PentiumPC 119 Posted October 19, 2011 Share Posted October 19, 2011 BluePack BoosterPack PCB Wiki Link 43oh Store Link SeeedStudio Store Link HI Guys,,I will be making a breakout board / Launch Pad booster pack for the Bluetooth module.This will be my first attempt in making a SMD Board.My idea is to make a Booster Pack that can be used as a breakout board as well.The Bluetooth module is mounted on the underside of the board to solve routing issues and save space, LEDs and most other passives on top.Board size is around 50mm x 35mm, well within the 50 x 50 cheap service from Seeed studio PCB service.(add proto area??)The board will also take HC05 or HC06 pin out, just solder the resistors and LEDs where you need it.I add in switch only for HC05 as you only need a switch if you have a HC06 Master module. (most sold on the Net are Slave module).All pin are broken out incase you want to hack / or reprogram the CSR chip.You can cut away the sides, if you only want it as a breakout board.SMD component size is 0805 (too small?).This is the first design.Comments welcomed.

gwdeveloper 275 Posted October 19, 2011 Share Posted October 19, 2011 Nice! With all the booster packs everyone is coming up with, I'm going to need more Launchpads. Quote Link to post Share on other sites
RobG 1,892 Posted October 19, 2011 Share Posted October 19, 2011 Nice! With all the booster packs everyone is coming up with, I'm going to need more Launchpads. Either that or use stackable headers... Quote Link to post Share on other sites

RobG 1,892 Posted October 20, 2011 Share Posted October 20, 2011 Just use this forum's search feature "stackable headers" Quote Link to post Share on other sites
PentiumPC 119 Posted October 20, 2011 Author Share Posted October 20, 2011 Cleanup the silkscreen, add in labels for all pin, rearrange stuff a bit. Still able to convert to breakout board. ( bit tight, need to cut properly.) Made provision for Hardware UART. (pin swap). Here is the the final look. (updated with new picture, fixing the mistake pointed out by RobG.) gssmahadevan 1 Quote Link to post Share on other sites
RobG 1,892 Posted October 20, 2011 Share Posted October 20, 2011 Check your switch and RESET pin connection. PentiumPC 1 Quote Link to post Share on other sites
PentiumPC 119 Posted October 20, 2011 Author Share Posted October 20, 2011 Check your switch and RESET pin connection. Thanks Rob, you saved me a few weeks of waiting time and fabrication cost. Pressing the switch will short 3v3 direct to ground. lol.. wonder what it will kill in the process. It is carelessness and I don't have any excuse for it.. (er.. actually I am sick..lol) I was about to send it out but something tell me not to.. lol... sending it out tomorrow.. Thanks once again. Terence Quote Link to post Share on other sites
RobG 1,892 Posted October 20, 2011 Share Posted October 20, 2011 Happens even to the best of us. I thought this was a reset switch but now I see this is a master switch, right? Very cool stuff, just ordered one of those. Quote Link to post Share on other sites

Switch to set the HC-05 to accept the AT command for master mode. you ordered a HC-05 or HC-06?? RobG 1 Quote Link to post Share on other sites
RobG 1,892 Posted October 20, 2011 Share Posted October 20, 2011 I got the same one you have, which is HC06 I believe. I could definitely use a breakout board Quote Link to post Share on other sites
Fred 453 Posted October 20, 2011 Share Posted October 20, 2011 That looks great. If it helps with fabrication costs then I'd definitely be happy to take one or two boards. I'm in the UK so no idea if that helps or not. Quote Link to post Share on other sites

kenemon 29 Posted October 20, 2011 Share Posted October 20, 2011 Are you sure it is OK to run underneath the module, I thought I read that this is to be avoided if possible, for interference reasons? Quote Link to post Share on other sites

Hmmm.. ok thanks, noted. I try to do some test on that. but these are so cheap, I don't think they have much range..to be affected.. Quote Link to post Share on other sites
