PanicWB is our new displayless standalone WBo2 module, it has RS232 and three different voltage outputs.
If someone want to have a readout directly, they can either: Hook up a DVM /analog voltmeter to an output or use the information avaible on RS232
Question: Can a generic "lambda meter" be used with this?
- A LED-bar or numerical display? I think both can be used with some firmware mods -Johan
- Something like http://store.summitracing.com/egnsearch.asp?N=4294925228+4294925227+4294822093+4294908391 (I think it will work, but I rather use a DVM or wait for Tiny ) -Johan
- Tiny is to be used as a generic lambda meter

Todo:
- Check for errors and general overlook of board
- Work on the ground planes (vias) Progress has been made....
- Find a comercial name for this product
Suggestions:
- add some kind of identifing name and version number -Good idea, we'll make this in the copper layer (when we know what to call it)
Done:
- Changed to polyswitch onboard. There is still need for an external fuse!
- Flood is gone= Isolation 10 on GND planes
- add VEMS logo to the board
- Change led ouput from PB4 to PD4
- MAX232 area. We agreed earlier to drop max232 (there is FBUS cable for both RS232 and USB), but it fitted so well that is was left on. OK.
- Mega88 area
- PSU area
- ISP connector will fit in case
- Changed:
- Aut to pin 1
- Etas to pin 9
- 0-5v to pin 10
Name suggestions:
Wideboard fits with Genboard, but VEMS Wideband will mean less confusion by the punters. Wideband, WBO2, UEGO are commonly understood.
- VEMS WideBand
- Keeps it simple...
- How about just "Wideband" - most folks don't "get" the joined capitals thing.
- I belive that "VEMS Wideband" and a "lambda" logo would make a great sticker for the case -Johan
-
VEMS WideBoard- Sounds big
- Has board in the name
-
GenOxy- Sounds backwards - many folks won't connect GenOxy with Genboard
-
OxyGenboard(OxygenBoard?)- Many folks won't connect OxyGenboard with Genboard
- Has board in the name
-
LambdaBoard- Has board in the name
-
Greek Lambda symbol, either uppercase or lower. Uppercase is less common- Relying on scientify/linguistic knowledge is probably not ideal
- The symbol is more a logo than a name, just for visual effects ;)
(2nded) -Rich
Dropped:
- Board layout for 82mm profile:
- Board width: 76mm
- Width free for routing: 70mm
- Width free for full height components: 67mm.
- Board length: 48mm.
- Connectors must sit side by side and must sit as far apart at possible.
- SMD LEDs. Though the endplate quality can be assured, SMD means less manual work.. 3mm ordinary thruhole LED's with lenses in the endplate would make it look professional enough. How about lenses in the plexi endplate and SMD LEDs ?
