Here is the latest revision (r2B6) of the Arduino shield (digital control) board. It includes the following modifications:

  1. Existing ENC28J60 Ethernet controller is replaced with W5500
  2. One instead of two LED indicators is using for indicating power output status
  3. Existing TLC5925 LED driver is now using for driving CC and CV LED indicators on both channels

New schematic and PCB are shown below (only Sheet 1 and 3 were changed). With this modification this revision is completed.

I’m going to order a new PCB panel in coming days and also started let’s call it “experimental group buy” for all people who wants to follow me in this stage and somehow assist me to decease cost of PCB manufacturing. If anyone is interesting feel free to contact me.
