## Ordering PCBs
You can find the latest Gerbers attached to the [latest Release](https://github.com/LIV2/RIPPLE-IDE/releases)

I recommend ordering from JLCPCB as this board was designed within their 2-layer specifications  

BOM and Placement files for JLCPCBs assembly service are provided and can be found inside the Gerbers folder and the Gerbers.zip file found under [Releases](https://github.com/LIV2/RIPPLE-IDE/releases)

Recommended options when ordering:
* Thickness: 1.6mm
* Surface Finish: ENIG-RoHS
* Gold Fingers: Yes
* 45°finger chamfered: Yes

## Programming
To program the Flash, simply boot the latest [lide-update.adf](https://github.com/LIV2/lide.device/releases/latest) boot disk

The CPLD can be programmed using a Raspberry Pi [as described by LinuxJedi](https://linuxjedi.co.uk/2020/12/01/programming-xilinx-jtag-from-a-raspberry-pi/)

## Revision history
* A5 - Fixup R10/R11 silkscreen - they had been swapped arouund on Rev A3 and A4
* A4 - Change flash footprint from TSOP to PLCC because the TSOP version is no longer manufactured.
* A3 - Add protection for reverse installation
* A2 - Add bank selection, support loading CDFS from flash
* A1 - Initial release

## Errata
Revisions A3 and A4 had a silkscreen issue with R10/R11 labels swapped around - R10 (150 Ohm) should be above R11 (10K)

## Special Thanks and Shoutouts
Thanks to:
* GadgetUK164, Screemo, Sparx, Mafitzee, Pillock for Beta testing the board
* Stefan Reinauer and Chris Hooper for creating the Open-Source A4091 driver which was the inspiration to create lide.device used by RIPPLE
