Revision of the EzSBC1

Revision of the EzSBC1

Postby Daniel » Thu May 14, 2020 2:25 pm

The EzSBC1 is an old product and I revised the board recently to be easier to manufacture given my current part usage. Here are the changes:

Mini USB removed and replaced with a Micro USB connector.
FTDI USB to Serial converter replaced by a SiLabs CP2104 converter.
32.768 crystal changed to a small form factor crystal.

The board is functionally identical and the pinout is unchanged. The reasons for the changes are varied and a short explanation follows. The Mini USB connectors are becoming expensive or poor quality. The FTDI USB to serial converter has become really expensive and it is large. I don't use it on any other product anymore. The 32.768 kHz crystal is now the same part as used on may other boards that I manufacture.

I have used the revised boards, and they are just as good as the old ones - and a little smaller, to boot. Well done!

Note, however, that on a Mac, the terminal login to the board is now different:
screen /dev/cu.SLAB_USBtoUART 57600 cs8, ixon, ixoff
No serial number is needed, anymore.

(See the previous topic re. some difficulties using the Mac Terminal app with the EzSBC1 - I'm still investigating, hoping to find a solution for fast loading.)
