Terasis HSTC-GPIO Card. In small quantities, the cost is comparable to the HSTC-GPIO Card.
