Two days ago I tagged as Version 1.0 on the GitHub everything that was in the Master branch. That is design with separate pre- and post-regulator boards and Arduino shield with TFT touch-screen with portrait/vertical orientation. We'll continue to support that design together with the new where power board with SMPS pre-regulator is introduced and Arduino shield comes with TFT oriented horizontally.

An updated Arduino shield board r3B3 can be found here. The main difference from preliminary version (r2B6b) is TFT that is rotated 180 degrees, channel's connectors are moved on the right side and sync master signal that comes from AUX PS is now also incorporated on the board to reduce required number of connected cables. And yes, optional connectors are also added for the following:

• W5500 Ethernet module (if you found that cheaper/simpler then adding W5500 on the shield)
• WiFi NRF24L01
• Rotary encoder

AUX PS board r5B8 can be found here. Only two changes are added: Sync out and power connector are merged into one, and optional USB isolator (ADuM3160) is added if someone wants to isolate the PSU from PC.
Finally, the Power board r5B8 can be found here. Things are moved around a little bit, it's now possible to power it from AC or DC input and remote sense polarity reverse protection circuit is also added.

Anyway we're approaching the final phase of the hardware part for what is also planned a group buy.
