About the Alex-Harris-Capstone PCB

Alex-Harris-Capstone is an open source PCB design by achihuahua22, published on GitHub under the MIT license. It is a 2-layer board measuring 65.5 × 56.4 mm, with 49 components from 18 distinct parts.

Other key parts include the MAX3232CDR, 568-4016-5, SN75161BDW and SC16IS752IBS. By type, the board carries 19 resistors, 12 capacitors, 9 diodes, 5 connectors and 4 ICs.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

This project builds on an-ven’s graspib project by adding more RS232 support and a UART breakout pin.

This project builds on an-ven’s graspib project by adding more RS232 support and a UART breakout pin.

Currently, this device supports UART, RS232, and GPIB.

If you want to make one yourself, the files are here

1. RS232 2. CAN (CAN-FD, etc.) 3. GPIB 4. USB 5. UART 6. HPIB 7. Ethernet

Obviously, it is not possible to develop a device to encompass every existing communication protocol, so I chose three that were most necessary to our SDL and were most feasible with the constraint of a Raspberry Pi powered device. The three protocols I chose were RS232, UART, and GPIB. I chose each of these…
