BlueSaab v5.0!

Sorry for not posting here lately; I've been busy on the forum and the FaceBook pages.

Here's v5.0!

This version changes all resistors and caps to 0805 to save space and make room for other things.

Got rid of DFU switch because using signal diodes removes the need for it.

Vertical USB connector for uploading code without the need for an external FTDI cable/adapter.

FTDI cable/adapter is still an option.

Changed to a high temp CAN transceiver, with the future ability for sleep (power savings).

Added 10-pin connector for "future use" ;)

Version 4.1 is here!

This is a large change from v3.x.

- Switched from through hole atmega328 to surface mount atmega328.
- Added ISP header for programming new SMD 328 bootloader.
- Added on-board FTDI adapter so uploading code is as easy as plugging in a mini USB cable.
-- Still has 6 pin FTDI header so you can still use external FTDI adapter to program.
-- Added status LEDs for on-board FTDI uploading (rx/tx).
- Switched to a new voltage regulator that MUCH more common/easy to find.
-- Added heatsink area for vreg.
- Changed the way the board is powered; now all power inputs go through their own diode, and THEN to the vreg, so they're all isolated, and now the vreg output is a clean 3.3v.

FaceBook

Wanted to share the FaceBook page for BlueSaab, here.

Here's what v3.2 pcb looks like bare, and when finished :)

These pcbs were ordered from DFRobot, specifically asking for blue pcb color; OSHPark only makes pcbs in purple.

PCB v3.2 (BOM unchanged)

I've posted the latest PCB revision in the forum.

Mainly cosmetic changes and improved the layout.

BlueSaab v3.1 BOM & PCB

I'm getting a lot of requests for the BOM & PCB, so here they are. I'm also posting this in the forum.

BlueSaab Forum

At Karlis' suggestion, I've added a forum to the blog so people can ask questions and add comments easier (I hope) so that it will be more of an interactive discussion regarding the development of the module.

Feel free to start using it :)

The link should be on the right side, under "About Me".
