During the past few years it has been difficult to source the USB interface used on the KIM Clone and SS-30 USB serial board. I had to resort to black market parts while waiting for orders from large distributors to slowly arrive. Well, that chip has been discontinued and replaced with a new chip.
The fastest way to test a new design with the new chip was to update the SS-30 USB board… a re-spin of the KIM Clone is coming, but not soon. So, here is the new board:
The new chip is at the far right, underneath the USB connector. Fewer pins so a bit easier to solder! The labels on the TX/RC LEDs have been fixed to show the right direction. The baud rate oscillator socket can take either 8 or 14 pin devices. There are no other changes from the previous version of the board.
