Is there any possibility to use sequential injection with the module?
Maybe with a hardware hack, like the one for the MSII daughter card?

Re: Microsquirt Module General Information
What are the additional 4 and 6 pin headers for, and what are their coordinates?
Also, in the schematic I see a V12U that doesn't appear to be brought out anywhere. Is that on one of the undocumented headers?
Thanks!

Re: Microsquirt Module General Information
These headers are what I use to program and check the board - they are BDM header and serial lines. You do not need to use these, everything needed is on the two main headers.JustinHoMi wrote:What are the additional 4 and 6 pin headers for, and what are their coordinates?
This is just another take-off from the +12V supply, it was used on an earlier uS version. Just ignore for your use.JustinHoMi wrote: Also, in the schematic I see a V12U that doesn't appear to be brought out anywhere. Is that on one of the undocumented headers?

Re: Microsquirt Module General Information
Are those serial lines logic-level, perchance?

Re: Microsquirt Module General Information
No, these are the same RS-232 level signals that are on the header. If you need logic level serial then you need to run a level translator chip (like MAX232). I personally like the new ADI isolated serial transceiver, it will yield logic-level serial that's isolated....JustinHoMi wrote:Are those serial lines logic-level, perchance?
